[0002] Sewage treatment: The process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. However, when the sewage is dumped into the interior of the box, the sewage contains a certain degree of larger particles, which will affect the mixing of the sewage and the medicine, and is not conducive to the subsequent discharge of the mixture. In addition, the medicine and sewage are mixed and discharged directly, so that the sewage contains trace impurities, which affects the purification of the sewage and thus affects the environmental protection work.

After the filter plate provided in this scheme is placed on the upper surface of the supporting plate, the sewage can enter the diversion box through the water inlet pipe, and then flow evenly to the inside of the mixing box, so that the filter plate can filter the larger particles contained in the sewage. After the medicine in the mixing box is mixed with the sewage, it can flow to the inside of the sedimentation box through the connecting pipe, and can be statically precipitated for a period of time in the sedimentation box, so that the fine debris in the mixture is static at the bottom of the sedimentation box, thereby further improving the sewage purification work.
