In addition, both the pollution load of water on the earth's surface and the burden of a sewage treatment plant are greatly reduced.
Description
Technical field
The utility model belongs to water conservancy device field, especially relates to a kind of little ecological rainwater purifying pond of regulating and storing.
Background technology
The rainwater storage pond is a kind of rainwater collection facility; Floor space is big; Generally can be built in the below of public domains such as city square, greenery patches, parking lot, main effect is to keep in the peak flow of rainfall runoff in it, treats from storage pond, rainwater to be discharged at leisure after maximum stream flow descends again.Can evade the rainwater flood peak, realize the rainwater recycle, can also play positive role the scheduling of the draining between drainage.But the granule foreign in the rainwater is easy in storage pond, deposit, and labor cleaning's difficulty is big.And, also need consider the removal problem of COD (COD), SS (suspended solid) and the nitrogen and the phosphorus of rainwater.And present most of storage pond is to adopt early-stage rainwater is simply stored or store deposition, gets into Wastewater Treatment Plant after then entering sewage network, and the removal of nitrogen phosphorus is seldom considered.In order to reduce the directly water pollution that causes of discharging of early-stage rainwater, reduce the burden of sewage network and Wastewater Treatment Plant, the purification of design collection, beautify and regulate and store and be the multi-functional rainwater storage pond particular importance of one.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, small investment, integrates purification, regulates and stores and rainwater that the dirt attitude the is beautified purifying pond of regulating and storing, and can realize the efficient removal of COD in the rainwater (COD), SS (suspended solid), nitrogen and phosphorus simultaneously.
The technical scheme of the utility model is: a kind of little ecological rainwater purifying pond of regulating and storing, comprise the pond at the bottom of, pool wall, Chi Gai, pool wall extension and first filtration beds, be fixedly connected with pool wall at the bottom of the pond; Chi Gai is fixedly connected with pool wall; The pond covers and is provided with the hole, and the pool wall top is provided with the pool wall extension, and the pool wall extension is fixedly connected with pool wall; Be provided with first filtration beds in the space that pool wall extension and pond cover upper surface form, described first filtration beds is vegetation, nutrition soil layer and sand layer from top to bottom successively.
Further, be provided with second filtration beds between the described Chi Gai and first filtration beds, described second filtration beds comprises and is laid on geotextiles that the pond covers and is laid on the solid waste materials adsorption layer on the geotextiles.Gu the waste materials adsorption layer plays filtration, coagulation, absorption, can realize the efficient removal of COD (COD), SS (suspension consubstantiality), nitrogen and phosphorus.
Wherein, described solid waste materials adsorption layer is the fine coal grieshoch.
Further; Between described first filtration beds and second filtration beds, be provided with the 3rd filtration beds; Described the 3rd filtration beds comprises water distributor, be entangled in the geotextiles on the water distributor tube wall and be positioned at the layer of gravel of water distributor upper and lower, and the water distributor tube wall is provided with the hole, and water distributor is communicated with rainwater shunting well.Water distributor is communicated with rainwater shunting well, can lay the early-stage rainwater that Storm Sewer Network is come, and filtration is preferably arranged.
Further, described pool wall extension 30-130cm above ground level.
Can reach to beautify the environment through above-mentioned each layer and purify the purpose of rainwater, simultaneously at the bottom of the pond, effective pond of forming of Chi Gai and pool wall holds and can play the effect of effectively regulating and storing.
Advantage and the good effect that the utlity model has are: simple in structure, and small investment; Collection purifies, ecology is beautified and the multi-functional one that is such as regulate and store, and can realize the efficient removal to COD, SS, TN and TP, can realize that the intensive solid of " use more on a ground " is utilized pattern, and to the metropolis of an inch of land is an inch of gold, its economy is self-evident.Can effectively reduce early-stage rainwater and directly discharge the water pollution that causes, reduce the burden of sewage network and Wastewater Treatment Plant.Be used with the original shunting well in city, pumping plant, regulating effect is remarkable, has improved the utilization rate of infrastructure.
