Examples

Referring to fig. 1-2, the present embodiment provides an integrated sewage treatment apparatus. The integrated sewage treatment device comprises: a septic tank, a grid well, an adjusting tank, a biological tank and a disinfection discharge tank which are sequentially communicated by a sewage channel.

The well of the grille well is vertically arranged, the water inlet 100 of the grille well is arranged close to the top, and the water outlet 200 of the grille well is arranged close to the bottom. The middle part of the grid well is also provided with a yielding groove 300, and the yielding groove 300 is formed by the inner side wall of the grid well along the radial direction of the well.

The grid well is further provided with a conveyor belt 400, the conveyor belt 400 being arranged obliquely. The bottom end of the conveyor belt 400 extends to the relief groove 300, and the top end extends to the outside of the grid well. The conveyor belt 400 is a mesh belt, the mouth of the abdicating groove 300 is provided with a mesh plate 310 for blocking garbage, and the mesh plate 310 is positioned on one side of the conveyor belt 400 close to the bottom of the grid well.

The integrated sewage treatment device is mainly designed for comprehensive domestic sewage such as public sewage, domestic sewage and the like of workers. In the process of sewage treatment, domestic sewage enters the integrated sewage treatment device from the septic tank and is subjected to primary treatment by the septic tank. The sewage treated by the septic tank enters the grid well subsequently to remove soft entanglement, larger solid particle impurities and floating objects in the sewage, thereby reducing the system treatment workload. The sewage filtered by the grid well enters the regulating tank to regulate and homogenize the water quantity and the water quality of the sewage, so that the balance and the stability of the water quantity and the water quality of a subsequent treatment unit are ensured. In the regulating tank, organic matters in the sewage can be degraded to a certain extent, so that the shock resistance and the treatment effect of the whole system are improved conveniently. And after the sewage well regulating reservoir is regulated, the sewage enters a biological tank, in the biological tank, the sewage is sequentially treated by facultative microorganisms and an mbr membrane bioreactor, the facultative microorganisms are used for converting insoluble organic matters in the sewage into soluble organic matters and hydrolyzing macromolecular organic matters into micromolecular organic matters, so that the mbr membrane bioreactor can further treat the sewage. After the treatment of the biological tank is finished, the sewage is uniformly put into a disinfection discharge tank, and the water body is disinfected to reach the discharge standard. The water body after reaching the standard can be selectively discharged or recycled.

When sewage passes through the grid well, the sewage flows to the conveyor belt 400 from the water inlet 100, and soft winding objects, larger solid particle impurities and floating objects in the sewage can be smoothly filtered out by the mesh belt. The conveying direction of the conveyor belt 400 is controlled so that the conveyor belt 400 conveys the filtrate to the outside of the grid well for uniform collection and treatment. The filtered sewage enters the bottom of the grid well and enters the regulating tank through the water outlet 200. It should be noted that, the continuous output of the filtered material by the conveyor belt 400 can avoid the filtered material from depositing in the grid well, effectively reduce the load of the grid well, and facilitate the continuous and stable filtering operation of the grid well, thereby effectively reducing the frequency of shutdown maintenance and cleaning.

It should be noted that, in the filtering process, there is hardly a very small amount of filtered substances to slide down along the belt surface of the conveyor belt 400, and at this time, the slid filtered substances will slide into the abdicating groove 300 and be blocked in the abdicating groove 300 by the net plate 310, and will not fall into the bottom of the grid well, so as to avoid mixing into the regulating tank from the water outlet 200, and effectively ensure the stability of the subsequent processes. When enough filtrate is accumulated in the concession slot 300, the garbage in the concession slot 300 is treated uniformly.

In general, the grid well of the integrated sewage treatment device is optimized, so that the integrated sewage treatment device has better self-cleaning capability, the shutdown maintenance frequency is effectively reduced, the integrated sewage treatment device has positive significance for improving the treatment efficiency, and the shutdown maintenance cost of a small-sized treatment plant is obviously reduced.

Further, referring to fig. 3, the belt surface of the conveyor belt 400 is further provided with auxiliary filter screens 410, and the auxiliary filter screens 410 are uniformly spaced along the length direction of the conveyor belt 400. The auxiliary filter screen 410 is composed of filter wires distributed in a linear array in the width direction of the conveyor belt 400, and the filter wires include a first straight filter section 411, an arc-shaped section 412, and a second straight filter section 413 connected in sequence.

Wherein, the one end of first straight type filter segment 411 and the second straight type filter segment 413 are all connected with the band face of conveyer belt 400, and first straight type filter segment 411 is perpendicular to the band face setting of conveyer belt 400, and second straight type filter segment 413 is the slope setting for the band face of conveyer belt 400, and the one end of keeping away from the band face of conveyer belt 400 of first straight type filter segment 411 and second straight type filter segment 413 is connected by arc section 412. In the upstream section 420 of the conveyor 400, the first straight filter segment 411 is located on the upstream side of the second straight filter segment 413. The central axes of the first straight filter segment 411, the arc segment 412 and the second straight filter segment 413 are located on the same plane and perpendicular to the belt surface of the conveyor belt 400.

It should be noted that, the gap between two adjacent filter wires in the same set of auxiliary filter screen 410 can be flexibly selected according to actual needs, and in general, the proper distance is selected according to the size of the filtrate, so as to prevent the filtrate from sliding down from the gap between two adjacent filter wires.

