Buried municipal sewage transfer treatment system and treatment method thereof

Abstract

The invention relates to the technical field of municipal sewage treatment, and concretely relates to a buried municipal sewage transfer treatment system. The system comprises a transfer box, the left side of the transfer box is communicated with a purified water outlet pipe, the right side and the left side of the front side of the transfer box are both communicated with sewage outlet pipes, and the two sewage outlet pipes are connected to an external pump; and the right side of the transfer box is communicated with a sewage inlet box, and the top of the sewage inlet box is communicated with an external sewage pipe. Municipal sewage is treated in a grading manner, and the path of the sewage is prolonged in the transfer box, so that the sewage is effectively and sufficiently treated at each treatment point, water flows from bottom to top, impurities can be sufficiently blocked below the transfer box, and the treatment effect is improved; and a lifting system is adopted to regularly remove internal squeezed juice without manual carding, so that the sewage purification capacity is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of municipal sewage treatment, in particular to an underground municipal sewage transfer treatment system and a treatment method thereof. Background technique [0002] For a long time, the secondary biological treatment of urban domestic sewage has mostly adopted the activated sludge process, which is the most widely used secondary biological treatment process in the world, with the advantages of high treatment capacity and good effluent quality. However, there are generally high infrastructure costs, high operating costs, high energy consumption, complicated management, problems such as sludge bulking and sludge floating, and the inability to remove nitrogen, phosphorus and other inorganic nutrients. Since sewage treatment is a project that focuses on environmental and social benefits, it is often limited by funds in the process of construction and actual operation, making the problem of treatment technolog...

AI Technical Summary

Problems solved by technology

However, there are generally high infrastructure costs, high operating costs, high energy consumption, complicated management, problems such as sludge bulking and sludge floating, and the inability to remove nitrogen, phosphorus and other inorganic nutrients.

Since sewage treatment is a project that focuses on environmental and social benefits, it is often limited by funds during construction and actual operation, making the problem of treatment technology and funds the "bottleneck" of my country's water pollution control.

[0003] The situation of municipal sewage is complicated. There are many impurities, dissolved substances and other substances contained in the sewage. The traditional method of biological sedimentation treatment requires the establishment of a centralized sewage treatment station, which is expensive and requires a large amount of centralized treatment. , which makes the treatment cycle long and difficult, and the centralized treatment makes the quality of treatment greatly reduced. Therefore, a kind of sewage treatment equipment buried in the ground for regional treatment is proposed
