Problems solved by technology

However, the pre-treatment of this invention is only to filter and remove impurities, and the microbial anaerobic reaction requires strict pH requirements and temperature requirements, otherwise the treatment function of the anaerobic tank is not good, and it is easy to cause odor

Embodiment 1

[0025] as attached figure 1 As shown, a biological rope purification system is sequentially connected with a regulating tank, a metering tank, an anoxic tank, an anaerobic tank, an aeration tank and a sedimentation tank. Sewage enters from the regulating tank, neutralizes the acid and alkali in the regulating tank, adjusts the pH to 6.5-7.5, and through its own sedimentation, the preliminarily separated solid impurities are precipitated and separated through the sewage outlet, and then the sewage enters the metering tank through the flow control valve to adjust For the amount of water entering the subsequent microbial reaction, use a dissolved oxygen meter to test the dissolved oxygen in the tank, control the dissolved oxygen in the anoxic tank to 0.2-0.5mg / L, and control the dissolved oxygen in the anaerobic tank to less than 0.2mg / L , the dissolved oxygen in the aeration tank is controlled at 1-4mg / L through the aeration equipment, and the temperature in the anaerobic tank i...

Abstract

The invention belongs to the field of sewage purification, and relates to household sewage treatment, in particular to a biological rope purifying system. The biological rope purifying system comprises a regulation pond, a measurement tank, an oxygen deficit tank, an anaerobic tank, an aeration pond and a precipitation tank, which are sequentially connected, wherein a flow control valve is arranged between the regulation pond and the measurement tank; a methane collecting pipeline is arranged between the top of the anaerobic tank, a temperature controller and a detection opening are arranged on the anaerobic tank, and the temperature of the anaerobic tank is controlled to be 30-40 DEG C; the anaerobic tank and the oxygen deficit tank are respectively communicated with the aeration pond through a stripped sludge recovering pipeline; the precipitation tank is communicated with the aeration pond through a sludge precipitating pipeline; and aeration equipment is arranged in the aeration pond. The biological rope purifying system disclosed by the invention has the advantages of being good in purifying effects and high in microorganism utilization degree, and besides, the situation thata degradation tank smells stinky can be avoided.

Description

technical field [0001] The invention belongs to the field of sewage purification, relates to domestic sewage treatment, in particular to a biological rope purification system. Background technique [0002] In recent years, with the rapid development of industry and agriculture and the improvement of people's living standards, a large amount of industrial wastewater, agricultural wastewater and domestic sewage flow into oceans, lakes and rivers, causing serious water pollution, and the problem of eutrophication of water bodies is also becoming more and more serious. Studies have shown that most of the pollutants in water are mainly organic pollutants, and the best treatment method is biological treatment, because compared with chemical and physical and chemical treatment, biological treatment has better treatment effect and lower investment and operation costs. At present, most sewage treatment reaction devices often adopt a single anaerobic or aerobic form, which cannot adap...
