Description

The Heavy Rainfall Process early-stage rainwater stream abandoning is without taking up an area on the spot treating apparatus and processing method thereof
Technical field
The present invention relates to a kind of devices and methods therefor of technical field of waste water processing, specifically a kind of Heavy Rainfall Process early-stage rainwater stream abandoning is processed and processing method on the spot without taking up an area.
Background technology
The at present a lot of cities of China are owing to the combined system reason, so that rainwater has entered sewage treatment pipeline, this subject matter wherein bringing is that the quantity of sand and mud in the sewage is very high, have a strong impact on the final processing of sewage plant sludge, and had serious abrasive action for plant equipment of aqueduct and mud etc.Simultaneously, propelling along with China's energy-saving and emission-reduction, requirement is carried out middle water reuse for what rainwater was tried one's best, and early-stage rainwater is owing to carried a large amount of silt and pollutant, process if mix with the later stage rainwater, then can have a strong impact on water reuse purpose in the rainwater wherein, and increase rainwater processing load.Therefore, be necessary very much early-stage rainwater shunted and throw aside, or process separately.
The Permeable stratum area in city, the increase such as roof, street, parking lot etc. makes suitable watershed be covered by fluid-tight hardened surface, therefore causes rain (snow) water directly to permeate the ground, and has increased the flow of rainwash.Simultaneously, urbanization has caused the decline of rainfall runoff water quality on the impact of Urban Hydrologic environment, its reason is that mainly urbanization is based on the purpose that rainfall runoff is drained as early as possible to the transformation of drainage system, the increase of rainfall runoff flow velocity and flow, so that runoff significantly increases the souring on roof, road surface, the polluter of city underlying surface deposition is dissolved by rainwater or carries the diffusion that pollutes; Because China's overwhelming majority sewerage system adopts combined system, rainfall runoff enters sewage network, has increased the load for the treatment of facility.If can realize the utilization of rainwater, the processing load of municipal sewage will be solved effectively.And wherein the most key be the efficient processing target of realizing municipal sewage initial Split-flow water, thereby can directly use after making the later stage rainwater-collecting, so then can effectively reduce the treating capacity of rainwater.
The use of rainwater also can be used as other water such as air conditioning cooling water, fire demand water, car washing water, flowers and plants pouring, landscape water, road cleaning etc. except can be used as lavatory, street wash water, purposes is wider.The research of China's Application of Urban Rain Water and application start from the eighties in 20th century, are developed the nineties." building and residential quarter rainwater utilization engineering legislation " implemented on April 1st, 2007 plays positive impetus to Application of Urban Rain Water.The processing procedure of rainwater is similar to general water treatment procedure at present, mainly adopts physico-chemical process.
Find through the literature search to prior art, (day for announcing: patent specification 2008.07.16) has disclosed following content: a kind of middle water reuse and rainwater sewage separation centralized processor are provided for CN101220603 for Chinese patent Granted publication number, comprise the coarse filtration sedimentation basin, the biochemical treatment tank that contains the sewage decomposing pool, the Buffer Pool that is communicated with coarse filtration sedimentation basin and biochemical treatment tank respectively and the fine filtering pond that contains movable filter bed that is communicated with Buffer Pool, middle water handling reclamation control room, middle water water storage pond, middle water handling reclamation has central operator in the control room, the ultra-filtration and separation machine that is communicated with the fine filtering pond of acceptor center control panel control, concentrated sewage well by pipeline respectively with biochemical treatment tank, the coarse filtration sedimentation basin, Buffer Pool, the fine filtering pond is communicated with.Both solve the shunting of sewage rainwater and focused on problem, obtained again recycled water.This patent technological process is longer, and needs the long time of staying.The technical problem to be solved in the present invention is: Heavy Rainfall Process early-stage rainwater stream abandoning sewage, its silt content is higher, and contains the complicated pollutant of Chuck Steak, water reuse standard in satisfying after this technique is disposed.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of Heavy Rainfall Process early-stage rainwater stream abandoning to process on the spot and processing method without taking up an area.The initial Split-flow rainwater is through entering the setting pot precipitation behind the flow abandoning apparatus, after enter the water intake mechanism water distribution, carry out the soil processing from flowing into the sewage purification soil ditch, pass through special construction, solve the soil method blockage problem of disposing of sewage, can make the initial stage throw aside rainwater and reach first discharge standard (GB18918-2002) in " urban wastewater treatment firm pollutant emission standard ", and can prevent effectively that the problem of stopping up occurs locking system.
The present invention realizes by following technical scheme:
The Heavy Rainfall Process early-stage rainwater stream abandoning that the present invention relates to is processed without taking up an area on the spot, comprise: water intake mechanism, overburden layer, mixed layer, soil horizon, gravel layer, fine sand layer, basal layer and drainage mechanism, wherein: overburden layer, mixed layer, soil horizon, gravel layer, fine sand layer and basal layer from top to bottom set gradually, water intake mechanism is connected with mixed layer, and drainage mechanism is connected with gravel layer and fine sand layer.
Described water intake mechanism comprises: intake pool, several distribution channels, wherein: the intake pool outlet is connected with distribution channel, distribution channel is arranged in the mixed layer, rely on flow by gravity to enter in the groove early-stage rainwater, the distribution channel width is 200mm, it lays the quantity basis: calculate perpendicular transverse width, the transverse width of every 1.5m arranges a groove.
