Background technique

With the process of urbanization, environmental pollution has become an increasingly serious problem, among which sewage treatment is the most important of many environmental problems. If the domestic sewage in the city cannot be completely purified, it will be directly discharged into the water cycle system of the earth, not only Destroying the ecological environment will also enter the human body and affect human health.

The domestic sewage of buildings in the city enters the unified downpipe through the sewer, falls from the downpipe to the underground sewage pipe, and enters the urban sewage treatment plant through the sewage pipe for purification, but the sewage in the downpipe often contains a large amount of solid waste. After entering the sewage pipe, it is easy to cause the sewage pipe to be blocked. If the filter is used for filtering, the filter screen is very easy to be blocked. It is necessary to remove the filter screen regularly for garbage cleaning, so as to prevent the garbage from clogging the filter screen, causing water accumulation in the downpipe, and causing indoor backwashing. Therefore, it is difficult to filter the sewage discharged from the downpipe in reality.

If an automatic cleaning mechanism is installed at the connection between the downpipe and the sewage pipe, power supply cables are required, the layout is difficult, and the maintenance cost is high. Therefore, it is necessary for the present invention to propose a domestic sewage treatment device that solves the above problems. The filtration of the sewage discharged from the downpipe can be realized only by external power.
