1、摘要本文就陶瓷废水的产生来源及废水处理原理进行了分析 ,对佛山市该行业废水处理常用的固液分离方式进行了处理效果及技术经济比较 ,指出将常用于给水处理工艺的水力循环澄清池应用在陶瓷废水处理工艺中,与其它分离方法相比,不仅占地面积小,效率高,而且易于操作和控制,可实现废水的全部回用,并建议对这种高悬浮物、高浊度水的混凝反应过程进行自动控制以提高水处理的稳定性。最主要的污染因子便是悬浮物(SS) ,因此只要对SS 进行有效削减,其余各污染因子浓度便能随之被控制在排放标准之内,实际上是对含高悬浮物高浊度水的处理。本设计的目的就是通过对聚合氯化铝(PAC)的合成,及对其进行改性,使其对陶瓷废水具有良好絮
2、凝作用。 本设计采用以混凝沉淀为主的综合处理工艺处理陶瓷生产废水和生活污水具有工艺简单、技术成熟、易控制、启动运行方便、处理效果好等优点。针对废水的水质及污染物的特征,在工艺设计及运行控制方面采取的技术改进措施使整体工艺的高教运行成为可能。关键词 陶瓷废水 固液分离 水力循环澄清池 混凝自控Abstract The resource of wastewater from ceramics and the treating principle of the wastewater are analyzed; and a comparison of the treated result and te
3、chnical economy by the common solid-liquid separation method for treating wastewater in Fushan City is conducted. It is indicated that when combining hydropower circulation clarifier with the treating process of wastewater from ceramics, which features not only small area , high efficiency , but als
4、o easy operation and control with 100 % recovery of wastewater as compared to other separation methods.It is suggested that a self-control should be usedfor the coagulating reactionof wastewater of high suspension and turbidity in order to raise the stability of wastewater treatment.

Actually, to reduce the high consistency of SS is the majior treatment. This design is using the PAC to precipit
