Description

Integral type rainwater vatch basin
Technical Field
The invention relates to an integrated rainwater catch basin, and belongs to the technical field of water treatment.
Background
At present, the pollution problem of urban river and urban waterlogging problem frequently take place, and in the municipal works field, often set up the vatch basin in the confluence system pipe-line system and alleviate above-mentioned problem. The design of the intercepting well mainly comprisesRational determination of the adopted cut-off factor n0Multiple of closure n0Preferably, 2 to 5 are used.
However, the existing intercepting well has defects in structural design, such as:
intercepting multiple n of intercepting well0Once determined, the intercepting well cannot be changed, but with the development of cities, the designed intercepting well cannot meet the load caused by the increase of population and the increase of sewage. This makes the conventional intercepting well unable to effectively control the intercepting rate when in use. During rainstorm, part of sewage overflows into the river channel to cause pollution to water bodies to a certain degree. Moreover, the sewage treatment plant has limited treatment capacity, and a large amount of rainwater which does not need to be treated or river water which flows backwards into the intercepting pipe enters the sewage plant to impact each process structure of the sewage plant;
secondly, pollutants such as sludge, scum and garbage are often entrained in the sewage and the rainwater in the initial stage, and the accumulation of the pollutants such as the scum and the like in the past easily causes the blockage of a pipeline and influences the normal operation of a sewage interception system;
municipal sewer networks typically use gravity flow, so that the depth of burial of downstream pipes is typically greater than the depth of burial of upstream pipes. However, under certain special terrain conditions, the elevation of the pipe bottom of the downstream pipeline is higher than that of the pipe bottom of the upstream pipeline, so that sewage is only gathered but not drained, and waterlogging is possibly caused.
Disclosure of Invention
The purpose of the invention is as follows: the invention aims to solve the technical problem of providing an integrated rainwater catch basin, which not only can catch sewage and initial rainwater, but also can remove silt and organic matters in overflowing rainwater and sewage when the rainwater quantity is large, and can remove sediments in the basin through a dredge pump, so that the blockage of a downstream pipeline (namely a water outlet pipeline flowing into a river channel) is avoided; on the other hand still through setting up and cutting dirty room and set up latent dirty pump in cutting dirty indoor, solve the problem that sewage can't discharge into low reaches sewage pipe under the action of gravity.
In order to solve the technical problems, the technical means adopted by the invention is as follows:
an integrated rainwater intercepting well consists of an intercepting chamber, an overflow chamber and a sewage intercepting chamber; the intercepting chamber is respectively connected with a water inlet pipe and a sewage intercepting pipe, a gate is arranged at the inlet of the sewage intercepting pipe, and the intercepting chamber is communicated with the sewage intercepting chamber through the sewage intercepting pipe; an overflow weir is arranged on one side of the cutoff chamber close to the overflow chamber; a sleeve and a diversion cone fixed in the sleeve through a fixing column are arranged in the overflow chamber, an oxidation contact device is arranged on the sleeve in a surrounding mode, an annular groove is formed in the periphery of the oxidation contact device, and a gap of the annular groove is connected with a water outlet pipe; the interception chamber is connected with the diversion cone body through a connecting pipe; the sewage intercepting chamber is internally provided with a sewage submerging pump, the sewage submerging pump discharges sewage in the sewage intercepting chamber into a subsequent sewage pipeline through a sewage discharge pipe, and the sewage discharge pipe is provided with a gate valve.
The gate is an electric round gate, and a guide rail for moving the electric round gate is further installed on the inner wall of the intercepting chamber; the switch setting of electronic round gate is holding back the room outside, can adopt two kinds of modes of flashlight to open and close electronic round gate.
The height of the overflow weir is 1/3-1/2 of the height of the intercepting chamber, and the height of the overflow weir should meet the condition that the elevation of the top of the overflow weir is greater than the highest water level of the overflow chamber when the river rises tide in a sunny day and is 15-30 cm.
The tail end of the bottom of the overflow chamber along the water flow direction is arranged in a slope shape, the slope bottom of the slope is connected with a sludge suction pipe, and the other end of the sludge suction pipe extends out of the overflow chamber and is connected with a sludge suction pump.
Wherein, the flow guide cone body consists of a vertical section and a horn section.
The oxidation contact device is formed by enclosing an upper cover plate, a lower bottom plate, an inner ring circular shell and an outer ring circular shell, wherein the upper cover plate and the lower bottom plate are both of a net structure.
Wherein the oxidation contact device is filled with a filler; the filler is prepared by mixing the following components in parts by weight: 30-40 parts of PP, 20-25 parts of PVC, 15-20 parts of plant fiber, 12-16 parts of cellulose, 10-15 parts of acrylic resin, 6-8 parts of coupling agent, 5-8 parts of starch glue, 3-5 parts of expansive soil and 5-10 parts of attapulgite; the prepared filler is spherical, and the particle size of the spherical filler is 25-35 mm.

(2) according to the integrated catch basin, the connecting pipe is connected with the diversion cone, overflowing rainwater and sewage flows down in a vortex motion under the drainage action of the diversion cone, and meanwhile, the rainwater and sewage can form a larger vortex through the horn-shaped structure at the lower section of the diversion cone, so that sand-water mixtures can uniformly disperse and fall into a well bottom, mud and sand in the rainwater and sewage can be uniformly distributed at the bottom of the overflow chamber, the distribution state of the mud and sand in a mixed phase is improved, sand-water separation is better realized, and SS in the rainwater and sewage can be effectively removed;
(3) the sleeve in the integrated catch basin can weaken the kinetic energy of rainwater and sewage with higher flow velocity in the water inlet pipe, and avoids the influence on the hydrodynamic state of the indoor water body after the rainwater and sewage directly enter the overflow indoor water body, so that the sand-water separation efficiency is further improved, and the influence on the water passing capacity of the pipeline caused by the sediment entering the drainage pipeline and depositing in the pipeline is effectively avoided;
(4) according to the integrated intercepting well, the oxidation contact device is embedded in the upper part of the sleeve, the filler is filled in the oxidation contact device, when rainwater and sewage in the overflow chamber reach a certain degree, the rainwater and sewage enter the oxidation contact device and contact with the filler, heavy metals and organic matters (including macromolecular organic matters which are difficult to adsorb and degrade) in the rainwater and sewage can be effectively removed by utilizing the atmospheric reoxygenation function of the filler and the treatment of microorganisms attached to the surfaces of the filler and the filler, so that the pollution load of the rainwater and sewage is reduced, and the river entering amount of pollutants in the rainwater and sewage is effectively controlled;
(5) the submersible sewage pump arranged in the sewage intercepting chamber in the integrated intercepting well can solve the problem that the elevation of the bottom of a downstream pipeline is higher than that of the bottom of an upstream pipeline due to the limitation of topographic conditions in the actual construction process of a pipe network; the problem that sewage can not be discharged into a downstream sewage pipeline under the action of gravity is effectively solved.
