Yekushandisa Nyaya yeEffluent Monitoring kuSpring Manufacturing Company

Mukugadzirisa kwepamusoro pezvitubu, phosphating inoshandiswa kugadzira chidziviriro chinodzivirira chinodzivirira kuora. Izvi zvinosanganisira kunyudza zvitubu mumushonga wephosphating une maion esimbi sezinc, manganese, uye nickel. Kuburikidza nekuchinja kwemakemikari, insoluble phosphate munyu firimu inoumbwa pamusoro pechirimo.

Iyi nzira inoburitsa marudzi maviri ekutanga emvura yetsvina
1. Phosphating Waste Bath Solution: Iyo phosphating yekugezesa inoda kuchinjwa nguva nenguva, zvichiita kuti iwedzere-concentration tsvina yemvura. Zvikuru zvinosvibisa zvinosanganisira zinc, manganese, nickel, uye phosphate.
2. Phosphating Rinse Water: Kutevera phosphating, matanho akawanda ekusuka anoitwa. Kunyange zvazvo kusvibiswa kwetsvina kwakadzikira pane yekugeza kwapera, vhoriyamu yacho yakakura. Iyi mvura yekugezesa ine yakasara zinc, manganese, nickel, uye yakazara phosphorus, inoumba sosi huru yephosphating tsvina yemvura munzvimbo dzekugadzira chitubu.

Detailed Overview yeMakiyi Anosvibisa:
1. Simbi – Primary Metallic Pollutant
Kunobva: Kunyanya kunobva kune acid pickling process, uko simbi yechirimo inobatwa nehydrochloric kana sulfuric acid kubvisa iron oxide scale (ngura). Izvi zvinoguma nekuparara kwakakosha kwemaion iron mumvura ine tsvina.
Chikonzero Chekutarisa uye Kudzora:
- Visual Impact: Painobuda, ferrous ions oxidize kune ferric ions, inogadzira reddish-brown ferric hydroxide precipitates inokonzera turbidity uye kushanduka kwemavara emvura.
-Ecological Effects: Yakaunganidzwa ferric hydroxide inogona kugara panzizi, inoputira zvipenyu zvebenthic uye kukanganisa zvisikwa zvemumvura.
- Mamiriro ezvivakwa: Iron deposits inogona kutungamira mukuvharika kwepombi uye kudzikisira mashandiro ehurongwa.
- Kurapwa Kunodiwa: Pasinei nehuturu hwayo hushoma, iron inowanzovapo pakakwirira uye inogona kunyatsobviswa kuburikidza nepH kugadzirisa uye kunaya. Pretreatment kwakakosha kudzivirira kukanganisika nemaitiro ezasi.

2. Zinc uye Manganese - Iyo "Phosphating Pair"
Zvitubu: Izvi zvinhu zvinonyanya kubva kune phosphating process, iyo yakakosha pakuwedzera ngura kuramba uye kunamatira kunamatira. Vazhinji vanogadzira matsutso vanoshandisa zinc- kana manganese-based phosphating mhinduro. Mvura inotevera yekugezesa inotakura zinc uye manganese ions mumvura ine tsvina.
Chikonzero Chekutarisa uye Kudzora:
-Aquatic Toxicity: Masimbi ese ari maviri anoratidza huturu hwakakosha kuhove nezvimwe zvipenyu zvemumvura, kunyangwe pakadzika, zvichikanganisa kukura, kuberekana, uye kurarama.
- Zinc: Inokanganisa basa rehove gill, kukanganisa kufema zvakanaka.
- Manganese: Kugara kuratidzwa kunotungamira kune bioaccumulation uye inogona kuita neurotoxic mhedzisiro.
- Regulatory Compliance: Mamiriro epasi rese uye epasi rose ekuburitsa anoisa miganho yakasimba pazinc uye manganese concentration. Kubvisa kunobudirira kunoda kunaya kwemakemikari uchishandisa alkaline reagents kugadzira insoluble hydroxides.

3. Nickel - A High-Risk Heavy Metal Inoda Strict Regulation
Kwakabva
- Inherent in raw materials: Mamwe masimbi alloy, anosanganisira simbi isina tsvina, ane nickel, inonyungudika muasidhi panguva yekunhonga.
-Maitirwo ekurapa kwepamusoro: Mamwe akasarudzika emagetsi emagetsi kana machira emakemikari anosanganisira nickel makomisheni.
Chikonzero Chekutarisa uye Kudzora (Kukosha Kwakakosha):
- Hutano uye Njodzi Yezvakatipoteredza: Nickel uye mamwe nickel makomisheni anoiswa seanogona carcinogens. Ivo zvakare vanoisa njodzi nekuda kwehupfu hwavo, allergenic zvivakwa, uye kugona kwe bioaccumulation, zvichiratidza kutyisidzira kwenguva refu kune zvese hutano hwevanhu uye ecosystem.
- Mitemo Yakasimba Yekuburitsa: Mitemo yakadai se "Integrated Wastewater Discharge Standard" yakaiswa pakati pezvishoma zvinotenderwa zvekuisa nickel (kazhinji ≤0.5–1.0 mg/L), ichiratidza huwandu hwayo hwengozi.
- Matambudziko Okurapa: Kunaya kwealkali kwakajairika kunogona kusawana mazinga ekuteerera; nzira dzepamusoro dzakadai sechelating agents kana sulfide precipitation inowanzodiwa pakubvisa nickel inoshanda.

Kuyerera kwakananga kwemvura yetsvina isina kucheneswa kwaizokonzera kusvibiswa kwakasimba uye kunoramba kuchienderera kwezvakatipoteredza kwemitumbi yemvura nevhu. Naizvozvo, zvese zvinoyerera zvinofanirwa kurapwa kwakakodzera uye kuongororwa kwakasimba kuti ive nechokwadi chekuteedzera kusati kwaburitswa. Chaiyo-nguva yekutarisa panzvimbo yekuburitsa inoshanda seyero yakakosha kumabhizinesi kuti azadzise mabasa ezvakatipoteredza, kuvimbisa kutevedza kwemitemo, uye kudzikisira njodzi dzezvakatipoteredza nemutemo.
