摘要:
采用KMnO4或微波单独及联合作用预处理剩余污泥。通过对比破解前后污泥上清液中混合液挥发性悬浮固体浓度/混合液悬浮固体浓度(MLVSS/MLSS)、污泥体积指数(SVI)、污泥破解率(DD)、溶解性蛋白质含量、溶解性多糖含量、含固率等变化,考察KMnO4或微波单独及联合作用对污泥破解以及污泥特性的影响。结果表明:KMnO4-微波联合作用相比于单独使用KMnO4或者微波效果更好,可以进一步提高污泥的破解率,增大有机物的溶出量,影响因素的主次顺序为微波功率、反应时间、KMnO4投加量。采用联合作用的最佳处理条件为微波功率800 W,反应时间240 s,KMnO4投加量2 000 mg/L,此时蛋白质和多糖在上清液中的质量浓度分别为229.46 和258.47 mg/L。
Abstract:
The sludge disintegration and characteristics under the treatment of KMnO4, microwave as well as their combined form were investigated by comparing the variation of mixture volatile suspension solid concentration/mixture suspension solid concentration(MLVSS/MLSS), sludge volume index(SVI), sludge disintegration degree(DD), soluble protein, soluble polysaccharide and solid containing rate before and after disintegration. Results showed that the combined treatment of and KMnO4 and microwave could further improve the cracking rate of sludge and increase the dissolution rate of organic matter.The factors that affected the rate were in the order of microwave power, reaction time, and KMnO4 dosage. The optimal treatment effect was obtained with the microwave power of 800 W, the reaction time of 240 s, and KMnO4 dosage of 2 000 mg/L. The mass contents of protein and polysaccharide were 229.46 and 258.47 mg/L, respectively.
