Description

TECHNICAL FIELD

[0001] The utility model belongs to sewage treatment technical field, more particularly to a sewage treatment and purification tank equipment. BACKGROUND

[0002] Rural sewage treatment is a systematic project, and is also an important content of rural human settlement environment improvement action. It is a new idea to realize rural water environment improvement and quality promotion to construct green treatment facilities according to local conditions, advocate ecological treatment mode and take green development road.

[0003] Foreign developed countries have carried out research and application of rural water pollution treatment technology and management early, have rich experience, and have formed relatively mature treatment technology and application mode with different characteristics. For example

[0004] Japan has created decentralized sewage treatment technology with "purification tank" as key facility in the field of rural sewage treatment, and has established a complete rural sewage treatment management system. The Japanese purification tank evolved from a simple septic tank, which was originally used to treat fecal sewage. With continuous development, a combined type of enhanced purification tank has been formed, which can realize simultaneous enhanced removal of organic matter, nitrogen and phosphorus, and has formed a mature rural domestic sewage equipment integrating sewage collection and treatment. In recent years, integrated purification tank technology has been introduced for rural sewage treatment in China and improved according to actual requirements. However, the actual investigation found that the decentralized purification tank did not work well in application, which has a great relationship with the differences in rural sewage characteristics, discharge standards, supporting infrastructure and other conditions in China.

[0005] In the United States, Canada and European developed countries, due to the high overall economic development level of the society, the rural area is wide and sparsely populated, and the rural domestic sewage treatment mainly uses decentralized biological membrane system or artificial ecological system, which has the characteristics of good pollutant removal effect and good effluent quality, but the cost is high and the operation and maintenance are complex. In developed areas such as Shanghai and Jiangsu in China, biological membrane and membrane bioreactor have been partially applied, but they are not suitable for popularization and application in rural areas with low economic development level.

[0006] Australia adopts a sewage treatment technology named "Filter". The system uses nanometer pipe sewage for irrigation of grass and crops, and the organic matter in the sewage is filtered and decomposed by microorganisms for absorption, and then collected and discharged by laying pipe network. This kind of technology mode is more suitable for Australia with wide land area. Although this mode cannot be directly used for rural sewage treatment in China, the mode of combining rural sewage treatment with local ecological system for collaborative treatment and resource utilization has great reference significance.

[0007] The rural population in China is relatively dispersed and not concentrated, and is limited by natural conditions and terrain, so that domestic sewage is extremely difficult to collect, most of the domestic sewage in rural areas is discharged after simple treatment by a septic tank, which not only poses a potential threat to a drinking water source, but also is extremely easy to pollute the environment, or a separate drainage pipeline is installed, but this method has a large difficulty in laying a pipe network and a high cost, and does not meet the needs of economic development and practicality, and therefore, based on the above defects, the applicant proposes a more optimal technical solution to solve the above technical problems.

[0008] The information disclosed in this part of the background is only intended to increase the understanding of the overall background of the present application, and should not be regarded as acknowledging or implying in any form that the information constitutes prior art known to those skilled in the art.
