调理剂投配比及粒径对污泥堆肥的影响研究
Study of effects of amount and particle size of new conditioner on sludge composting
摘要
Abstract
Sewage sludge and new recyclable LWK conditioner were composted to investigate the effects of the amount and the particle size of the new conditioner on the fermentation effi-ciency and nitrogen loss .The variation of temperature , respiration rate , organic content (VS), dissolved organic carbon (DOC), ammonia volatilization rate, nitrogen content and pH was determined during 25 days composting .The result showed that the production rate of CO2 reached a maximum of 12.44 mg/( kg· VS· d)for the test group(msludge∶mconditioner =1∶0.8).Three particle sizes conditioners (21,30,40 mm) were used in the sludge compost. The conditioner of 30 mm diameter reached a maximum temperature of 42 ℃.The nitrogen loss rates of the three group were 15.73%,6.90%,13.19%respectively.Using the condi-tioner at average particle size of 30 mm could reduce nitrogen loss obviously .关键词
