| Abstract: | Inexpensive lime and AHZ precipitator are used to precipitate molasses alcohol wastewater. Then, a new type of water treatment agent, chlorine dioxide, is used for post-treatment. The effects of pH, CaO dosage, AHZ precipitator dosage, stirring time, etc. on the result of precipitation have been investigated preliminarily.The mechanisms of preciptation and decoloration are discussed. This method is characterized by simple process, short running period, small space, low investment. Based on the conditions given, its COD removal rate reaches 81.0%, with remarkable decoloration rate. |
