集約化豬場糞污處理工藝的研究

摘要: 根據我國集約化豬場排糞方式和糞水的特性,提出了采用人工清糞方式 、固液分離機+沉淀+UASB+SBR+水生植物塘的污水處理工藝和豬糞(渣)堆漚發酵生產有機 肥新的糞污處理工藝。經上海市嘉定種畜場污水處理工程實踐證明:在保證污水全面達標排 放和豬糞(渣)無害化處理的前提下,新工藝比常規工藝節約工程投資35%、節約運行電費6 5%左右,經濟效益好 Abstract: In accordance with the characteristics of swine manure-discha rging way and the property of swine wastewater on intensive scaled swine farms i n China, a new technology of swine wastewater treatment and swine manure ferment ation to produce organic fertilizer was presented. This technology includes clea ning manure by manpower, solid-liquid separator+sedimentation basin+Upper-flow Anaerobic Sewage Bed(UASB)+SBR+aquatic plant pond. The project practice of swin e wastewater treatment in Shan ghai Jiading Breeder Farm showed that the new technology could save 35% of the p roject investment, 65% of the operating electricity charges with good direct eco nomic benefit, on condition of guaranteeing the prerequisites that the discharge d swine wastewater reached the state standard all-sidedly and swine manure was pollutionlessly treated. 作 者: 李長生    王應寬    LI Changsheng    Wang Yingkuan   作者單位: 中國農業工程設計研究院,  期 刊: 農業工程學報  ISTICEIPKU   Journal: TRANSACTIONS OF THE CHINESE SOCIETY OF AGRICULTURAL ENGINEERING  年,卷(期): 2001, 17(1)  分類號: X713  關鍵詞: 豬糞處理    固液分離    沉淀    厭氧池    好氧池    堆漚發酵
