A kind of owt sewage treatment system

Abstract

The invention provides an OWT sewage processing system. The system comprises a buffer well with a water inlet pipe (A) and a water outlet pipe (A); a separation hydrolysis tank with a water inlet pipe(B) and a water outlet pipe (B); a water diversion tank with a water inlet pipe (C) and a water outlet pipe (C); a standard osmotic chamber with a water inlet pipe (D); and a water storage tank witha water inlet pipe (E). A biological pad, a seepage area, and a saturation area with a water outlet pipe (D) are arranged under the standard osmotic chamber in sequence. The buffer well is sequentially communicated with the separation hydrolysis tank, the water diversion tank, the standard osmotic chamber, and the water storage tank. The buffer well, the separation hydrolysis tank, the water diversion tank, the standard osmotic chamber, and the water storage tank are all arranged under a frozen soil layer. The opening of the water inlet pipe (A) is not higher than a sewage pipeline. All devices are arranged under the frozen soil layer, and thus thermal insulation facilities are not needed in winter. Sewage can go through each processing apparatus under the effect of self gravity, so the system does not need extra power, and a large amount of energy is saved. Moreover, the system does not need management. At the same time, sewage is subjected to an anaerobic treatment, an aerobic treatment, a physical and chemical treatment, a sterilization treatment, a phosphor removing treatment, and a de-nitrification treatment, and the sewage is converted into clean water.

Description

technical field [0001] The invention relates to the field of water treatment systems, in particular to an OWT sewage treatment system. Background technique [0002] In the past ten years, all kinds of rural domestic sewage treatment technologies in my country have not considered the comprehensive indicators and standards of national sewage treatment and the basic requirements of farmers, resulting in hundreds of billions of equipment thrown in rural areas, which cannot be used or cannot meet the standards. Therefore, in the existing market, some enterprises have also made corresponding designs for these problems. [0003] For example, the Chinese patent "Domestic Sewage Treatment System" with application number 201210295563.9 discloses a domestic sewage treatment system, including a regulating tank, an anoxic tank, a contact oxidation tank, a sedimentation tank, a disinfection tank, a sludge tank, a lift pump and a rotary Type fan, regulating tank, anoxic tank, contact oxid...
