China. Hence the aforesaid wastewater has given a great effect to environmental security. Although a lot of organic pollutant and parts of CN- ions could be removed from this wastewater by anaerobic biological process, yet the cyanogen content in the effluent of the treated wastewater is still much higher than the national drainage standard. It is necessary to use the method of closed management for the final effluent of this wastewater to be treated in a stabilization pond. 收起<<
