Problems solved by technology

However, this type of technology only realizes the function of a circulating pool for sedimentation of pollutants, and cannot remove the phosphorus contained in rainwater.
[0006] Also, Republic of Korea Patent No. 10-0901263 discloses a technology for removing phosphorus in rainwater, but the problem is that floating matter and sludge cause clogging and quickly lose the filtering function
[0007] Republic of Korea Patent Publication No. 10-2014-0145305 uses filter material to remove phosphorus from rainwater, and adopts various measures to prevent clogging, but its structure prevents sludge and floating matter from completely settling and causing them to flow into the filter layer, resulting in clogging Possibility increases, backwash uses some power, but it is difficult to have a specific effect on initial rain

Abstract

The invention belongs to the technical field of rainwater treatment devices, and relates to a device, which is used for settling a pollutant in rainwater entering a rainwater pipe and filtering and discharging the rainwater. A removing and reducing device for a non-point pollution source comprises a sand settling pond, a settling pond, a flow adjusting pond, a filtering pond and a treated water pond, wherein one side of the sand settling pond is connected with a water inlet pipe; the upper end of a side wall on the other side of the sand settling pond is communicated with the settling pond; moreover, multiple filtering membranes are arranged at the interior of the sand settling pond; the interior of the settling pond is provided with a bottom opening or a partition wall which has a certain distance to a bottom surface; multiple absorbent paper fixing accessories are formed on the partition wall or two side walls in a protrusion manner; the upper end of one side wall of the flow adjusting pond is communicated with the settling pond; the other side of the flow adjusting pond is connected with the bottom of the filtering pond; the filtering pond is provided with more than two filtering layers, and is communicated with a filtered water discharge pipe of the treated water pond; the treated water pond is used for storing filtered water passing through the filtering pond. By using the removing and reducing device for the non-point pollution source, which is provided by the invention, the blockage possibility is not only structurally reduced obviously, the backwash and the reverse transfer process of backwash water are automatically completed through the backwash water and compressed air, the removing and reducing device for the non-point pollution source but also can be used for a long time without carrying out maintenance.

Description

technical field [0001] The invention belongs to the technical field of rainwater treatment devices, and relates to a device for precipitating pollutants in rainwater entering a rainwater pipe, filtering and discharging the rainwater. Background technique [0002] Pollutants that flow out through surface water in rainy days are called non-point source pollutants. Traffic pollutants next to roads, dust and garbage in urban areas, and other air pollutants accumulated on the ground are washed into stormwater pipes by rainwater and discharged into rivers. In this case, rainwater is the main non-point pollution source. [0003] The results of domestic river pollution load surveys carried out after 2000 show that the proportion of non-point pollution sources in the total discharge load (BOD benchmark) is about 50%. In order to purify the water quality of rivers, it is necessary to strengthen the management and supervision of non-point pollution sources has become a consensus. [...
