Sewage treatment system

Abstract

The invention discloses a sewage treatment system, which is characterized by comprising a sewage collection tank, a coarse gravel filtration tank, a fine sand filtration tank, a sediment purificationpool, an ecological ditch and an ecological pond, wherein a water inlet of the sewage collection tank is communicated with a sewage drainage pipe, and a water outlet of the sewage collection tank is communicated with the coarse gravel filtration tank; sewage to be treated firstly enters the coarse gravel filtration tank through the sewage collection tank so as to be subjected to preliminary ecological filtration, is then subjected to secondary ecological filtration by means of the fine sand filtration tank, and is finally purified by means of sedimentation of the sediment purification pool; when the water amount in the sediment purification pool exceeds a preset standard amount, the water subjected to sediment purification enters the ecological ditch so as to be subjected to deep purification, and finally flows into the ecological pond. The sewage treatment system adopts three stages of purification, i.e., the coarse gravel filtration tank, the fine sand filtration tank and the sediment purification pool, and then further adopts the ecological ditch and the ecological pond for performing deep purification, thus not only improving the water quality purification effect, but also having a certain water accumulation effect; the system maintains the balance of aquatic ecological environment by combining the concept of a sponge city.

Description

technical field [0001] The invention relates to the technical field of sewage control and treatment, in particular to a sewage treatment system. Background technique [0002] With the rise of farmhouse tourism, rural farmer families across the country have gradually produced more domestic sewage due to the influx of tourists. The concentrated pollution sources have overloaded the local rural ecological environment capacity, while the original Some technical methods and technical equipment are too large, suitable for the planning and construction of the entire village, and the later maintenance costs are too high, so that many equipment have not been used for a long time, and the technology used is also a physical and chemical method, which leads to Poor water quality occurs frequently in most beautiful villages.

Problems solved by technology

[0002] With the rise of farmhouse tourism, rural farmer families across the country have gradually produced more domestic sewage due to the influx of tourists. The concentrated pollution sources have overloaded the local rural ecological environment capacity, while the original Some technical methods and technical equipment are too large, suitable for the planning and construction of the entire village, and the later maintenance costs are too high, so that many equipment have not been used for a long time, and the technology used is also a physical and chemical method, which leads to Poor water quality occurs frequently in most beautiful villages

[0003] In addition, the flow control of the rural decentralized sewage treatment facilities in the early stage and the effluent quality of the tail water in the later stage have not been fully considered and monitored.

Therefore, it is easy to cause damage to the system equipment, poor water quality of the system, etc.
