Description
Technical Field
The invention relates to the technical field of sewage intercepting wells, in particular to a sewage intercepting well for treating a sewage discharge outlet of black and odorous water and a construction process thereof.
Background
At present, a sewage intercepting well is a well rebuilt near a blocked and aged sewage well, and is communicated with a sewage pipeline, so that larger impurities in sewage can be intercepted by the sewage intercepting well.
The prior Chinese patent with reference to publication number CN206319401U discloses a sewage intercepting well, which comprises: the sewage intercepting outlet, the overflow outlet and the water inlet are respectively communicated with the cavity; and the baffle is arranged on the inner wall of the cavity and forms a notch, and the baffle is arranged between the water inlet and the sewage interception outlet and is close to the overflow outlet. This cut dirty well reposition of redundant personnel is effectual, avoids a large amount of rainwater to flow into sewage treatment plant, has increased sewage treatment plant's operational load.
The above prior art solutions have the following drawbacks: when a large amount of rainwater enters the water inlet in rainy days, most of the rainwater moves to the overflow outlet along the partition plate and flows out, and a part of solid domestic garbage without water can be driven to flow out from the overflow port, so that the part of solid domestic garbage which flows out from the overflow port and is possibly carried in the water can pollute rivers and the like.
Disclosure of Invention
The invention aims to provide a sewage intercepting well for treating a black and odorous water body sewage outlet, which ensures that solid domestic garbage is not easily carried in water flowing out of an overflow port.
The above object of the present invention is achieved by the following technical solutions:
the utility model provides a black and odorous water drain renovation is with cutting dirty well, includes the pit shaft, and overflow mouth, water inlet and cut dirty export have been seted up to the pit shaft, and overflow mouth and water inlet level just are just right, and the cut dirty export is located the below of water inlet, vertical sliding connection has a filter screen section of thick bamboo in the pit shaft, and the entry with water inlet looks adaptation is seted up to the filter screen section of thick bamboo, and the bottom that the bottom of filter screen section of thick bamboo is close to the water inlet is first filter house, and the lateral wall of filter screen section of thick bamboo is the second filter house, along the direction of keeping away from the water inlet, and the bottom of filter screen section of thick bamboo is provided with separation portion, and separation portion begins from the one end that the water inlet was kept away from to first filter house, upwards inclines gradually, fixedly connected with the.
By adopting the technical scheme, in rainy weather, a large amount of rainwater enters the water inlet, sewage is heavier at the lower part of the water flow, the rainwater is at the upper part of the water flow, the water flow is larger at the moment, the water flow enters the shaft from the water inlet, then passes through the inlet to enter the filter screen cylinder, and the sewage directly passes through the first filter part, then falls into the lower part of the clapboard from the gap and flows into a sewage treatment plant from the overflow port, the rainwater rushes up the blocking part, in the process that the rainwater washes the blocking part, the solid domestic garbage is heavier and is not easy to move upwards together with the rainwater to wash the blocking part, the blocking part has a certain blocking effect on the solid domestic garbage, the possibility that the solid domestic garbage flows to the overflow port is reduced, meanwhile, when the rainwater flows out from the overflow port, the rainwater needs to pass through the filter screen cylinder and can be further filtered by the side wall of the filter screen cylinder, so that the effect that solid domestic garbage is not easily carried in the water flowing out from the overflow port is achieved.
The invention is further configured to: the filter screen cylinder is provided with arc portion, and arc portion begins to be the arc from separation portion top and extends to overflow mouth bottom, and the curved inboard of arc portion is just to the overflow mouth.
Through adopting above-mentioned technical scheme, when rivers are great, the rainwater can dash separation portion, and the rainwater falls to arc portion after dashing separation portion top, and arc portion can produce the guide effect to the rainwater, makes the rainwater can follow vertical flow and become horizontal flow gradually, has reduced the impact of rainwater to arc portion.
The invention is further configured to: the position fixedly connected with barb of separation portion top.
Through adopting above-mentioned technical scheme, the rainwater dashes upward separation portion and then flows from the overflow mouth, smuggles solid domestic waste secretly in the rainwater when, and the barb can be hung solid domestic waste, can further avoid solid domestic waste to flow from the overflow mouth.
The invention is further configured to: the separation portion is provided with the horizontally supporting part between the lowest of portion and the first filter house, and the supporting part flushes with the lowest of water inlet.
Through adopting above-mentioned technical scheme, the setting of supporting part for the baffle is comparatively stable to the support of filter screen section of thick bamboo.
The invention is further configured to: first filter house is including holding the material lateral wall and filtering the diapire, holds the material lateral wall and begins vertical downwardly extending from the one side that the supporting part is close to the water inlet, filters diapire fixed connection in the bottom of holding the material lateral wall.
Through adopting above-mentioned technical scheme for first filter house can hold more solid-state domestic waste, can reduce the frequency of regularly clearing up.
