Method for solid-liquid separation of liquid manure and fertilizer making with manures and special vehicle

Abstract

The invention discloses a method for solid-liquid separation of liquid manure and fertilizer making with manures and a special vehicle. Particularly, at a position close to a toilet septic tank, solid-liquid separation of the liquid manure in the toilet septic tank is performed, the septic tank is dredged, solid manure is collected, and the collected solid manure is fermented to produce organic fertilizers, so that innocent treatment and resource utilization of the liquid manure are achieved. The invention further discloses the special vehicle for implementing the method.

Description

technical field [0001] The present invention relates to a method for solid-liquid separation of excrement and water, and a method for producing fertilizer from excrement, and a special vehicle; specifically, a special vehicle equipped with solid-water separation equipment for excrement and water and a device for fermenting fertilizer from excrement is used to turn toilets into feces The method for solid-liquid separation of excrement in a pool, and then making the separated solid excrement into organic fertilizer belongs to the field of environmental protection technical equipment. Background technique [0002] At present, residential quarters in cities and towns in China are equipped with public toilets and septic tanks. The surface of the feces in the septic tanks often agglomerates. At present, the feces in the septic tanks of public toilets in large and medium-sized cities mainly rely on traditional fecal suction trucks to regularly pump out the feces, and transport the ...

[0002] At present, residential quarters in cities and towns in China are equipped with public toilets and septic tanks. The surface of the feces in the septic tanks often agglomerates. At present, the feces in the septic tanks of public toilets in large and medium-sized cities mainly rely on traditional fecal suction trucks to regularly pump out the feces, and transport the feces to the sewage treatment plants on the outskirts of the city for harmless treatment. treatment; if the solid feces are separated from the feces, it can effectively reduce the percentage of organic matter in the feces, which is conducive to reducing the cost of sewage treatment plants for the purification of feces; some urban and rural toilet septic tanks are collected after excrement The feces are not treated, but landfilled or discharged anywhere, which seriously pollutes the environment; the feces water contains a large number of parasites, germs, and harmful substances, and the odor pollutes the environment. In particular, the feces produce odor and "run, The phenomenon of "floor leakage" has caused serious pollution to the environment; transporting urban manure to sewage treatment plants on the outskirts of the city will increase a lot of transportation costs; in particular, transforming human manure into high-quality pollution-free organic fertilizers It is of great significance to develop vegetables or crops in ecological agriculture, reduce the market supply of synthetic fertilizers, promote and strengthen the ecological cultivation of vegetables or the development of ecological agriculture, and improve the economic benefits of toilet septic tank treatment

[0003] There have been many reports on the car for manure water treatment, and the inventor disclosed in the authorized announcement number CN203438914 U "Integrated Manure Water Purification and Treatment Car" that "separate the feces solids in the manure water from the waste water, and the waste water purification standard treatment and the feces There are three functions such as storage and transportation; however, the general towns do not have special excrement harmless treatment plants, and generally they can only be filled with feces, which seriously pollutes the surrounding environment and groundwater; Pollution of the atmospheric environment; this is the serious defect of the existing public "Integrated Feces and Water Purification Vehicle";

[0004] By searching and consulting a large number of documents, magazines, books, CD-ROMs, patents, ... and other materials at home and abroad, no method and special-purpose method for implementing "solid-liquid separation of excrement and liquid and excrement to prepare fertilizer" near the toilet septic tank has been found at home and abroad.
