Problems solved by technology

Due to China's vast territory, some people's living areas are concentrated and some are scattered. Centralized sewage treatment will face many difficulties. Once the sewage is directly discharged into the water system, it will seriously pollute and destroy the ecological environment.

Abstract

The invention relates to a life miscellaneous wastewater biochemical treatment device and is characterized in that the life miscellaneous wastewater biochemical treatment device comprises a septic tank, a high water tank, a straight-tube sedimentation chamber and a micro-aeration biological filter tank which are connected in sequence; the septic tank and the high water tank are connected by a water pump; the high water tank is disposed higher than the septic tank, the straight-tube sedimentation chamber and the micro-aeration biological filter tank; a thick grid and a fine grid are disposed inside an input pipe of the septic tank, which is equipped with a sedimentation chamber, an oil and foam separation tank and two filter tanks; the straight-tube sedimentation chamber comprises a sedimentation chamber housing and a straight-tube filter core; the micro-aeration biological filter tank comprises a biological filter tank housing, at least two biomass tanks are equipped inside the biological filter tank housing, and a micro-aeration head is arranged on the lower portion of each biomass tank. The invention has a simple and compact structure and requires low manufacturing cost. According to the invention, biomass balls are used as the carriers of biological bacteria and the biochemical treatment method is adopted to process organic wastewater, thus reducing the processing cost, raising the processing effect and minimizing the pollution of the life miscellaneous wastewater to the environment as well as the destruction of the life miscellaneous wastewater to the ecological environment.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a biochemical treatment device for domestic waste water. Background technique [0002] Schools, hotels, cooking, catering, bathing pools and other places produce a large amount of sewage every day. The pollution sources in sewage are mainly organic matter and chemical detergents, such as feces, washing water, bath water and other miscellaneous drainage. The ammonia nitrogen and phosphorus content in these miscellaneous drainage Very high. Due to China's vast territory, some people's living areas are concentrated and some are scattered. Centralized sewage treatment will face many difficulties. Once the sewage is directly discharged into the water system, it will seriously pollute and destroy the ecological environment. According to a study by the National Academy of Environmental Sciences, one gram of oil can pollute 15m 2 On the water surface, 0.5 kg of oil needs to be diluted with ...
