Description

Early-stage rainwater is regulated and stored device

Technical field

The utility model relates to adjusts stream well and reservoir, particularly relates to early-stage rainwater and to regulate and store device.

Background technology

Early-stage rainwater, as the term suggests the rainwater just referring to the rainfall initial stage.Due to the rainfall initial stage, rainwater has dissolved the pollution gas such as a large amount of sour gas, vehicle exhaust, plant gas in air, behind landing ground, again owing to washing away asphalt felt roofing, asphalt concrete road, building site etc., make in early-stage rainwater containing pollutants such as a large amount of organic matter, pathogen, heavy metal, grease and suspended solids, therefore the degree of contamination of early-stage rainwater is higher, usually to exceed the degree of contamination of common municipal sewage.If early-stage rainwater is directly entered nature receiving waters, very serious pollution will be caused to water body.

Utility model content

The technical problems to be solved in the utility model is that the collection discharge of early-stage rainwater does not have special treating apparatus, provides a kind of early-stage rainwater to regulate and store device for this reason.

The technical solution of the utility model is: early-stage rainwater is regulated and stored device, it comprises one end is the dirty inlet port of rain, the other end is the quadrant pit of overflow pipe, described overflow pipe exit adaptation has overfall flap valve, the side of described quadrant pit is communicated with the effluent outfall with control valve, opposite side is communicated with reservoir by reservoir gutter and reservoir water inlet pipe, described reservoir gutter is positioned at below reservoir water inlet pipe, described reservoir gutter is positioned at above effluent outfall, described reservoir gutter and reservoir junction adaptation have reservoir flap valve, described reservoir gutter and quadrant pit junction adaptation have self-closing door, described reservoir water inlet pipe and quadrant pit junction adaptation have turnover door.

The improvement of such scheme is that described quadrant pit top also offers manhole.

The beneficial effects of the utility model are accumulated in reservoir by early-stage rainwater, carry out precipitation to regulate and store, after rainwater peak period, early-stage rainwater is discharged in soil pipe by storage pond delivery port, enter Sewage Plant to process, solve the problem that early-stage rainwater process is difficult, discharge difficulty etc., simultaneously for Wastewater Treatment Plant provides idle sewage quantity, reduce the wasting of resources.Decrease the bearing capacity of natural water equally, reduce the pollution of natural water.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described further.

As Fig. 1, Fig. 2, shown in Fig. 3, it is the dirty inlet port 4 of rain that the utility model comprises one end, the other end is the quadrant pit 11 of overflow pipe 3, described overflow pipe exit adaptation has overfall flap valve 9, the side of described quadrant pit is communicated with the effluent outfall 2 with control valve 1, opposite side is communicated with reservoir 7 by reservoir gutter 13 and reservoir water inlet pipe 12, described reservoir gutter is positioned at below reservoir water inlet pipe, described reservoir gutter is positioned at above effluent outfall, described reservoir gutter and reservoir junction adaptation have reservoir flap valve 8, described reservoir gutter and quadrant pit junction adaptation have self-closing door 6, described reservoir water inlet pipe and quadrant pit junction adaptation have turnover door 5.

The utility model forms by adjusting stream well and reservoir two parts, adjust stream well to comprise quadrant pit 11 and the effluent outfall 2 of carry potential overflow pipeline 3, the dirty inlet port 4 of rain and overfall flap valve 9, reservoir comprises reservoir flap valve 8, reservoir gutter 13 and reservoir water inlet pipe 12.When raining, as shown in Figure 4, do not have water or only have sewage to flow through in the dirty inlet port of rain, the water yield is less, and water level is lower than reservoir gutter, and current can only flow to Wastewater Treatment Plant by effluent outfall, through process up to standard after enter natural water; When raining, the initial stage as shown in Figure 5, and the control valve on effluent outfall is closed, and adjust water level in stream well then to rise fast, the self-closing door at reservoir gutter place closes rapidly; When adjust water level in stream well exceed under reservoir water inlet pipe along time, as shown in Figure 6, early-stage rainwater flows into reservoir, stores after full water until reservoir, and now reservoir water inlet pipe is closed by turnover door, prevents later stage rainwater from flowing into reservoir, adjusts the water level in stream well to continue to rise; When adjusting the water level in stream well to exceed overflow pipe, flowing into and adjusting the rainwater of stream well to be discharged by overfall flap valve, reach reverse-filling and the object of flood discharge smoothly; After rainfall terminates as shown in Figure 7, control valve on effluent outfall is opened, Wastewater Treatment Plant starts to dispose of sewage, adjust water level in stream well to start gradually to decline, when water level decreasing is to certain altitude, the self-closing door at reservoir gutter place opens automatically as shown in Figure 8, the early-stage rainwater stored in storage pond, flowed into by reservoir gutter gradually and adjust stream well, flow to Wastewater Treatment Plant and administer together with sewage, after up to standard, enter natural water.Storage time can need adjustment according to Wastewater Treatment Plant.

Adjust the position of each access and the setting of size of stream well in the utility model, the adjustment object of flow direction should be met, and make storage pond floor space minimum.

Reservoir gutter is higher than at the bottom of effluent outfall pipe, and difference in height can regulate according to sewage quantity, and reservoir water inlet pipe is lower than overflow pipe, and difference in height sets according to the design discharge of water inlet pipe.Native system is conducive to early-stage rainwater and regulates and stores in storage pond, is conducive to the improvement of Wastewater Treatment Plant to sewage and early-stage rainwater.

Check for the ease of attendant and adjust stream well, can also offer manhole 10 at quadrant pit top.In order to keep the safety in production, guardrail can be gone along with sb. to guard him around reservoir.
