Description
Technical field
The present invention relates to urban rainwater and process system regions, in particular to a kind of region burst rain processing system based on separate system pipe network.
Background technology
Current social, Development of Urbanization is increasingly rapider, and the area in city is increasing, and urban rainwater web frame becomes increasingly complex, and the processing pressure that urban rainwater processes system is increasing. At present, Urban Rainwater Pipe Networks is divided into three kinds: separate system, combined system and mixed flow system.
The separate system water treatment system of early stage has complete Storm Sewer Network structure, urban sewage system and Storm Sewer Network are kept completely separate, municipal sewage enters into either directly through sewage network and is collected in sewage disposal system and processes, Storm Sewer Network directly collects city rainwater drainage in natural water, and both do not connect and do not interfere with each other. The separate system Storm Sewer Network of early stage does not account for the problem that early-stage rainwater exists severe contamination, along with industrialized continuous progress, the pollution level of early-stage rainwater is increasingly severe, if early-stage rainwater not being carried out process and being directly discharged in natural water, natural water will be caused serious pollution.
Therefore, separate system Storm Sewer Network of the prior art is typically in certain region, city and builds a storage pond or Vatch basin structure, carries out process avoid being directly discharged in natural water by getting up to be transported to urban sewage treatment system by early-stage rainwater accumulation. Use the Storm Sewer Network structure of this separate system, can effectively early-stage rainwater be transported in urban sewage treatment system, early-stage rainwater is avoided to pollute Urban Natural water body, later stage clean rainwater is directly discharged to natural water and alleviates again the pressure of urban sewage treatment system, on whole rain water distribution, the Storm Sewer Network of this separate system has a lot of advantages, is more suitable for the use in existing city.
But it is as the continuous extension of city scope, there is very big defect in existing separate system Storm Sewer Network structure, existing city is typically in the structure of whole city and arranges the water treatment system that a few set is large-scale, the region area that often set water treatment system contains is too big, do not fully take into account rainwater time delay on pipeline or rainwash, first rain or be directly discharged to natural water to cause serious contamination accident, it is mix with substantial amounts of later stage clean rainwater to be flowed in sewage treatment plant and seriously increase the processing pressure of sewage treatment plant, for the regulation and control of early-stage rainwater and later stage rainwater unreasonable, can not be totally separated from. such as, storage pond has been built in the area near urban sewage treatment system in certain city, assuming that M area urban rainwater in this storage pond 1Km, M area is directly discharged to storage pond by pipe network, it is T1 that the city initial rainwater in M area is fully discharged into time of storage pond. for the area farther out of the distance storage pond beyond this region, it is assumed that it is T2 that the city initial rainwater that air line distance is 10km, N area of N area distance storage pond is fully discharged into the time of storage pond, and from time length, T2 to be obviously far longer than T1. and after storage pond is collected and expired early-stage rainwater, the rainwater exceeded begins to be automatically discharged in natural water, storage pond is T3 from starting to collect rainwater to the time started to natural water discharge. during actual motion, iff the rainwater emission behaviour taking M area into account, namely regional for M early-stage rainwater can enter into the clean rainwater of sewage disposal system intermediary and later stages by storage pond and can be discharged in natural water, need T3 more than T1, once beyond T3, storage pond immediately discharges to natural water, and now N area flows to the rainwater of storage pond and still pollutes very serious early-stage rainwater, namely T3 is less than T2, can cause very serious pollution undoubtedly to natural water discharge.
Iff the rainwater emission behaviour considering N area, namely T3 is more than T2, and the early-stage rainwater in that N area can enter in urban sewage treatment system by storage pond, is well processed. But for M area, M area has substantial amounts of later stage clean rainwater to be also discharged in urban sewage treatment system within the time of the early-stage rainwater in storage pond discharge N area, and such emission behaviour can cause very big processing pressure to urban sewage system. It addition, M area is generally, with the pipe network in N area, the situation of connection during actual motion, due to the difference of distance, the delay effect on road, the later stage clean rainwater that the early-stage rainwater in N area may be regional for severe contamination M, also result in the unreasonable of rainwater emission behaviour.

