Iyo neutralization yekurapa tekinoroji yeasidhi yekugeza mvura yetsvina inhanho yakakosha mukubvisa zvinhu zvine acidic kubva mumvura yetsvina. Iyo inonyanya kushandura zvinhu zvine acidic kuita zvinhu zvisina kwazvakarerekera kuburikidza nekuita kwemakemikari, nekudaro kuderedza kukuvadza kwavo kune zvakatipoteredza.

1. Neutralization musimboti: Neutralization reaction ikemikari inoitwa pakati peasidhi nealkali, ichigadzira munyu nemvura. Acid yekugeza tsvina mvura inowanzo ine yakasimba asidhi yakadai sesulfuric acid uye hydrochloric acid. Panguva yekurapa, huwandu hwakakodzera hwezvinhu zvealkaline (zvakadai sesodium hydroxide, calcium hydroxide, kana lime) inoda kuwedzerwa kuti isaite izvi zvinoumba acidic. Mushure mekuita, iyo pH kukosha kwemvura yakasviba ichagadziriswa kune yakachengeteka renji (kazhinji 6.5-8.5).

2. Kusarudzwa kwemaitiro ekugadzirisa zvinhu: Kazhinji neutralizing agents zvinosanganisira sodium hydroxide (caustic soda), calcium hydroxide (lime), etc. Aya ma neutralizing agents ane reactivity yakanaka uye hupfumi. Sodium hydroxide inobata nekukurumidza, asi kunyatsoshanda kunodiwa kudzivirira furo rakawandisa uye kuputika; Calcium hydroxide inobata zvishoma nezvishoma, asi inogona kuumba mvura mushure mekurapwa, iyo yakanakira kubviswa kunotevera.

3. Kudzora kwekuita neutralization process: Panguva yekusagadzikana kwemaitiro, zvakakosha kutarisa pH kukosha kwemvura yakasvibiswa munguva chaiyo kuti ive nechokwadi cheyakakodzera acid-base ratio. Iko kushandiswa kweiyo otomatiki yekudzora sisitimu inogona kuwana chaiyo dosing uye kudzivirira mamiriro ekuwedzeredza kana kushomeka. Uye zvakare, kupisa kuchaburitswa panguva yekuita maitiro, uye zvakakodzera maitiro midziyo inofanirwa kutariswa kudzivirira kupisa kwakanyanya.

4. Kurapwa kunotevera: Mushure mekusaurura, mvura yetsvina inogona kunge iine yakaturikwa yakasimba uye heavy metal ions. Panguva ino, dzimwe nzira dzekurapa dzakaita sedimentation uye kusefa dzinoda kubatanidzwa kuti dziwedzere kubvisa zvinosvibisa zvakasara uye kuve nechokwadi chekuti hunhu hwemvura hunosangana nemamiriro ekunze.

Kuburikidza neanoshanda neutralization yekurapa tekinoroji, asidhi yekugeza mvura yetsvina inogona kurapwa zvakachengeteka, ichideredza kukanganisa kwayo kwezvakatipoteredza uye kusimudzira kusimudzira kwakasimba kwekugadzirwa kwemaindasitiri.
