"【XJY Environmental Tekinoroji】 Kuongorora kwakazara kwepakati-saizi yekuchenesa tsvina yemumba: gwara rakazara kubva kunobva kune inogadziriswa mhinduro"

Medium-Scale Domestic Wastewater Treatment 1. Mhando Dzemvura Yetsvina: - Mvura Yetsvina Mudzimba: Inobva mudzimba, kusanganisira zvimbuzi, singi, mashawa nekuwacha. -Kutengesera Mvura Yakasviba: Inogadzirwa nenzvimbo dzekutandarira, mahotera nemaresitorendi, uko kugadzirira kwechikafu uye sevhisi yevaenzi inogona kuve sosi yekuwedzera marara uye makemikari. -Indasitiri Wastewater: Kazhinji inouya kubva kumaitiro ekugadzira uye inogona kuve neakasiyana mazinga ezvinosvibisa zvinoenderana neindasitiri. 2. Wastewater Characteristics: - Organic Matter: Zvizhinji zvinogona kubva mumarara ezvokudya, detergents uye tsvina yevanhu. - Nutrients: Nitrogen uye phosphorus mazinga anogona kukwidziridzwa, achida kurapwa kudzivirira algae maruva mukugamuchira mvura. - Kemikari Inosvibisa: Zvichienderana nemupiro weindasitiri, simbi inorema, oiri uye mamwe makemikari anogona kunge aripo. 3. Kurapa Maitiro: - Yekutanga Kurapa: Kuongorora uye kusvibisa kubvisa marara akakura uye zvinyoro zvinogadziriswa. - Yekutanga Kurapa: Sedimentation matangi anobvisa yakamiswa yakasimba uye kuderedza BOD (biochemical oxygen kudiwa). -Kurapwa kwechipiri: Biological process senge activated sludge kana biofilm reactors inogona kuwedzera kudzikisa organic zvinhu uye zvinovaka muviri. Izvi zvinogona kusanganisira zvose aerobic uye anaerobic maitiro. -Kurapwa kwepamusoro: Nzira dzepamusoro dzekurapa dzakadai sekusefa, kuuraya utachiona (chlorination kana UV), uye kubviswa kwezvikafu zvinova nechokwadi chekubuda kwemhando yepamusoro. 4. Zvinetso: - Kuyerera kusinganzwisisike: Kusiyana kwemitengo yekugara mumahotera kana vashanyi vemwaka zvinogona kukonzera kuyerera kwekufamba, zvichiita kuti kurapwa kurambe kuchinetsa. -Kusiyana-siyana kunosvibisa: Zvivako zvakasiyana zvinogona kuburitsa zvinosvibisa zvakasarudzika, zvinoda inochinjika uye inochinjika kurapwa mhinduro. - Mitemo: Kutevedzera mirairo yenharaunda yezvakatipoteredza maererano nekuyerera kwemvura yetsvina kunogona kuve kwakaoma, kunyanya kana mvura yetsvina yemumba neyemaindasitiri yakasanganiswa. 5. Maitiro akasimba: - Kudzokorodza mvura: Kuita masisitimu anoshandisa zvakare tsvina yakacheneswa pakudiridza kana kugezesa muchimbuzi kunogona kubatsira kuderedza kudiwa kwemvura kwese. - Zvivako zvakasvibirira: Kushandisa masisitimu ekurapa echisikigo senge matoro akavakwa anogona kuwedzera kurapa kwakanaka uye kutsigira zvipenyu. - Kubatanidzwa kwenharaunda: Kubatanidza vagari venzvimbo uye mabhizinesi mukuedza kuchengetedza mvura kunogona kuwedzera kushanda kwemaitiro ekugadzirisa mvura yetsvina.

Mhedziso Kubudirira kwekutonga kwemvura yetsvina mumasisitimu emvura yetsvina yemudzimba, kunyanya munzvimbo dzakasanganiswa-sekushandisa senge nzvimbo dzekutandarira nenzvimbo dzekugara, kwakakosha kuchengetedza hutano hweveruzhinji uye nharaunda. Nzira yakabatanidzwa inoshandisa tekinoroji yakakodzera yekurapa uye inosimbisa kugadzikana inogona kubatsira kugadzirisa matambudziko akasiyana anounzwa neaya akasiyana masosi emvura.
