[0059] The integrated site wastewater treatment system of the present application has at least the following advantages:

[0060] (1) The wastewater is introduced into the tank body through the water inlet pipe. At this time, the lifting member and the baffle are engaged, that is, the wastewater enters the first accommodating chamber of the tank body. Since a filter is provided between the tank body and the lifting member, the wastewater is filtered out of larger particles, such as gravel, through the filter, and preliminary filtration of larger impurities can be performed.

[0061] (2) After the initial filtration, the lifting member and the baffle are kept in the engaged state, and the wastewater is still in the first receiving chamber. After the wastewater is allowed to settle, the lifting member and the baffle are separated, and the upper clear liquid flows into the second receiving chamber from the separation area between the lifting member and the baffle, and the lower sedimentation liquid flows out from the first outlet pipe. When the upper clear liquid completely enters the second receiving chamber, the lifting member and the baffle are engaged, and the reaction liquid is introduced into the second receiving chamber from the liquid inlet pipe to further settle the internal wastewater. Further wastewater treatment can be achieved by adding the reaction liquid to increase the wastewater settling effect and further increase the amount of recovered liquid.

[0062] (3) During the reaction process, the stirring action of the stirring paddle and the blowing action of the backflush pipe enable the internal wastewater and the reaction liquid to be fully mixed, thereby further ensuring the mixing effect, thereby increasing the wastewater sedimentation effect and further increasing the amount of recovered liquid.

[0063] (4) The present application provides multiple backflush pipes, which are evenly arranged at the bottom of the tank to increase the uniformity of gas introduction.

[0064] (5) The filter screen of the present application is provided with multiple layers, which are arranged at intervals along the axial direction of the tank body to increase the filtering effect.
