摘要：為了解決源分離尿液腐熟效果不理想的技術問題，提出一種源分離尿液無害化處理及發(fā)酵液體有機肥的方法，進行了好氧腐熟設備的設計及樣機制作，詳細介紹了臭氧殺菌系統(tǒng)和腐熟系統(tǒng)。對源分離的尿液進行了試驗，結果表明，通過臭氧無害化處理，以微生物對尿液腐熟為基礎，實現(xiàn)了氮、磷等營養(yǎng)元素的回收，制出液態(tài)肥。

關鍵詞：源分離尿液;腐熟;臭氧;液態(tài)肥

Abstract：In order to solve technical problem that effect of source-separated urine compost was not good，a method of harmless treatment and producing liquid fertilizer of urine was proposed.The aerobic compost equipment was designed，and a production of prototype was accomplished.The parts of ozone sterilization system and compost system were introduced in detail.The urine compost experiment was carried out.Results showed that through ozone harmless treatment and urine compost by microorganisms，recovery of nutrient elements such as nitrogen and phosphorus was realized to produce liquid fertilizer.

Keywords： source-separated urine，compost，ozone，liquid fertilizer

我國城市生活污水中的主要污染物來源——尿液中含有87%的氮、50%的磷和54%的鉀，按照生態(tài)環(huán)保理論，將源分離尿液回收并最終回歸到農田是最佳途徑[1-3]。（剩余5449字）
