What is the Municipal integrated Waste Water Filtration System: Sewage Water Purifier + RO Technology + Activated Carbon Adsorption Tower Solution?

With the acceleration of urbanization, municipal sewage has increased dramatically, posing a serious threat to the environment. Traditional wastewater treatment facilities use physical, chemical and biological processes, but they are inefficient, occupy a large area, are costly, and ignore waste gas treatment. 

To this end, XJY has launched an integrated treatment solution, dedicated to achieving the coordinated treatment of sewage, clean water and waste gas, and overcoming the difficulties in municipal wastewater management.

1. What is municipal sewage?

Municipal wastewater contains a large proportion of water, but contains dissolved and suspended pollutants, including organic matter, nutrients, pathogens, debris, gravel, etc.

Urban sewage pollutants come from a wide range of sources, including excrement and detergents in residential areas, chemical pollutants such as heavy metals from industrial and commercial activities, and pesticides from rainwater runoff.

Clarifying the sources will help develop multiple treatment plans for different pollutants to protect public health and environmental safety.

2. Design goals of waste water treatment solutions

Sewage discharge up to standard: ensure that the treated sewage meets the national or local emission standards and reduce the pollution of pollutants to water bodies.

Water resource reuse: through advanced water purification technology, realize the resource reuse of part of the treated water and improve the utilization rate of water resources.

Exhaust gas clean emission: effectively collect and treat the waste gas generated during sewage treatment to meet the emission standards required by environmental protection and reduce air pollution.

System efficiency and stability: build an integrated treatment system to improve treatment efficiency, reduce energy consumption, ensure long-term stable operation of the system, and reduce maintenance costs.

3. What are the processing techniques of waste water solutions systems?

Municipal wastewater management involves the collection, treatment, disposal and reuse of discharged water. Next, these links will be introduced in detail.

3.1 Sewage water filter system Collection

Sewage collection is the key link at the beginning of the entire treatment process, and XJY has taken a series of powerful measures for this purpose.

Pipeline network inspection and transformation: Conduct a comprehensive inspection of the municipal sewage pipeline network, repair damaged pipelines, implement rainwater and sewage diversion transformation, and ensure effective sewage collection.

Intelligent monitoring system: Establish a geographic information system (GIS) to realize the informatization and account book management of the sewage pipeline network and improve the efficiency of sewage collection.

3.2 Sewage water purifier process

XJY's sewage treatment process can not only remove pollutants, prevent water pollution, and protect the ecological environment, but also realize the recycling of water resources.

Integrated sewage treatment equipment: Integrated sewage treatment equipment is adopted, including pretreatment unit (grid, grit chamber), biological treatment unit MBR process, deep treatment unit (flocculation sedimentation, filtration) and disinfection unit (ultraviolet or ozone sterilization).

Modular design: The equipment adopts modular design, which is convenient for rapid deployment and expansion to meet the needs of sewage treatment of different scales.

High-efficiency nitrogen removal and phosphorus removal technology: Anaerobic ammonia oxidation (ANAMMOX) technology is applied to improve nitrogen removal rate and reduce agent consumption.

3.2.1 What is XJY's MBR process?

MBR is the abbreviation of Membrane Bio-Reactor, which is a sewage treatment process that combines membrane separation technology with biological treatment technology.

Principle:

The MBR process uses the efficient separation effect of the membrane component to retain the activated sludge and macromolecular organic matter in the bioreactor in the reactor, making the effluent water clear and the suspended matter and turbidity almost zero. At the same time, microorganisms are enriched in large quantities in the reactor, which can efficiently degrade organic matter and remove pollutants such as ammonia nitrogen.

Features:

●Good water quality: Efficiently remove suspended matter, organic matter, bacteria and viruses, and the effluent can be directly reused for irrigation, landscape water replenishment, industrial cooling and other scenarios.

●Small footprint: With the high efficiency of membrane separation, large secondary sedimentation tanks and complex sludge treatment facilities are eliminated, greatly reducing the land occupation.

●Low sludge: Under high sludge concentration and long sludge age conditions, microorganisms are fully metabolized, and the sludge output is significantly lower than that of traditional processes, reducing treatment costs and difficulties.

●Easy operation and maintenance: high degree of automation, easy cleaning and maintenance of membrane components, stable system operation, strong resistance to water quality and water volume fluctuations.

