摘要

采用自行设计的浸没式膜生物反应器(Submerged Membrane Bioreactor

SMBR)处理模拟生活污水

研究污泥负荷Ns

曝气量及pH值等运行参数对反应器混合液中胞外聚合物(Extracellular PolymericSubstances

EPS)及污泥特性的影响

并对EPS与污泥特性的相关性进行了探讨分析.研究结果表明:污泥负荷或曝气量的提高会降低EPS总量以及多糖的含量

pH值的提高会同时提高多糖以及蛋白质的含量;EPS与Zeta电位存在正相关性

相关系数R20.97;以pH值为运行参数时

pH值对污泥特性的表征性优于EPS.

Abstract

Submerged membrane bioreactor(SMBR) was used to treat domestic wastewater.The influences of operation conditions(sludge burthen

aeration

pH value

etc) on the extracellular polymeric substances(EPS) and sludge properties in the reactor were investigated respectively

and the relation between EPS and sludge properties were discussed.The experiment results showed that EPS and amylase will decrease as burthen Ns or aeration increases

and amylose and protein sludge will increase as pH value increases.There was positive correlation between Zeta potential and EPS

with correlation coefficient R20.97;pH was a better operation parameter than EPS to indicate the sludge properties.
