And compared with the prior rural areas, the residential community has obviously concentrated living modes, although the residential community is still relatively dispersed compared with the urban area. The condition ensures that the residential community does not have enough natural resources to purify sewage, and if the sewage is not treated, the pollution of rivers and ponds can be caused, the surrounding water environment is deteriorated, and even certain threat is caused to the health of residents; but also makes the domestic sewage of the residential community difficult to collect and treat in a centralized way like a town.
At present, the residential communities usually adopt various families to build methane tanks to treat domestic sewage, the treatment method is high in cost and uneconomical, the specifications of the methane tanks are not uniform, the position distribution is scattered, the occupied area is too large, and potential safety hazards are easily caused. Moreover, the capacity of the biogas digester is small, and the main function is septic treatment, so that a lot of domestic wastewater with low pollution at that time is directly discharged by community residents without treatment, and the community of the residents is caused to be full of foul smell in the past, so that the biogas digester is necessary to provide an integrated sewage treatment device which meets the requirements of rural domestic sewage treatment, does not need a biological treatment method with chemical agents, is convenient to manufacture, is convenient to treat sewage and waste residues in time, and meets the effluent execution standard of Water quality Standard for farm irrigation (GB5084-2005) or pollutant discharge Standard for urban Sewage works (GB18918-2002) so as to solve the problem of rural domestic sewage.
