当前农村在普遍搞厕所、畜圈和沼气“三合一”沼气池。几年来对各种形式的沼气池的卫生学研究表明由于长时间大量沉积结果,池渣含虫卵密度大,且大都为活卵,若不经化学、物理方法处理而施用于菜地、薯地,势必造成大量寄生虫的感染。一九七六年我们曾在莆田石码大队对施用沼气池渣的薯地作钩蚴分离,分离五块,每块分离2500克,平均每块分离到钩蚴117条。因此,如何经济有效地处理沼气池粪渣使之无害化是当前国内沼气卫生科研重要课题之一。
The current rural areas are generally engaged in toilet, livestock and biogas “triple” digesters. Several years of biogas digester hygiene studies have shown that due to the large number of deposition results for a long time, the pond residue containing eggs with large density, and most of the live eggs, if not by chemical and physical treatment applied to the vegetable, potato Ground, is bound to cause a large number of parasitic infections. In 1976, we once separated the rock masses of biogas residue residue in the potato brigade of Putian, separated five pieces of 2500g each and separated 117 pieces of oncosphere. Therefore, how to deal with the digester dregs harmlessly economically and effectively is one of the important topics of domestic biogas health research.
