Problems solved by technology

Although soil treatment can meet the technical requirements of the current "Pollutant Discharge Standards for Urban Sewage Treatment Plants" GB18918-2002, it requires a long residence time in water bodies and covers a large area. Since sewage mainly needs to be treated by soil infiltration, soil treatment The technology is greatly affected by the climate. During the rainy season, the soil absorbs a large amount of rainwater and is saturated. In winter, the soil surface freezes, affecting water infiltration and isolating the air. The activity of microorganisms in the soil will also decrease at low temperatures, which also leads to a reduction in sewage. Treatment efficiency, but the amount of sewage to be treated is not changed by climate change, which brings great inconvenience to the management of sewage treatment and discharge

Abstract

The invention discloses a micro-power sewage biological rapid filtration system. The micro-power sewage biological rapid filtration system comprises a pretreatment tank, a program-controlled rapid filtration field and a disinfection reaction tank, and the pretreatment tank, the program-controlled rapid filtration field and the disinfection reaction tank are orderly connected. The program-controlled rapid filtration field comprises a first rapid filtration field main-body, a second rapid filtration field main-body, a water-inlet air-inlet mechanism arranged in the middle of each one of the rapid filtration field main-bodies and backflow mechanisms respectively arranged at two sides of each one of the rapid filtration field main-bodies. Communicated perforated overflow pipes are arranged between upper parts of the water-inlet air-inlet mechanisms and upper parts of the backflow mechanisms. The rapid filtration field main-bodies are filled with multiple functional filter material layers. The inner walls of the rapid filtration field main-bodies are coated with impermeable PE films. In aeration, through use of gas stripping effects produced in water inflation, water in the water-inlet air-inlet mechanisms automatically overflows and flows into the backflow mechanisms so that additional electricity consumption equipment for driving water circulation is avoided and an energy consumption cost of the system in use is further reduced.

Description

technical field [0001] The invention relates to a domestic sewage treatment system, in particular to a low-energy microdynamic sewage biological rapid filtration system and a process, which belong to the technical field of environmental protection and sewage treatment engineering. Background technique [0002] With the construction of "new countryside" and the rapid development of villas and recreational areas, a new type of decentralized small domestic sewage treatment facility has become the new favorite of the environmental protection market. Currently commonly used sewage treatment processes, such as biological filter, contact oxidation, SBR, and soil treatment, cannot well meet the special requirements of high standards, low energy consumption, low investment, free management, and less land occupation in this field for sewage treatment facilities. . [0003] Due to the short passing time of biological filter technology, the complete nitrification of ammonia nitrogen an...
