Description
Technical Field
The utility model relates to the technical field of rural sewage treatment engineering, in particular to a courtyard type multifunctional inspection well for rural sewage treatment.
Background
With the continuous acceleration of rural domestic sewage treatment speed, the problem of difficult operation and maintenance is increasingly outstanding, and more rural sewage pipe networks become blocked after running for a long time, and the phenomenon of incapability of normal operation occurs. The rural sewage collection pipe network has low pipeline flow rate due to the characteristics of decentralized population, low aggregation density and low sewage discharge coefficient in rural areas of China; while the seasonal fluctuation of the sewage discharge amount of villages with large population flows is large; the sewage quantity of the travelling village is obviously changed along with the travelling slack season and the busy season, and the sewage impurity is more, so that when the water quantity of a rural sewage pipe network is smaller and the flow velocity is lower, large-particle pollutants in the pipeline are easy to deposit in the pipeline, and the water passing area of the pipeline is easy to gradually reduce in the long time, and finally the pipeline is blocked. In addition, domestic sewage is generally lack of carbon sources, and the method of canceling the septic tank is popularized and applied, so that the risk of clogging of rural domestic sewage pipes is increased.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a courtyard type multifunctional inspection well for rural sewage treatment, which can effectively remove various impurities in a sewage pipeline, provide guarantee for normal operation of a sewage pipe network, and improve the operation effect and the service life of rural sewage treatment facilities.
In order to solve the technical problems, the courtyard type multifunctional inspection well for rural sewage treatment comprises a sewage inlet pipe, a sewage outlet pipe, a shaft and a well cover, wherein the top end of the shaft is provided with a well ring, the well cover is arranged on the top surface of the well ring, the sewage inlet pipe and the sewage outlet pipe are respectively arranged on two sides of the shaft and above the bottom surface of the shaft, the shaft forms a bottom mud settling chamber below the sewage inlet pipe and the sewage outlet pipe, and a grid filter screen is arranged at the inlet of the sewage outlet pipe through a screen cover body.
Further, the depth of the bottom hole mud settling chamber is 500-600 mm.
Further, the inspection well further comprises an anti-falling net, expansion bolts with hooks are embedded in the inner wall of the well ring at intervals, and the periphery of the anti-falling net is hooked on the hooks of the expansion bolts.
The courtyard type multifunctional inspection well for rural sewage treatment adopts the technical scheme that the inspection well comprises a sewage inlet pipe, a sewage outlet pipe, a shaft and a well cover, wherein the top end of the shaft is provided with a well ring, the well cover is arranged on the top surface of the well ring, the sewage inlet pipe and the sewage outlet pipe are respectively arranged on two sides of the shaft and above the bottom surface of the shaft, the shaft forms a bottom mud settling chamber below the sewage inlet pipe and the sewage outlet pipe, and a grid filter screen is arranged at the inlet of the sewage outlet pipe through a screen cover body. The inspection well can effectively remove various impurities in the sewage pipeline, provide guarantee for normal operation of a sewage pipe network, and improve the operation effect and the service life of rural sewage treatment facilities.
Drawings
The utility model is described in further detail below with reference to the attached drawings and embodiments:
FIG. 1 is a schematic view of a courtyard type multifunctional manhole for rural sewage treatment according to the present utility model.
Detailed Description
Embodiment as shown in fig. 1, the courtyard type multifunctional inspection well for rural sewage treatment comprises a sewage inlet pipe 3, a sewage outlet pipe 4, a shaft 1 and a well cover 2, wherein the top end of the shaft 1 is provided with a well ring 11, the well cover 2 is arranged on the top surface of the well ring 11, the sewage inlet pipe 3 and the sewage outlet pipe 4 are respectively arranged on two sides of the shaft 1 and are positioned above the bottom surface of the shaft 1, the shaft 1 forms a bottom mud settling chamber 12 below the sewage inlet pipe 3 and the sewage outlet pipe 4, and the inlet of the sewage outlet pipe 4 is provided with a grid filter screen 42 through a screen cover body 41.
Preferably, the depth of the bottom hole mud settling chamber 12 is 500-600 mm. The depth ensures that the sludge and large-particle solids are precipitated in a bottom hole sludge settling chamber, and can be conveniently cleaned regularly.
Preferably, the inspection well further comprises an anti-falling net 5, expansion bolts 51 with hooks are embedded in the inner wall of the well ring 11 at intervals, and the periphery of the anti-falling net 5 is hooked on the hooks of the expansion bolts 51. The anti-falling net is used for improving the safety of the inspection well and avoiding falling accidents after the well lid is shifted or damaged.
The inspection well is mainly composed of a shaft 1 with a mud settling chamber 12 and a sewage outlet pipe 4 with a grid screen, when rural sewage enters the shaft through a sewage inlet pipe 3, sludge and large-particle solids are precipitated in the mud settling chamber at the bottom of the shaft, and garbage suspended in the sewage, such as toilet paper, plastic bags and the like, is intercepted when flowing to the grid screen 42 at the inlet of the sewage outlet pipe 4, so that the sewage in the sewage outlet pipe is ensured to be free of impurities, the blockage of a sewage main pipe is prevented, and the normal operation of a sewage discharge system is ensured. Meanwhile, the sludge and large-particle solid matters precipitated in the sludge settling chamber 12 can be cleaned regularly, so that the sewage inlet pipe 3 and the sewage outlet pipe 4 are prevented from being blocked.
The inspection well is simple in structure and various in functions. The filter has the functions of precipitation and filtration, and has certain effect of removing fine substances such as fine sand grease and the like while removing various large-particle impurities; and the cost is lower, has little difference with the common inspection well, and accords with rural economic conditions. The operation and maintenance are convenient and quick. The inspection well is only required to be properly salvaged, dredged and maintained regularly, and large-scale equipment is not required to be cleaned. The inspection well has multiple functions of sedimentation and filtration, can carry out sedimentation and filtration treatment on rural sewage, reduces the risk of clogging of a sewage pipeline, and provides a guarantee for normal operation of subsequent sewage treatment equipment.
