Treating the galvanization wastewater by complex process

Tong Zhen-Gong

Treating theGalvanizationwastewater byComplex processwhich includes chlorine dioxide coordination oxidant broken cyanogens process, iron filings internal electrolysis degraded the chromic wastewater and alkalinity precipitation method processed comprehensive wastewater. The water quality of the treated wastewater reached the request of the Integrated wastewater discharge standard (GB8978-1996). The paper described this engineering fromfollowing aspects includingwater quality andwater quantity, treatment processes, flow explain, main buildings, investment and operation cost. The paper has certain guides for the same type wastewater treatment.
