Description

A kind of low water damage dmp filter pond
Technical field
The present invention relates to a kind of rainwater purification equipment, and in particular to a kind of low water damage dmp filter pond.
Background technology
With the quickening of urbanization process, Permeable stratum area dramatically increases on ground, pollutant at these fluid-tightly Built up on face, when rainfall, pollutant is poured rainfall runoff system and forms rainwater runoff pollution by rain drop erosion ground.Rain Water runoff pollution is a kind of diffusion contact scar, and pollutant enters natural water, causes water pollution, the pollutant is with particle Thing, suspension, floating object form are present, containing poisonous and harmful substances such as organic matter, heavy metals.Therefore, urbanization process and industry Changing development causes water source judgment and rain flood to endanger getting worse.
With water source judgment and the aggravation of rain flood harm, rainwater is subject to Collection utilization and carries out the comprehensive regulation as water resource Turn into important emerging problem.In overall city planning, most of combined drainage system that the past uses is changed a social system, It is changed to separate system or the drainage system processed that dams.Serious with urban atmospheric pollution and ground pollution, rainwater runoff pollution is further Seriously, especially the more early-stage rainwater of pollutant, the pollutant index peak of the early-stage rainwater of certain areas are much high In typical urban sanitary sewage.Therefore, it is necessary to rainwater, especially early-stage rainwater are handled.
Collection processing of the China to early-stage rainwater at present is scarcely out of swaddling-clothes, and collects early-stage rainwater and does not allow only it to arrange Enter water pollution water quality, and the filtration, purification processing for early-stage rainwater then seldom considers, it is dirty that majority is directly discharged into municipal administration life Grid.The pollutant concentration contained in early-stage rainwater is higher, especially road early-stage rainwater, is directly discharged into sanitary sewage pipe network Larger load can be brought to sewage plant.
The content of the invention
To solve the above problems, the present invention provides a kind of low water damage dmp filter pond, the filtering ponds include well body, are located at Cover plate above well body, positioned at the water inlet pipe and outlet pipe of well body opposing sidewalls;Longitudinally disposed barricade inside well body;In barricade The supporting plate set between the side wall where outlet pipe, the barricade and supporting plate will be divided into inside well body:Where water inlet pipe Side wall and barricade between pre- decanting zone;Between side wall where barricade and outlet pipe, the filtering area above supporting plate With the decanting zone of lower section;
The pre- decanting zone connects with water inlet pipe;The filtering area connects with outlet pipe;
The barricade is provided with water-carrying groove from well body bottom surface, and upper end is provided with overflow launder from cover plate;
