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.
