- Abstract:
- The wastewater from Mianyang high-end manufacturing industry concentrated development area contains high concentration of fluorine and refractory organic matter, and there are high requirements for nitrogen, phosphorus and SS treatment. In Wujia industrial wastewater treatment plant, a combined process consisting of heteronuclear crystallization coagulation precipitation, adsorption and ion exchange was employed to treat the fluorine containing wastewater separately, and then combined with other wastewater to be treated by a process consisting of hydrolytic acidification, multi-stage A/O, high efficiency precipitation, deep bed filter and ozone contact reactor. The stepwise treatment of different wastewater saved the operating cost, optimized the process layout, with advanced technology and high degree of intensification. The design scale of the project is 4×104 m3/d. When the actual average treatment scale of the comprehensive wastewater was 35 520 m3/d, the pollutant concentration in the effluent was lower than the discharge standard. The direct operating cost of the project is 4.2 yuan/m3.
