The basic principles of industrial wastewater treatment (a) preferred non-toxic manufacturing process or reform instead of backward production technology to produce as much as possible in the production process or reduce toxic and hazardous wastewater. (B) the use of toxic materials and toxic intermediates and products in the process, should be strictly operation, eliminating toxic substances reduce drip loss, as far as possible and reasonable processes and equipment. (C) waste water containing toxic substances such as heavy metals contain radioactive substances, high concentrations of phenol, cyanide for processing and recovery of useful substances. (D) the larger flow and less contaminated wastewater should be treated properly recycled, the city should not be discharged into the sewer plus sewer and urban sewage processing load. Similar urban sewage organic waste, such as food processing waste water, sugar water, paper waste can be discharged into the municipal sewage system for processing. (E) some biodegradable toxic waste, such as phenol, cyanide waste, should be treated, according to the allowable emission standards into city sewers, further biological treatment. (Vi) difficulties biodegradable toxic waste should be treated separately and should not be discharged into the city sewer. Development trend of industrial wastewater treatment is to waste water and pollutants as a useful resource or implement closed loop recycling. (Seven) hard-biodegradable toxic waste should be treated separately and should not be discharged into the city sewer. Development trend of industrial wastewater treatment is to waste water and pollutants as a useful resource or implement closed loop recycling. Guangzhou Fu students focused on environmental Xingtan dyeing wastewater treatment works (3600m3 / d): Water in the power industry and chemical industry uses are many, including boiler feed water, chemical process water, cooling water and so on. Today, power plants and chemical plants toward high-capacity, high-parameter development of industrial wastewater, water quality is also growing, so in addition to conventional coagulation, sedimentation, filtration and other treatment methods outside the electroplating wastewater, the need to ion exchange, RO, EDI and other pure water desalination technology. Guangzhou Fu students focused on environmental Xingtan dyeing wastewater treatment works (3600m3 / d): high-pressure boiler feed not only requires low hardness industrial wastewater recycling, the amount of dissolved oxygen is minimal, and organic content of the solids content is minimal, did not meet the water standard water will make the plant safe and economic operation of the device can not need reverse osmosis desalination water treatment systems, rehabilitation beds, mixed bed ion exchange high purity water systems ultrapure water treatment equipment to handle pressure boiler feed water plant. To this end has developed a variety of water quality indicators of thermal power plants. IPC programmable control system control, automatic start and stop, dosing and flushing, automatic monitoring of various operating parameters for production management.
