江西省规模化养殖场调查及沼液理化性质研究

摘要

Aiming at a series of rural environmental pollution problems of the fecal pollution treatment in large-scale farms, taking 8 large-scale farms and field biogas projects in Jiangxi Province as research object, the basic information of farms and biogas projects were obtained, and the atmospheric environment in the farms was monitored.Meanwhile,samples of feed pool, fermenting tank and biogas liquid pool were collected, and the physical and chemical properties of the collected material were detected and analyzed.The results showed that:biogas engi-neering design and construction specifications and facilities were relatively complete,mainly using livestock and poultry manure as raw materi-als, but the feed material TS400, >800 and >1 400 mg/L,respectively,the nutrient content is still very high.The results can provide a ref-erence for the healthy operation and development of large-scale farms and biogas engineering.%针对规模化养殖场粪污处理等一系列农村环境污染问题,以江西省8家规模化养殖场及场内沼气工程为研究对象,获取各养殖场及沼气工程的基本信息,并对养殖场内大气环境进行了监测.同时,采集进料池、发酵罐和沼液池料液样品,对所采集料液的理化特性进行检测和分析.结果表明:沼气工程设计施工规范,配套设施较齐全,主要以畜禽粪便为原料,但进料料液总固体(TS)400、>800和>1400 mg/L,养分含量仍然非常高.该调查结果可为规模化养殖场及沼气工程的健康运行与发展提供参考.
