Intercepting filter on-line treatment pool and control method thereof, and rainwater treatment system

Abstract

The invention discloses an intercepting filter on-line treatment pool and a control method thereof, and a rainwater treatment system. The intercepting filter on-line treatment pool comprises a pool body as well as a water inlet and a water outlet which are formed in the pool body, and also comprises a blocking wall arranged in the pool body; the blocking wall partitions the pool body into a waterpassing gallery and a filter treatment area; a particle filtering device and a water discharging device are arranged in the filter treatment area; a water inlet hole is formed in the part, which is positioned on a first area, of the blocking wall; the water inlet hole is used for communicating the filter treatment area and the first area; and the water discharging device is used for communicatingthe filter treatment area and a second area. The intercepting filter on-line treatment pool is simple in structure and convenient to operate; and the on-line treatment pool can deeply filter rainwaterat the early stage of rainfall, can draw off floodwater rapidly when the flow quantity is high, can reduce pollution to a natural water body and can guarantee the rainwater treatment effect of the rainwater treatment system.

Description

technical field [0001] The invention relates to rainwater pretreatment, in particular to an on-line treatment pool for interception and filtration, a control method thereof, and a rainwater treatment system. 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 rainwater are not intercepted and disposed of directly into the natural wa...

AI Technical Summary

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
