The choice of process flow for dairy wastewater treatment depends on the characteristics of the wastewater and the effluent discharge requirements. The treatment process is primarily biological, and based on the main unit responsible for pollutant removal load, it can be divided into aerobic treatment systems and “anaerobic + aerobic”
In Wastewater treatment, common processes include physical methods, chemical methods, and biological methods. They have different usage objects and effect. Today we will first discuss physics method. The physical method mainly uses physical means to remove suspended solids, floating solids, and some dissolved substances in sewage, without changing the chemical
2. Classification of electroplating wastewater based on pollutant composition and process linksIt can be mainly divided into three categories. 1). Chromium-containing wastewater: mainly hexavalent chromium (Cr⁶⁺), which is highly toxic and carcinogenic. It needs to be converted into low-toxic trivalent chromium (Cr³⁺) through chemical reduction (such as sodium sulfite), and
