High-concentration wastewater and special wastewater can enter the wastewater treatment project after being pretreated in the workshop according to the water quality:
1. Special wastewater containing active ingredients of antibiotic drugs, biological toxicity or ecological risks shall be pretreated separately in accordance with the regulations of relevant departments
2. For high ammonia nitrogen wastewater, one or a combination of several processes such as steam stripping, evaporation, and air stripping should be selected
3. For wastewater containing refractory organic matter, pretreatment processes such as chemical oxidation, iron-carbon micro-electrolysis, and rectification should be adopted
4. For high-concentration organic wastewater, processes such as rectification, physical stratification, and incineration should be selected
5. For high-salt wastewater, desalination methods such as evaporation should be adopted
