Background

In the beginning of the 21 st century, the Ministry of agriculture proposes ecological home construction, adopts a 'three-in-one' mode to construct a biogas toilet, and constructs a household biogas device by constructing a livestock and poultry colony house, the toilet and a biogas pool on the ground and constructing a biogas pool underground, so that biogas is generated to serve as fuel for farmers to use, develop rural energy, promote the coordinated development of rural planting and breeding industry, and solve the dirty, messy and poor human-living environment appearance of rural areas; the construction of rural biogas projects and the synchronous construction of toilet modification, circle modification and kitchen modification, namely 'one pool and three modifications', and the construction of vast rural areas by 'one pool and three modifications' basically changes the original conditions of open toilet, open colony house and kitchen sooting and singing, and realizes the scene of 'cooking by lighting biogas and no cooking smoke in rural areas'; the planting and breeding cooperative development is promoted, and the living environment of the rural area is improved to a certain extent.

Along with the requirements of three major revolutionary generations of rural garbage, sewage and toilet for ecological civilization construction proposed by party centers and state offices, the original toilet modification standard is far from the requirement of the 'toilet revolution' in the ecological civilization construction, and the requirements of rural human living environment under the ecological civilization construction cannot be met; therefore, the water flushing toilet is newly built in rural areas, and human excrement and urine are collected to a village-level sewage treatment system for centralized treatment.

However, in order to improve the resource utilization of human and animal urine and feces in the rural water flush toilet, if a dry toilet communicated with a methane tank is transformed into the water flush toilet, a large amount of flushing water enters the methane tank, the methane tank is filled in a short period of time, the existing methane device needs to manually extract methane liquid and methane slag from the methane tank for fertilization, and the frequency of extracting the methane liquid needs to be improved when a large amount of flushing water enters the methane tank, but because of the lack of labor in rural areas, the removal of the methane liquid and the methane slag by individual households is difficult, and the rural water flush toilet is very inconvenient for farmers to use.

In view of this, the utility model is especially provided.
