碳中和背景下碳源捕获的污泥厌氧发酵性能
Performance of Carbon Source Capture for Sludge Anaerobic Fermentation under the Background of Carbon Neutral
摘要
Abstract
Under the concept of carbon neutral and sustainable development,and autotrophic biological nitrogen removal process requires the ideal influent water quality requirements of low carbon and high nitrogen,the high efficiency carbon source capture technology of municipal domestic wastewater has been developed rapidly.This paper studies the anaerobic fermentation performance of the carbon source sludge captured by this technology.Results showed that the SCODCr degradation rate of dissolved organic matter,volatile suspended solid(VSS)and total phosphorus(TP)mass concentration in anaerobic fermentation were about 77.70%,15.26%and(1.35±0.18)mg/L,respectively.In addition,the average cumulative gas production of captured carbon source sludge could reach 31.43 mL/(g VSS)and 709.54 mL/(g SCODCr).At the same time,through three-dimensional fluorescence spectrum,it was found that anaerobic sludge could directly use the carbon source of captured carbon source sludge for fermentation.Compared with the control group,captured carbon source sludge had the advantages of rapid fermentation,efficient gas production and sludge reduction and stabilization.It provides a new idea for the treatment and resource utilization of carbon capture source sludge produced in autotrophic biological nitrogen removal process.关键词