Application areas:

Urban sewage treatment and reuse, industrial wastewater treatment, building water reuse, rural sewage treatment, etc.

3.3 What is water purification like?

Water purification aims to remove all kinds of impurities and harmful substances in water, meet the standards for drinking water and industrial production water, and realize the recycling of water resources.

Pre-filtration:

Set up a pre-filter before tap water enters the house to remove large particles of impurities such as mud, rust, etc. in the water.

Central water purification system: Configure a central water purification system, including ultrafiltration, activated carbon filtration and other steps to ensure water quality safety.

Direct drinking water system: For places that require direct drinking water, XJY's RO reverse osmosis machine can be added to provide high-quality drinking water.

3.3.1 What is the RO reverse osmosis technology provided by XJY?

RO reverse osmosis technology is a technology that uses the principle of semipermeable membrane to achieve water purification.

Principle:

The semipermeable membrane has the characteristic of only allowing small molecules such as water to pass through, while preventing other solutes from passing through. Under normal circumstances, water will penetrate from the low-concentration solution side through the semipermeable membrane to the high-concentration solution side. This process is called osmosis. However, if a pressure greater than the osmotic pressure is applied to the high-concentration solution side, the water will flow in the opposite direction, from the high-concentration solution side through the semipermeable membrane to the low-concentration solution side, thereby achieving water purification and separation of solutes.

Features:

●High efficiency desalination: high removal rate of salts and heavy metal ions in water, can significantly reduce water hardness and conductivity, and produce high-purity water.

●Stable water quality: When the system is operating normally, the effluent water quality is not affected by the fluctuation of raw water and always meets high quality standards.

●Water-saving and efficient: only a small amount of concentrated water is discharged during operation, and compared with other technologies, the utilization rate of water resources is high.

●Easy to operate: high degree of automation, simple daily operation and maintenance, reducing manual workload and complexity.

Application:

Seawater desalination, brackish water desalination, drinking water production, industrial pure water preparation, purified water production in the pharmaceutical industry, ultrapure water preparation in the electronics industry, etc.

3.4 What is the process of exhaust gas treatment?

This process can remove harmful pollutants in waste gas and reduce its negative impact on air quality, ecological environment and human health.

Waste gas collection: According to the characteristics of production process and waste gas emission source, design a reasonable waste gas collection plan to ensure comprehensive collection of waste gas.

Pretreatment: Pre-treat the collected waste gas to remove impurities such as particulate matter and moisture.

Purification treatment: According to the composition and concentration of waste gas, select appropriate purification technology, such as adsorption method, catalytic combustion method, etc.

Emission monitoring: Install online monitoring equipment at the inlet and outlet of the waste gas treatment system to monitor waste gas emission parameters in real time to ensure that the emission meets the standard.

3.4.1 What is the activated carbon adsorption tower used by XJY?

The activated carbon adsorption tower is a device that uses the adsorption properties of activated carbon to purify air or treat wastewater.

Principle:

When waste gas or wastewater passes through the activated carbon adsorption tower, the pollutant molecules are adsorbed by the micropores on the surface of the activated carbon. The adsorption is based on physical and chemical adsorption. Physical adsorption is caused by the van der Waals force between the activated carbon and the pollutants, and chemical adsorption is achieved by the chemical reaction between the functional groups on the surface of the activated carbon and the pollutants. Large or polar molecules are more easily adsorbed. As the adsorption proceeds, the adsorption capacity of the activated carbon decreases. When it is saturated, it needs to be regenerated or replaced to restore the purification capacity of the adsorption tower.

Features:

● High adsorption efficiency: good adsorption of organic and some inorganic pollutants, can efficiently remove waste gas odor, VOCs, and heavy metal ions, pigments, etc. in wastewater, with a purification efficiency of over 80% - 90%.

● Wide range of application: It can treat all kinds of waste gas and wastewater. Regardless of the concentration of pollutants, by adjusting the amount of activated carbon and operating parameters, a good purification effect can be achieved.

●Simple operation: The equipment runs stably and is easy to operate. It does not require complex technology and professional management. Daily maintenance includes checking the equipment, monitoring the adsorption effect, and replacing/regenerating the activated carbon.

●High safety: The waste gas is mostly treated at room temperature or low temperature to avoid the risk of high-temperature combustion, and the activated carbon is flame retardant, which improves the safety of the equipment.

Application areas:

Industrial waste gas treatment, air purification, wastewater treatment, etc.
