Integrated sewage treatment equipment

Integrated sewage treatment equipment

Sewage treatment integrated sewage treatment equipment is widely used, suitable for sewage treatment in small and medium-sized towns and rural areas, sewage treatment in expressway service areas, sewage treatment in tourist attractions, and in new residential quarters, sanatoriums, independent villas, airports and military units located in urban and rural areas. Camp areas and municipal sewage pipe networks cannot be connected. The sewage treatment problems in these areas need to be solved urgently, and decentralized small and medium-sized sewage treatment facilities are also the best solution. Small and medium-sized sewage processors are a reasonable supplement to large sewage treatment plants, which not only saves the cost of laying pipe networks, is economical and reasonable, but also meets the requirements of reclaimed water reuse and saves water.

1. Technical characteristics of sewage treatment equipment integrated sewage treatment equipment:

1. In terms of technology, based on the pollution characteristics of small scattered point sources and large fluctuations in water quantity and water quality, decentralized small and medium-sized sewage treatment technology should have strong shock load resistance, flexible layout, small mud production, and rapid Start-up and other requirements to meet the special requirements of the applicable environment.

2. In terms of operation management, the process operation management is simple and convenient. Due to various reasons, it is difficult to allocate professional maintenance personnel for special management in remote areas, and the problem of difficult operation, management and maintenance generally exists.

3. In economic terms, operating costs should be low. For the vast rural areas, army camps, sanatoriums and other areas, most of them are non-profit sites or economically underdeveloped areas. If the operating costs are not controlled, they will fall into the dilemma of being able to build and use them.

2. Discussion on the technology of sewage treatment integrated sewage treatment equipment

1. Constructed wetland sewage treatment technology

Constructed wetlands are artificially constructed and controlled grounds similar to swamps. Sewage and sludge are distributed on the artificially constructed wetlands in a controlled manner. In the process of flowing in a certain direction, sewage and sludge are mainly used. It is a technology for the treatment of sewage and sludge by the triple synergy of physics, chemistry and biology of soil, plants, artificial media and microorganisms.

2. Anaerobic unpowered sewage treatment technology

Anaerobic biological treatment technology is the process by which facultative anaerobic and anaerobic microbial populations convert organic matter into methane and carbon dioxide under anaerobic conditions. Anaerobic sewage treatment technology has the advantages of low cost, low operation cost, and energy recovery and utilization. It has been more and more widely researched and applied in the treatment of dispersed domestic sewage. In recent years, more and more efficient anaerobic treatment equipment and technologies have been developed, such as Upflow Sludge Bed Reactor (UASB), Anaerobic Filter (AF), Anaerobic Expanded Granular Sludge Bed (EGSB), etc. . According to the characteristics of scattered point source sewage, the anaerobic unpowered sewage treatment device adopts the process of primary sedimentation tank + anaerobic sludge bed contact tank + anaerobic biological filter tank, and the whole set of devices is buried underground. The process is simple and does not require special management. Does not consume energy. Engineering practice, the investment of this sewage treatment device is about 2000 yuan/m3, the treatment effect is good, CODCr: 50%-70%, BOD5: 50%-70%, Nspan-N: 10%-20%, phosphate: 20% -25%, SS: 60%-70%, the treated sewage reaches the secondary discharge standard.
