This article reviews the formative mechanism and influential factors of beer colority, as well as the improvement of technological measures. 現(xiàn)對啤酒色度的形成機(jī)理，影響啤酒色澤形成的因素及改進(jìn)啤酒色澤的工藝措施作一論述。
The most important parameters of wastewater such as COD, colority, turbidity etc, could be decreased efficiently by one step of coagulation. 經(jīng)過一步強(qiáng)化混凝處理后，各種廢水的COD、 色度和濁度等均有良好的去除效果。
The results indicate that the pretreatment process can improve biodegradability of the wastewater and reduce COD and colority, resulting in the benefit to the follow-up biological treatment. 采用鐵屑過濾法預(yù)處理可生化性差的印染廢水，能改善廢水的可生化性，降低廢水的COD和色度，有利于后續(xù)生化處理。
