Description

TECHNICAL FIELD

[0002] Water conservancy and hydropower projects bring great convenience to economic and social development and people's production and life in terms of flood control, power generation, navigation and cross-regional water transfer. On the other hand, water conservancy and hydropower projects need to be built in certain water areas. Under such conditions, the discharge of construction wastewater will inevitably have temporary or even permanent significant impact on the local environment and long-term economic and social development. The solid sediments contained in the wastewater fall to the bottom of the water and cover the spawning grounds of fish and shrimp, disrupting the ecological balance, affecting the normal growth of aquatic organisms and destroying human water sources. Therefore, the construction wastewater of water conservancy and hydropower projects needs to be treated by multiple stages before being discharged. During the sewage treatment process, the construction waste in the sewage needs to be filtered and cleaned. The traditional grid filtering and cleaning can only filter relatively large waste, and the cleaning is not complete. During the filtering process, the filtered waste needs to be manually cleaned frequently, which is time-consuming and labor-intensive. Part of the small debris needs to be settled for a long time before the waste can be removed, and the cleaning speed and efficiency are poor. SUMMARY

The push plate (3014) is lifted and pressurized to push the sewage to flow. The sewage is pressurized and pushed by the primary filter ring (4032) through the primary filter. Large pieces of engineering debris are filtered. The sewage after the first filtration continues to flow and passes through the fine filter ring (4034) for secondary filtration. The filtered sewage continues to flow and is discharged through the filtered water discharge pipe (404) for sewage purification of other projects. The sewage is squeezed and discharged. After discharge, the push plate (3014) is controlled to slide down and control the sewage to be refilled. The filtration is repeated many times. S4.