Through the design, the auxiliary filter screen 410 can effectively prevent the filtered matter from sliding down along the belt surface of the conveyor belt 400, so that the amount of the filtered matter entering the abdicating groove 300 is further reduced, the time interval for cleaning the abdicating groove 300 is further enlarged, and the cleaning frequency is reduced. Meanwhile, the filtering capacity of the conveyor belt 400 for soft winding materials can be improved. The arrangement of the filter wires of the auxiliary filter screen 410 is also convenient for the soft winding to smoothly slide down when entering the descending section 430 (at the upper end of the conveyor belt 400) from the ascending section 420 of the conveyor belt 400, so as to collect the filtered materials uniformly.

In this embodiment, the first straight filter segment 411 further has a plurality of blocking pillars 440, the blocking pillars 440 extend toward a side away from the second straight filter segment 413, and the plurality of blocking pillars 440 are uniformly spaced along the length direction of the first straight filter segment 411. The top wall of the blocking pillar 440 is a convex spherical wall, and the radius of the spherical surface corresponding to the spherical wall is the same as the radius of the blocking pillar 440. When the auxiliary filter screen 410 moves to the downstream section 430 of the conveyor belt 400, the blocking post 440 faces vertically downward. In order to make the filtered materials easily fall off from the conveyor belt 400, the surfaces of the conveyor belt 400, the auxiliary filter screen 410 and the barrier pillars 440 are all treated with corrosion prevention and smoothing.

With further reference to fig. 4, the integrated sewage treatment device further includes a flushing nozzle 500 and a garbage transfer belt 600. The head 500 is in the form of a strip with a plurality of holes along its length, and the length of the holes is slightly greater than the width of the belt 400. The two groups of flushing nozzles 500 are arranged along the width direction of the conveyor belt 400, the flushing nozzles 500 are arranged between the ascending section 420 and the descending section 430 of the conveyor belt 400, the water spraying direction of one group is perpendicular to the belt surface of the conveyor belt 400 and faces the descending section 430, and the water spraying direction of the other group is vertical downward and faces the descending section 430. The garbage conveying belt 600 is a V-shaped rubber conveying belt for collecting the filtrate. The flush head 500 is in communication with an external water pump.

Through the design, the blocking column 440 can further enhance the blocking effect of the auxiliary filter screen 410 on garbage (especially soft entanglement) and reduce the direct impact of the garbage on the belt surface of the conveyor belt 400, so that the soft entanglement is prevented from being blocked in the meshes of the conveyor belt 400 under the impact of the sewage in the water inlet 100. On the other hand, after the solid waste is transferred from the upper stage 420 to the lower stage 430, the filtrate falls into the waste conveyor 600. At this time, the blocking column 440 is vertically downward, which facilitates the smooth sliding of the soft winding along the blocking column 440, and greatly improves the separation effect of the filtrate. When the filtered materials are separated, the separation of the filtered materials is promoted by matching with the scouring action of the upper water-flushing nozzle 500, and the garbage blocked in the meshes of the conveyor belt 400 can be effectively flushed out, so that the normal filtering capacity of the conveyor belt 400 is ensured.

Further, a group of the water spray heads 500 spraying water in a direction perpendicular to the belt surface of the conveyor belt 400 is located at a position upstream of the lower segment 430 of the group of the water spray heads 500 spraying water vertically downward. Through the design, the garbage (mainly soft winding objects) still adhered to the conveyor belt 400 is washed by the group of flushing nozzles 500 with the water spraying direction perpendicular to the belt surface of the conveyor belt 400, so that the filtered objects are separated from the belt surface, part of the winding objects can directly fall off to the garbage conveyor belt 600, and part of the winding objects can slide along the first straight filter section 411 and is blocked by the blocking column 440.

Then, the filtered materials are flushed by the group of flushing nozzles 500 which are vertically downward in the water spraying direction, so that the soft materials which are blocked or wound on the blocking columns 440 can be smoothly flushed, and the filtered materials can completely and smoothly enter the garbage conveying belt 600.

The flush water sprayed from the flush head 500 and the filtered matter falling from the conveyor 400 are collected by the garbage conveyor 600, and the filtered matter can be smoothly conveyed along the garbage conveyor 600 (especially, the soft winding matter can be prevented from adhering to the garbage conveyor 600) under the wetting and pushing actions of the flush water, so that the filtered matter can be smoothly conveyed away.

Further, the tail end of the garbage conveying belt 600 is provided with a dense screening plate 700 for filtering garbage, and the screening plate is erected on a recovery port 810 of the flushing water recovery tank 800, as shown in fig. 5. The filtered matter and the flushing water guided out by the garbage conveying belt 600 are filtered by the compact sub-sieve plate 700, the flushing water smoothly returns to the flushing water recovery tank 800 so as to be repeatedly used by the flushing sprayer, and the filtered matter stays on the compact sub-sieve plate 700, so that the filtered matter and the flushing water are uniformly collected and processed.

In this embodiment, the mesh plate 310 is detachably installed in the receding groove 300, and the groove wall of the receding groove 300 close to the bottom of the grid well is inclined, and one end of the receding groove 300 close to the groove bottom is higher than one end of the receding groove 300 close to the notch. By this design, when excessive filtrate is deposited in the abdicating groove 300 (which generally takes a long time), it is possible to choose to stop the machine, remove the mesh plate 310, and flush the filtrate in the abdicating groove 300 out along the inclined wall of the abdicating groove 300 with water for uniform collection with the mesh plate 310 box.

In conclusion, the grid well of the integrated sewage treatment device is optimized, so that the integrated sewage treatment device has better self-cleaning capability, the frequency of shutdown maintenance is effectively reduced, the integrated sewage treatment device has positive significance for improving the treatment efficiency, and the shutdown maintenance cost of a small-sized treatment plant is obviously reduced.
