Research on control measures for excessive discharge of wastewater treatment unit
The target wastewater treatment unit adopted the method of dosing flocculation to treat wastewater,and recently there had been excessive discharge of water pollutants in the outlet system of the wastewater treatment unit.In order to improve the operational efficiency of the wastewater treatment unit,based on the analysis of the water quality indicators of the inlet and outlet systems,the influence of different types of flocculants on the wastewater treatment effect was investigated,and the composite flocculant FX-1 with better performance was selected.The long-term operational effect of the wastewater treatment unit was also examined.The results showed that the use of composite flocculant FX-1 could effectively reduce the concentrations of various pollutants in the water sample at the outlet of the target wastewater treatment unit,and the concentrations of various pollutants in the effluent system water samples could be effectively controlled within 12 months.Also,the contents of COD,suspended solids,ammonia nitrogen,total nitrogen,total phosphorus and petroleum substances could meet the"Level A standard"requirements as specified in GB 18918-2002,thus achieving the efficient and stable operation of the target wastewater treatment unit.
