Description

Sewage interception overflow device of drainage pipeline

Technical Field

The utility model relates to the technical field of sewage treatment equipment, in particular to a sewage interception overflow device of a drainage pipeline.

Background

In urban drainage systems, initial stormwater is a focus of attention for stormwater pollution. The initial rainwater refers to the rainwater at the initial stage of rainfall, and generally refers to the rainfall on the ground with the thickness of 10-15mm, so as to form surface runoff. As the rain water dissolves a large amount of acidic gases, automobile exhaust, factory exhaust and other pollutant gases in the air at the early stage of rainfall, and after falling on the ground, the rain water also contains a large amount of pollutants due to flushing of roofs, asphalt concrete roads and the like, and the pollution degree of the rain water at the early stage is higher and even exceeds that of common urban sewage. The initial rainwater is often directly discharged into the urban drainage system through the inlet for rain, which brings a certain degree of pollution to the urban drainage system.

Through searching, chinese patent document CN211621901U discloses a sewage interception device for urban road surface sewage. When the leaves on the surface of the pavement drainage grating are blocked, accumulated water around the pavement drainage grating can be gradually increased, the cavity floater automatically floats along with the increase of the accumulated water, and the standby drainage groove is opened for rapid drainage; the blocked leaves can fall into the sedimentation dirt-intercepting pond along with water flow from the standby water drainage groove, and are retained under the action of the blocking net frame, and finally enter the sewage treatment center through the sewage drainage pipeline.

According to the sewage interception device, the sewage interception device is used for treating the situation that the road surface drainage grating is blocked, and the structure of the drainage grating can be timely adjusted, so that accumulated water is timely discharged due to blocking around the drainage grating. The sewage interception device can only filter out the larger impurities such as leaves, broken stones and the like in the initial rainwater, avoid the larger impurities to directly enter the urban drainage system through the inlet for stom water, and still lack the treatment of the pollutants dissolved in the initial rainwater.

For another example, chinese patent document CN103334486a discloses an automatic overflow sewage interception device for a gully. The overflow dirt-intercepting device comprises a clamping seat, wherein the clamping seat comprises a grease absorbing rope clamping groove. The overflow sewage interception device intercepts pollutants entering the rainwater inlet through the sewage interception filter screen, prevents the rainwater inlet and a rainwater pipeline from being blocked, and improves the drainage capacity of the rainwater pipe network; the arrangement of the grease absorbing rope can effectively control grease pollutants in runoff rainwater, reduce the treatment cost of a subsequent sewage treatment plant and lighten urban water pollution.

However, in the actual use process of the overflow dirt intercepting device, due to the assembly structure of the overflow dirt intercepting device and the inlet for stom water, the filter screen is easy to be blocked by impurities, initial rainwater is difficult to enter the inlet for stom water, and then the rainwater is accumulated on the ground surface, so that the urban drainage system cannot normally run.

In summary, how to design a sewage interception device for filtering the initial rainwater entering the gully in the initial rainwater treatment process, so as to improve the treatment effect on the initial rainwater, is a technical problem to be solved by those skilled in the art.
