Process for urban fecal treatment using engineering earthworm

Abstract

The present invention relates to environment science and technology, and is especially biotechnological process of treating excrement from city. The technological process includes treating excrementin fermenting pond, producing feed medium with excrement and soil, setting feed medium in culture plate, setting fermented organic matter to the surface of the culture plate, separating mature earthworm, young earthworm, earthworm egg from the earthworm dung, feeding mature earthworm to processing area for making high-protein feed and producing medicine, producing organic fertilizer with earthworm dung, and backing young earthworm and earthworm egg to culture plate. The present invention is one high-utility green engineering.

Description

Technical field:

[0001] The invention relates to an environmental science and technology, in particular to a method for treating urban excrement by utilizing biotechnology. Background technique:

[0002] In the world, there are currently only a few countries that use earthworms to treat urban waste and sewage treatment technology, and there is no system that uses earthworms to treat urban excrement. Urban excrement is a considerable renewable resource. According to the degree of modernization, countries in the world are not the same. Some advanced countries use water-washing toilets, and all excrement is discharged into the sewer and enters the adjacent rivers, rivers, lakes and seas. Underdeveloped countries have to build most of the dry toilets, and if there are dry toilets, they must build excrement discharge sites. However, whether it is a dry toilet excrement discharge site or a wash toilet, it is the source of polluting the environment and polluting the surface water....
