- Abstract:
- To improve the environmental treatment level of chemical industrial park, a professional wastewater treatment plant was built to treat chemical wastewater in a chemical industrial park in Taihu basin. Chemical wastewater from all enterprises in the park is collected through “one enterprise one pipe and open channel or special pipe transportation” and discharged to the wastewater treatment plant, and treated based on the principle of “classified collection and treatment”. The design scale of the wastewater treatment plant is 1.0×104 m3/d. The organic chemical wastewater is treated by the combined process of regulating homogenization, hydrolytic acidification, AO biochemical process, Fenton oxidation, high efficient precipitation and activated carbon in-situ adsorption and desorption, while the inorganic chemical wastewater is treated by the process of regulating homogenization and high efficient precipitation. The effluent quality stably meets the limit specified in Discharge Standard of Main Water Pollutants for Municipal Wastewater Treatment Plant & Key Industries of Taihu Area (DB 32/1072-2018) and Discharge Standard of Water Pollutants for Chemical Industry (DB 32/939-2020). The average wastewater treatment cost is approximately 8.466 yuan/m3.
