Example 2

In order to improve the practicability, the embodiment is further improved on the basis of the embodiment 1, and the improvement is that: an overflow grit chamber 10 is arranged on one side of the grit chamber 2, the grit chamber 20 and the pre-filtering chamber 19, an overflow water inlet 9 is formed between the overflow grit chamber 10 and the grit chamber 2, the overflow water inlet 9 is higher than the filtering water inlet 3, an overflow grit chamber water passing hole is formed between the overflow grit chamber 10 and the pre-filtering chamber 19, and the overflow grit chamber water passing hole 13 is lower than the filler filtering layer 7.

Specifically, an oil separation plate 21 and a water flow plate 18 for reducing the water flow rate are arranged in the overflow grit chamber 10.

The utility model discloses a theory of operation is:

water enters a grit chamber 2 from a water inlet 1, sand and stones in the water passing through the grit chamber 2 naturally sink and fall into the bottom of the grit chamber 2, the water after grit settling enters a filter grid 4 through a filter water inlet 3, the filter grid 4 can isolate suspended matters in the water, small-particle sand and mud in the water settle again in the filter grid 4 and fall into a basket grid 5 after settling, the suspended matters of impurities isolated by the filter grid can fall into the basket grid along the inclination of the grid, the water passes through the upper water of the filter grid 4 and enters an oil-separation filler filtering layer 6, oily oil stains in the water are isolated due to the fact that the water density floats on the water surface, and the water finally flows to a water outlet 8 through the oil-separation filler filtering layer 6, the water which enters the lower water settling chamber 20 after being filtered by the filter grating 4 flows into the pre-filtering chamber 19 through the water hole 17, is filtered by the filler filtering layer 7 and then flows to the municipal pipe network or the downstream river through the water outlet 8.

When the water amount of the inlet 1 is increased to exceed the filtering amount of the filtering grid 4, the water level of the grit chamber 2 rises to exceed the overflow water inlet 9 and then enters the overflow grit chamber 10 from the overflow water inlet 9, the overflow grit chamber 10 is provided with an oil separation plate 21, oil floats on the oil separation plate on the water surface to separate the oil in the overflow grit chamber 10, a water flow plate 18 is arranged in the overflow grit chamber 10, the water flow plate 18 changes the water flow direction to be S-shaped and slows down the water flow speed to enable the silt in the water to be more effectively settled in the overflow grit chamber, water holes 13 of the overflow grit chamber are arranged between the overflow grit chamber 10 and the pre-filtering chamber 19, and the water after the silt is settled by the water flow plate 18 enters the pre-filtering chamber 19 from the water holes 13 of the overflow grit chamber and then enters the upper filler filtering layer 7 of the pre-filtering chamber to be filtered and then flows to a municipal pipe network or a downstream.

This patent product is equipped with access cover and access ladder and filters the basket, filters and to carry the blue half year time and need clear up once, opens access cover and will filter through the access ladder and carry the blue clean up and put back again, if do not have the clearance grid for a long time, the grid filter capacity reduces, and the rising water of grit chamber water level gets into overflow grit chamber, and overflow grit chamber water level rises through overflow play water flow direction through delivery port flow direction municipal pipe network or low reaches river
