Description

Abandon class pond
Technical Field
The invention relates to the field of rainwater recycling engineering, in particular to a flow discarding pool.
Background
The water resource of China is in short supply, and along with the development of urban industrialization, the water resource crisis and the storm flood hazard of China are increasingly serious, and the available water is greatly reduced, so that rainwater is taken as an important water resource to be collected and utilized in an exemplary manner, the comprehensive treatment of the rainwater becomes a new problem which is widely concerned by the whole society, and meanwhile, the natural rainwater has the advantages of low hardness, less pollutants and the like, so that the rainwater is very suitable for collecting, processing and utilizing the rainwater, and the limited water resource is effectively saved.
But because there are more dirt such as dust on the road, the rainwater of initial stage erodees ground can bring more pollutant, and it is possible directly to discharge sewage in the inlet for stom water along the street shop simultaneously, and consequently the pollutant is more in the rainwater that the rainfall initial stage was collected, if discharge these sewage together in the rainwater collecting pit, can consume more manpower and materials and clear up the rainwater of collecting.
In order to solve the problem, people design an initial rainwater discarding pool to collect rainwater, the initial rainwater can be discharged into a sewage treatment device, and the later rainwater is discharged into a rainwater collecting device, so that the manpower, consumption and time required by rainwater cleaning are greatly reduced.
At present, chinese patent publication No. CN202380513U discloses a rainwater drainage pool, which includes a water inlet area, a drainage area, a rainwater purification collection area, and a drainage control device, wherein the water inlet area is communicated with the drainage area and the rainwater purification collection area, a liquid level sensor electrically connected to the drainage control device is disposed in the water inlet area for detecting a water level height in the water inlet area, a drainage outlet of the drainage area is disposed in the drainage area, and a drainage valve electrically connected to the drainage control device is disposed in the drainage area, and the drainage control device can control the drainage valve according to the water level height in the water inlet area detected by the liquid level sensor, so as to control the on-off of the drainage outlet of the drainage area.

Further setting: and a sewage discharge pipe is arranged in the sewage area, and the position of the sewage discharge pipe is higher than that of the sewage discharge pipe.
So set up, the sewage of rainfall initial stage is followed the sewage pipe of lower room and is discharged in the sewage district, discharges from the blow off pipe in the sewage district again, and consequently the height that highly is higher than the blow off pipe of sewage pipe can prevent that sewage from excessively building up when in the sewage district, and sewage flows back from the sewage pipe and flows back to lower indoor, and the sewage pipe lies in the position that the sewage district is close to the bottom surface simultaneously and can make things convenient for the discharge of sewage.
Further setting: the side walls of the lower chamber are isolated from the surrounding layer of soil by a layer of cement slurry.
So set up, the lateral wall of lower room sets up the fastness and the durability that the cement mortar layer can increase whole lower room, prevents that sewage from long-time erosion and leading to the damage of lower room, can prevent simultaneously that the moisture in the soil horizon on every side from permeating lower indoor, increases burden for whole class pond of abandoning.
Further setting: the bottom surface of the lower chamber is provided with a water permeable layer which is filled with a plurality of sand gravels and is provided with holes.
So set up, when the precipitation is great, the lower chamber holds fully easily, and if take place the secondary rainfall this moment, can have more impurity in the rainwater, and the ponding in the lower chamber this moment is more, and the through-hole is in starting and stopping mechanism, can make sewage get into rainwater strorage device, sets up the permeable bed in the bottom surface of lower chamber, can discharge very most sewage in the lower chamber through the filterable mode of soil for whole efficiency of abandoning the pond and discharging sewage.
Further setting: and a plurality of layers of geogrids between the permeable layer and the soil layer.
So set up, geogrid can prevent soil and grit in the soil layer from getting into the permeable stratum in, causes the jam on permeable stratum, can further improve the drainage efficiency on permeable stratum and the whole drainage efficiency who abandons the class pond from this, reaches more good result of use.
Further setting: the upper chamber is communicated with three rain pipes.
So set up, because when the precipitation is great, the inflow of rainwater can be far greater than the emission of rainwater, set up three downspout and can abandon a class body with more rainwater introduction to abandon class pond as the buffering of rainwater, the theory in cooperation sponge city increases the emission effect of rainwater.
Further setting: the structure of the sewage area is the same as that of the lower chamber.
So set up, when sewage got into more or sewage discharging system when the problem appears, sewage in the sewage district did not reach and discharges, probably leads to the backward flow of sewage, sets up the same with the structure of sewage district and lower room, can increase the speed that sewage district discharged sewage, improves the efficiency of whole class pond of abandoning from this.
Preferably, the diameter of the through hole is larger than that of the sewage pipe.
So set up, because the sewage volume that gets into the upper chamber can be greater than the volume that the lower chamber discharged sewage, consequently the diameter of through-hole is greater than the volume that gets into the sewage of lower chamber in the through-hole can be increased to the diameter of sewage pipe to avoid sewage to discharge too slowly and lead to the upper chamber to hold full sewage, prevent that sewage from getting into in the clear water pipe from the upper chamber.
In conclusion, the invention has the following beneficial effects:
can arrange the sewage at the precipitation initial stage and the clean moisture of later stage in the precipitation to abandon a class main part and need not set up too big volume, area is little, and this kind of abandoning class pond does not have comparatively complicated structure and setting simultaneously, and its cost of building is less, can also make things convenient for the operating personnel later stage to maintain it.
