Ecological method and system for treating excrement

Abstract

The invention relates to an ecological method for treating excrement. The method comprises the step of performing solid-liquid separation on the excrement to obtain waste liquid and solid waste, wherein the waste liquid is used for planting pennisetum hydridum or pennisetum purpureum after being treated by the compound microorganism preparation, and the solid waste is used for culturing the earthworms or fly maggots; the planted pennisetum hydridum or pennisetum purpureum is used for livestock or fish culture; the compound microorganism preparation is mainly prepared from 70%-80% of rhodobacter capsulatus, 5%-20% of spherical bacteria and 5%-15% of pseudomonas gelatinasa. By use of the ecologic method disclosed by the invention, the pollution on the surrounding environment by the culture industry is relieved, and the quality security of the cultured aquatic product is guaranteed at the same time; the waste liquid is treated by adding the specific microorganism preparation, the existent odor is removed, the air environment of the mountain area is beautified, and the good ecologic benefit and social benefit are provided.

Description

technical field [0001] The invention relates in particular to an ecological method and system for the treatment of excreta. Background technique [0002] In recent years, the pollution caused by livestock and poultry breeding to the ecological environment has attracted increasing attention. The first national pollution source census shows that among the main pollutant emissions in my country, COD emissions from livestock and poultry farming have accounted for 96% of the total agricultural pollution sources. , becoming the first source of pollution. The stench and harmful gas produced by livestock and poultry breeding will pollute the air, and the excrement discharged contains various pathogens, such as viruses, germs, parasites, etc., which will pollute the soil, groundwater and surface water, causing deterioration of water quality, damage to the ecological environment, and even lead to the occurrence of infectious diseases. [0003] With the rapid development of my country...

Problems solved by technology

However, in these mountainous areas, the farming technology is backward. Most of the farming industry is in the form of individual households, with extensive production methods and a low degree of scale. Simple composite three-dimensional aquaculture models are often adopted, such as "pig-fish" three-dimensional farming or "livestock farming" - Poultry-fish" three-dimensional farming, and the farming waste is often discharged directly into ponds and mountain ponds without treatment

Simple and extensive breeding methods inevitably cause ecological pressure on the surrounding environment, which not only pollutes rivers and water sources, but also affects the quality and safety of farmed aquatic products, and the malodorous gas produced by simply treated excrement has a negative impact on the surrounding environment. It also causes pollution, and the task of protecting water sources is arduous
