Abstract:

The water quality standard of circulating supplementary water is used as the treatment requirement of effluent purification.In the process of purification,the ash washing water in the power plant is introduced as co-agulant aids.The treatment result is thus improved.Then,scale and corrosion inhibition experiments have been done by using purified effluent.A suitable prescription is chosen.The aim of the reuse of effluent is so realized,the effluent discharge in the power plant is basically zero.

Key words: flocculation-sedimentation, power plant wastewater, circulating water, zero-discharge

摘要：

以电厂循环冷却水系统补充水水质标准,作为对电厂污水净化处理的要求,在净化处理中引入电厂冲灰水作为助凝剂,提高了处理效果,然后用净化后的污水做阻垢缓蚀试验,筛选出合适的配方,达到污水回用的目的,使电厂污水基本达到零排放。
