[0020] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of systems consistent with some aspects of the utility model as detailed in the attached claims.

[0021] In order to solve the problems of substandard sewage quality discharged into the municipal sewage main pipe and difficult supervision in the prior art, this embodiment provides a sewage discharge monitoring system, which is set at the place where the enterprise pressure sewage pipe is connected to the municipal sewage main pipe, such as Figure 1 and 2 As shown, it includes an inspection well, an electric control box, a partition wall 8, and a valve control unit, an energy dissipation sampling unit, and a water outlet unit are sequentially arranged along the flow direction of sewage;

[0022] The inspection well is divided into two areas: inspection well area 1 and inspection well area 2;

[0023] The valve control unit is arranged in the first area of ​​the inspection well, and the energy dissipation sampling unit and the water outlet unit are arranged in the second area of ​​the inspection well; the valve control unit and the energy dissipation sampling unit correspond one to one, and multiple groups are arranged;

[0024] The partition wall 8 is arranged perpendicular to the bottom of the second inspection well area and arranged from the bottom to the top of the well, dividing the well space in the second inspection well area into multiple groups of units, each unit being a group of sampling modules;

[0025] The valve control unit includes a water inlet pipe, a water inlet flange 2, a manual control valve 3, and an electric control valve 4. The water inlet end of the water inlet pipe is provided with a water inlet flange 2. According to the water inlet direction, the manual control valve 3 and the electric control valve 4 are sequentially installed on the water inlet pipe; the water inlet end of the water inlet pipe is connected to the enterprise pressure drainage pipe, and the water outlet end pipe elbow of the water inlet pipe extends out of the inspection well zone 1 and is located in the inspection well zone 2;

[0026] The energy dissipation sampling unit includes a sampling bottle 5, a retaining wall 7, a partition wall 8, a sampling hole and a cover plate 12. The sampling hole is arranged at the top plate of the inspection well. The cover plate 12 is covered on the sampling hole in a flat opening manner. The sampling bottle 5 is connected to the outer side of the cover plate 12 by a hemp rope. The retaining wall 7 is arranged perpendicular to the bottom of the inspection well and is installed on the opposite side of the outlet end of the water inlet pipe. The retaining wall 7 is higher than the height of the elbow of the outlet pipe. The outer side of the retaining wall 7 is a water outlet unit. A water outlet pipe is arranged in the water outlet unit. The water outlet pipe is connected to the downstream municipal sewage pipe; the water outlet pipe 9 is connected to the downstream municipal sewage pipe by gravity flow. The electric control box is arranged outside the inspection well.

[0027] The working principle of the above-mentioned energy dissipation sampling unit is: during normal operation, the manual control valve 3 and the electric control valve 4 are in the open state, and the incoming water flows downward through the pipe elbow into the bottom of the second area of ​​the inspection well. The erosion-resistant layer at the bottom can prevent the sewage from eroding the well body and the well wall. The sewage overflows through the top of the retaining wall 7 to the subsequent water outlet part, which has the effect of energy dissipation. The function of the partition wall 8 is to prevent sewage from different sources from mixing with each other, and finally the gravity flow is connected to the downstream municipal sewage pipe through the outlet pipe 9.

[0028] The electric control box 10 is connected to the electric control valve 4 via a cable.

[0029] Ductile iron anti-theft manhole covers 11 are respectively provided on the top of the inspection well body, the valve control unit and the water outlet unit area.

[0030] A scour-resistant layer is provided at the bottom of the second area of ​​the inspection well.

[0031] The present embodiment provides a sewage discharge monitoring system, which is convenient for testing water samples and controlling switches. When testing water samples, the cover plate 12 is opened, and the sewage samples in the sub-grids formed by each energy dissipation sampling unit are taken through the sampling bottle 5. After the water sample is tested, for the sewage with unqualified water quality, the corresponding electric valve 4 can be controlled to be closed through the electric control box 10 to prevent the sewage with unqualified water quality from being discharged into the municipal sewage pipe. When the electric valve 4 fails, the sewage can be temporarily cut off through the manual valve 3, and the electric valve 4 can be repaired or replaced.

[0032] Those skilled in the art will readily come up with other embodiments of the present invention after considering the specification and practicing the utility model disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary technical means in the art that are not disclosed in the present invention.

[0033] It should be understood that the present invention is not limited to the precise structure described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.
