摘要
污水处理厂实际进水指标高于设计值,且设备老化等导致出水水质达标率逐年递减,考虑场地有限,故尽量利用原有构筑物及设施,对预处理系统、二级生化处理系统、加药系统等单元进行技术改造,确保出水水质稳定达标,水厂稳定运行。
The actual water inflow index of sewage treatment plant is higher than the design value, and the aging rate of the effluent water is declining year by year. Considering the limited space, it is necessary to use the original structure and facilities, the pretreatment system, the secondary biochemical treatment system, The dosing system and other units carry out technical transformation to ensure that the effluent water quality is stable and the water plant is stable.
