摘要

沸石在强化A/O生物脱氮效果的同时改善了污泥的脱水性能。含沸石污泥的比阻随沸石含量的增加而降低,当沸石质量浓度在4g/L时,污泥脱水后体积变化梯度大。综合比较表明,含沸石污泥不投加混凝剂而直接脱水是适宜的。

Abstract

While enhancing the effect of bio-denitrification,zeolite improves the dewatering capability of sludge.Whether flocculant are thrown into or not,the specific resistance of sludge will decrease remarkably with the increasing of zeolite concentration in sludge.When concentration of zeolite in the sludge is 4 g/L,the volume change of filter cake is the biggest after the sludge dewatering. Comprehensive evaluation shows that the sludge of containing zeolite dewater directly is economic.
