Automatic intercepting filtering pond, and intercepting filtering device, system and method

Abstract

The invention discloses an automatic intercepting filtering pond, which comprises a pond body (1), a retaining wall (4), an automatic switch, a particle filtering device and a drainage device (9). A water inlet (2) and a water outlet (3) are formed in the pond body (1), the retaining wall (4) is arranged in the pond body (1) and divides the pond body (1) into a water passing corridor (5) and a filtering treating area (6), and the water inlet (2) and the water outlet (3) are located in the side wall, where the water passing corridor (5) is located, of the pond body (1); the automatic switch isarranged in the water passing corridor (5) to control a water flow in the water passing corridor (5) and divides the water passing corridor (5) into a first area (51) and a second area (52), the waterinlet (2) communicates with the first area (51), the water outlet (3) communicates with the second area (52), and the automatic switch comprises a separating wall (12) and one or more automatic switch bodies controlling the communicating state of the first area (51) and the second area (52); and the particle filtering device communicates with the drainage device and is arranged in the filtering treating area (6), wherein a water feeding hole (8) is formed in the part, at the first area (51), of the retaining wall (4) and can communicate with the filtering treating area (6) and the first area(51), and the drainage device (9) can communicate with the filtering treating area (6) and the second area (52).

Description

technical field [0001] The invention relates to the diversion of municipal rainwater and sewage, in particular to an automatic interception filter tank, an interception filter device, a system and a method, and belongs to the technical field of municipal water supply and drainage. Background technique [0002] Non-point source pollution, also known as non-point source pollution, is mainly composed of soil sediment particles, nutrients such as nitrogen and phosphorus, pesticides, and various atmospheric particles, which enter water, soil, or the atmosphere through surface runoff, soil erosion, and farmland drainage. . Its randomness, universality, hysteresis, ambiguity, latentness and other characteristics increase the difficulty of corresponding research, governance and management policy formulation. After the transformation of urban rain and sewage diversion, non-point source pollution is an urgent problem to be solved. If the particulate matter and floating matter in the ...

Problems solved by technology

At present, most of the rainwater is treated by filter screen, and the rainwater is pre-treated by simple filtration. However, this method of filter screen filtration will bring many problems, such as the filter screen may be blocked, hindering the discharge of rainwater and causing urban waterlogging , the floating objects are not collected after being intercepted, so it is very inconvenient to clean up, and this method is single, it can only remove the floating objects, but cannot remove the particles in the rainwater

[0004] The Chinese invention patent application with the publication number CN107601628A discloses a deformable particle separator, an online treatment tank and an online treatment system. Sedimentation treatment is carried out, but when there is a large amount of rainfall, a large amount of rainwater must flow through the buoyancy tank, overflow tank, and overflow wall to be discharged. This series of structures hinders the water flow and affects the speed of flood discharge. Therefore, it is necessary to develop An on-line treatment pool and its control method and rainwater treatment system that can not only perform deep filtration treatment on initial rainwater, but also quickly discharge flood when the rainfall is large
