Description

Floating mud removing device

Technical Field

The utility model relates to an environmental remediation technical field, specificly relate to a float sludge clearing device.

Background

In the management of sewage treatment plants, the secondary sedimentation tank occupies an important position, and whether the quality of effluent water can be directly determined by effectively realizing sludge-water separation or not can be directly determined. The secondary sedimentation tank has various forms such as horizontal flow type, vertical flow type, auxiliary flow type, peripheral inflow and peripheral outflow, and the like, wherein the peripheral inflow and peripheral outflow secondary sedimentation tank is adopted by more and more sewage plants due to the advantages of good effect, stable operation and the like. However, in the actual use process, the problem of floating mud exists in the water distribution channel of the peripheral inlet and outlet secondary sedimentation tank, on one hand, the cleaning workload is increased for workers in a sewage treatment plant, on the other hand, the accumulated mud is excessive, the water distribution hydraulic condition is influenced, the mud-water separation effect of the secondary sedimentation tank is reduced, and the problem is urgently needed to be solved.

At present, the floating mud cleaning mode of a water distribution channel which goes into and goes out of a secondary sedimentation tank is manual salvage or adopts a scraper form, sludge is scraped to the tail end from the starting end, a slope is arranged at the tail end and is connected with the starting end, the sludge returns to a water inlet after being lifted by the slope, and the sludge is brought into the tank to be subjected to mud-water separation along with the stirring of water flow. However, this effect is not good for two reasons.

1. In the structural design of the peripheral inlet and outlet secondary sedimentation tank, the width of the water distribution channel is gradually reduced along with the water flow direction, namely the starting end is wider, the tail end is narrower, and the width of the scraper is less than or equal to the width of the narrowest part of the tail end, so that an area which cannot be scraped by the scraper exists inevitably, and even if the scraped floating mud flows out from the gap between the scraper and the tank wall at the tail end.

2. The floating mud is characterized by being 'floating', only a part of the floating mud scraped to the inlet is stirred by water flow to enter the secondary sedimentation tank, most of the floating mud floats again and flows to the tail end, and the reason why more and more floating mud exists in the water distribution channel is that the floating mud is not only separated from the water distribution channel, but also can be separated from the water distribution channel. The floating mud entering the pool can not settle down and still floats to the water surface, so that large-area floating mud appears in the pool.
