摘要

通过小试试验研究PTA废水处理污泥生物减量效果及影响因子，结果表明，一次性进料、设备温度60℃、菌剂占污泥干基比例4%，可实现污泥含水率、干物质和毒性物质（钴）分别减少79%、22%和9%的最佳减量效果.基于污泥生物减量过程中多参数、三维荧光和微生物属水平变化并结合相关和主成分分析，探明了影响PTA污泥生物减量的关键因子分别为温度、电导率、胡富比、碳氮比、溶解性有机碳和8种微生物菌属（即为Gemmatimonas、Pelotomaculum、Azohydromonas、Pseudomonas、Paeniglutamicibacter、Weissella、Nitrospira、Novosphingobium）.研究结果可为化纤厂PTA污泥生物减量提供科学依据.

Abstract

In this study, microbial reduction method was used to determine the optimal reduction effect. The results showed that under the condition of one-time feeding, equipment temperature controlled at 60℃ and the dosage of microbial agent accounted for 4% of the dry weight of sludge, the optimal reduction effect was:the water, dry matter and toxic substances (i.e. Co) reduction rate reached 79.4%, 22%, and 9%, respectivity. Based on correlation analysis and principal component analysis, temperature, electrical conductivity, humic/fulvic acid ratio, carbon/nitrogen ratio and dissolved organic carbon, as well as 8genera (i.e. Novosphingobium, Nitrospira, Azohydromonas, Gemmatimonas, Pseudomonas, Pelotomaculum, Paeniglutamicibacter and Weissella) were determined as the key factors affecting the bio-reduction effect. The research results provide a scientific basis for the bio-reduction ofPTA sewage sludge in chemical fiber plants.
