当今印染废水治理述评

Review of Wastewater Treatment Nowdays Dye—printing Industry

本文强调了印染废水治理应该重视中间控制。在终端处理方面,则重点评述了在当今印染废水可生化降解性越来越差的情况下,从环境效益,经济效益两方面考虑,印染废水治理仍应优先选用生物法;并重视化学混凝法的合理应用;要实现废水回用可采用活性炭吸附等三级处理工艺。

The article emphasizes that it should be paid great attention to reducing the amount of contaminator produced in the production process and it emphatically summarizes the various dye-printing wastewateu processes.Environmental and economic benefit considered,it should be taken precedence over the others dealing with dye-printing wastewater by biochemical process,even though the biodegradability of nowdays dye-printing wastewater gets worse and worse.And it should be paid attention to appling coagul rationally.The dye-printing wastewater dealed with by activated carbon adsorption or other third wastewater treatment processes.