The discharge end of the rainwater arm 20 in each section 18 connects with rainwater treatment facility, processes being discharged into rainwater treatment facility after the rainwater-collecting in section 18, is discharged into natural water 1 after having processed. The rainwater arm 20 of the present invention does not connect with branch sewer 19 and common sewer 21, for complete separate system. Early-stage rainwater is collected by rainwater treatment facility. Rainwater treatment facility is abandoned stream well, Vatch basin, storage pond or functional rain water treatment facilities.
The entrance point of the rainwater treatment facility of the present invention connects with the discharge end of rainwater arm 20, and its discharge end is divided into discharge purified water end and sewage discharge end, and the discharge of discharge purified water end is later stage clean rainwater, connects with natural water 1. The early-stage rainwater of sewage discharge end discharge, early-stage rainwater is seriously polluted, early-stage rainwater is processed by the present invention by two ways, one is carry out comprehensive control either directly through being transported to sewage treatment plant 17 in discharge of pipes to common sewer 21, for direct abandoned stream pattern, another kind is to be processed in device by discharge of pipes to first rain to process, and the clean water after process is discharged into natural water 1, for shunt mode. Therefore, the sewage discharge end of the rain processing system of the present invention has two kinds of tupes, now by two embodiments, the water treatment system of the present invention is illustrated.
Embodiment 1: as it is shown in figure 1, the first rain of the present embodiment is directly discharged to abandoned stream in common sewer 21, carry out integrated treatment by sewage treatment plant 17, the present embodiment arranges total storage pond 23 between the port of export and the entrance point of sewage treatment plant 17 of common sewer 21. During practical application, the disposal ability of sewage treatment plant 17 is fixed value, and when raining, separate system pipe network is abandoned stream, and namely just rain is directly discharged in sewage treatment plant 17 to process, and the pressure of sewage treatment plant 17 sharply strengthens, and can seriously exceed its treating capacity. Therefore the present embodiment sets up total storage pond 23 before the entrance point of sewage treatment plant 17, storage just rain is collected by total storage pond 23, after sewage treatment plant 17 processing pressure reduces or rainfall rests, the more first rain in total storage pond 23 is carried out integrated treatment by equipment exhaustings such as immersible pumps to sewage treatment plant 17. The abandoned stream structure of the present embodiment is abandoned stream well 22.
As shown in Figure 11��12, the present embodiment includes well body, mud chamber 28 is set in well body, the separate chamber in buoyancy tank room 29 and 30 3, float chamber, mud chamber 28 connects water inlet pipe 26, buoyancy tank room 29, float chamber 30 connects outlet pipe 27 jointly, float chamber 30 connects abandoned stream pipe 25, abandoned stream pipe 25 mouth of pipe is respectively lower than water inlet pipe 26, outlet pipe 27 mouth of pipe, the first overfall 33 is had between mud chamber 28 and buoyancy tank room 29, the second overfall 34 is had between mud chamber 28 and float chamber 30, the area of the first overfall 33 is less than the area of the second overfall 34, first overfall 33, second overfall 34 is above abandoned stream pipe 25 mouth of pipe, buoyancy tank 32 it is provided with in buoyancy tank room 29, the abandoned stream passage 39 to abandoned stream pipe 25 and the ball float 31 that 39 mouthfuls of abandoned stream passage can be covered it is communicated with in float chamber 30, the weight of buoyancy tank 32 is more than the weight of ball float 31, it is connected by connecting device between buoyancy tank 32 with ball float 31.
First barricade 37 and the second barricade 38 of orthogonal vertical layout is set in well body, mud chamber 28 is surrounded between wall in first barricade 37 and well body, surround buoyancy tank room 29 between wall in a part for first barricade 37, the second barricade 38 and well body, in another part of the first barricade 37, the second barricade 38 and well body, between wall, surround float chamber 30. First overfall 33 is opened in a part for the first barricade 37, and the second overfall 34 is opened on another part of the first barricade 37.
Having sewage overflow mouth 40 in dry season bottom second overfall 34, dry season, sewage overflow mouth 40 was offered lower than the second overfall 34. Dry flow sewage during fine day enters abandoned stream well by water inlet pipe 26, after mud chamber 28 is precipitated, enters float chamber 30 by dry flow sewage overfall 17, discharges again through abandoned stream pipe 25. Owing to dry flow sewage overfall 17 height is lower than the second overfall 34 and the first overfall 33, dry flow sewage will not enter buoyancy tank room 29, and buoyancy tank room 29 spilled water hole 12 can be avoided to block.
