Problems solved by technology
At present, the national urban sewage treatment rate is only 40%. There are no sewage treatment plants in 254 cities across the country. Untreated waste water is directly discharged into nearby water bodies, causing serious pollution in coastal waters, river systems, lakes, oceans, etc., leading to eutrophication , and pollute groundwater and soil
Secondly, most urban drainage pipe networks are not well-equipped; the marketization and industrialization of urban sewage treatment are progressing slowly; therefore, research and development of treatment devices for decentralized in-situ composite reactions of domestic sewage and fecal sewage are carried out to achieve fecal sewage treatment and environmental protection. Landscaping, and making the purified water available for toilet flushing, greening, and irrigation is very necessary

The invention relates to an in-situ composite reaction treatment device for domestic sewage and fecal sewage, which is characterized in: imbedding an impermeable pool prepared by concrete and epoxy resin under the ground, top the perimeter pool connecting to a pool shed, top the pool shed being equipped with a gas outlet, inside the pool being separated by baffles into 1#, 2#, 3# aeration trough and 1#, 2#, 3# deposition trough, the deposition troughs being equipped separately with bottom sluiceway baffle, filtering net and blowoff pipe, the bottom of 1#, 2#, 3# aeration trough being equipped with aeration pipe, side of which is equipped with gas outlet hole, the top side of 1# aeration trough being equipped with a barrier basket, the disinfection discoloring trough being filled with activated char, outside the pool being equipped with a water pump, which connects to the water outlet pipe extending in a storage tank, side the water pump being equipped with a draught fan, which connects to the main air supply duct in an extensive pool, the main air supply duct being equipped with a air supply system made up of seven air supply ducts which is controlled separately by valves. The merit of the invention is characterized in that the design is reasonable, the structure is compact, the investment is small, and it is energy-saving and water-saving, and safe and convenient.
Description
technical field [0001] The invention relates to a fecal sewage treatment device, in particular to an in-situ composite reaction treatment device for domestic sewage and fecal sewage, which can realize zero discharge and consume less energy. Background technique [0002] At present, the traditional treatment method of urban domestic sewage and fecal sewage is to enter the septic tank through the sewer. The nearby water body is reused after advanced treatment. A septic tank is a concentrated structure of high-concentration organic wastewater, which can produce a large amount of hydrogen sulfide (H 2 S), ammonia (NH 3 ), methane (CH 4 ) and other harmful irritating gases, while indole, mercaptan, sulfide, skatole and other substances are produced. The odor pollution is serious, so it needs to be buried in the ground, and it needs to be cleaned and dredged regularly. In the high temperature season in summer, especially in the southern region, the heat energy generated by the...
