Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hazardous waste treatment, in particular to a sewage dredging integrated system. BACKGROUND

[0002] The sewage generated in the chemical plant area includes chemical sewage and domestic sewage, both of which do not have the condition of direct discharge, so related treatment is needed to reach the discharge standard.

[0003] In related technologies, biological oxidation treatment is one of the most common sewage treatment methods, which uses the metabolic activity of microorganisms to degrade and remove organic matter and other pollutants in sewage, so that the sewage meets the discharge standard.

[0004] In view of the above related technologies, microorganisms degrade organic matter through metabolic activity, and the degraded organic matter forms a sediment material, which is similar to sludge, that is, a solid-liquid mixture, and cannot be directly collected due to its high water content. Therefore, a treatment system is needed to enable the sludge to be treated in the subsequent link of sewage treatment so that it can be easily collected and cleaned. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the problem that the treatment of the separated product is cumbersome and reduce the cost of sewage treatment, the present application provides a sewage dredging integrated system.

[0006] The sewage dredging integrated system provided by the present application adopts the following technical scheme:

[0008] The lower part of the sedimentation tank is integrally connected with a sedimentation hopper for settling flocculants, the sedimentation tank is provided with a dredging mechanism above for treating sludge in communication with the sedimentation hopper, and the sedimentation hopper is provided with a waste pipe on one side for passing the sediment material into the dredging mechanism.

[0009] By adopting the technical scheme, multiple pool bodies with different functions but interconnected are arranged in the system, the storage tank is used for temporarily storing sewage, the overflow pool removes impurities in the sewage by means of the medicament introduced by the medicament barrel, the sedimentation pool can settle flocculation in the sewage, and the clean water pool can receive dischargeable water, so that a complete sewage purification process is formed, the chemical sewage and domestic sewage generated in the chemical plant area can be gradually treated, and finally the discharge standard is reached to meet the discharge requirement. For the sludge-like precipitated material formed by the organic matter in the sewage after microbial metabolic degradation, a settling hopper is arranged at the lower part of the sedimentation pool to collect the settled flocculation, and a dredging mechanism and a waste pipe connected with the settling hopper are used to treat the sludge, so that the sludge can be conveniently collected and cleaned up, and the problem of complicated treatment of the separated product in the prior art is solved.

[0010] Further, the dredging mechanism comprises a filter press arranged on the dredging platform above the sedimentation pool, the filter press comprises a filter press body and vertical plates symmetrically supported on both sides of the filter press body, the waste pipe penetrates through the vertical plates and is in communication with the filter press body, a liquid discharge pipe for outputting filtered waste liquid is arranged at a position adjacent to the waste pipe on the vertical plate, one end of the liquid discharge pipe penetrates through the vertical plate and is in communication with the filter press body, and the other end of the liquid discharge pipe away from the filter press body extends into the overflow pool.

[0011] By adopting the technical scheme, in the dredging mechanism, the filter press can separate the solid and liquid in the sludge by extrusion or other ways, so that the sludge with a high water content and difficult to be directly collected is changed into a state with a higher solid content and more convenient for subsequent treatment and collection, the treatment difficulty of the sludge is improved, and the treatment efficiency of the sludge in the entire sewage treatment system is improved. The waste pipe penetrates through the vertical plate and is in communication with the filter press body, so that the sludge can accurately enter the filter press. The liquid discharge pipe arranged at a position adjacent to the waste pipe on the vertical plate and in communication with the filter press body at one end and extending into the overflow pool at the other end can reasonably guide the waste liquid filtered by the filter press back to the overflow pool to participate in the further treatment process of the sewage, so that the waste liquid is recycled, and the material recycling path inside the entire sewage treatment system is optimized.

[0012] Further, the waste pipe is connected with an air supply assembly on the pipe wall near one end of the vertical plate, the air supply assembly comprises an air supply main pipe, an air supply hose and an air pump, the air pump is arranged on the ground, the air supply main pipe is arranged on the upper side of the platform and extends to the ground away from the platform to be connected with the air pump, and the air supply hose is connected between the waste pipe and the air supply main pipe.

[0013] By adopting the technical scheme, the gas enters the waste pipe through the aeration assembly and enters the filter press together with the sludge. On the one hand, the gas generates certain pressure fluctuation in the filter press, and the expansion and contraction of the gas can exert additional pressure on the sludge, so that the filtrate is more easily squeezed out of the sludge. On the other hand, during the filter pressing process, the bubbles can play the role of skeleton, so that the solid particles in the sludge are more easily aggregated and accumulated, thereby forming filter cake with a more compact structure and smaller pores. The smaller pores can prevent liquid from passing through and allow gas to escape, accelerating the solid-liquid separation process, and the well-structured filter cake can improve the efficiency of liquid filtration.

[0014] Further, the waste pipe is provided with a first flange seat on the side wall, and a second flange seat for connecting the aeration hose is mounted on the first flange seat. The aeration hose is sleeved on the second flange seat, and a first fastener for cooperating with the second flange seat is sleeved outside the aeration hose.

[0015] By adopting the technical scheme, the waste pipe is provided with a first flange seat on the side wall, and a second flange seat for connecting the aeration hose is mounted on the first flange seat. The aeration hose is sleeved on the second flange seat, and a first fastener for cooperating with the second flange seat is sleeved outside the aeration hose. Compared with simple sleeving or buckle connection, flange connection can better withstand external forces such as vibration and pulling that may occur during aeration, ensuring that the connection between the aeration hose and the waste pipe will not easily loosen or fall off. The second flange seat is sleeved on the aeration hose, and the first fastener for cooperating with the second flange seat is sleeved outside the aeration hose. The fastener tightly fixes the aeration hose on the second flange seat, so that there is almost no gap or relative displacement space between the two, ensuring that there is no leakage of gas during transmission.

[0016] Further, the first flange seat is provided with a stop valve.

[0017] By adopting the technical scheme, the first flange seat is provided with a stop valve. According to the actual sewage treatment and sludge treatment situation, the staff can flexibly adjust the gas flow into the aeration hose and then into the waste pipe. In the initial treatment stage of the sludge, a larger gas flow is needed to quickly disturb the sludge and accelerate the liquid separation. At this time, the opening of the stop valve can be appropriately adjusted. When the sludge treatment reaches a certain degree and approaches the ideal solid-liquid separation state, the opening of the stop valve can be appropriately adjusted to accurately control the gas flow, so as to achieve the best treatment effect. Through accurate control of the gas flow, the treatment needs of the sludge at different stages and in different states can be better adapted, and the entire liquid separation process can be optimized. When it is necessary to check, repair or suspend the use of the aeration assembly, the gas can be cut off by operating the stop valve to stop aeration into the waste pipe. After completing the relevant operation, the stop valve can be easily opened to restore the aeration function, improving the convenience of daily operation and the maintainability of the system.

[0018] Further, the ventilation main pipe is integrally connected with a connector for sleeving the ventilation hose on the pipe wall at the end away from the air pump, and the outside of the hose is sleeved with a second fastener for cooperating with the connector.

[0019] By adopting the above technical scheme, in normal operation, the first fastener tightly fixes the ventilation hose on the second flange seat, and the second fastener fixes the ventilation hose on the connector of the ventilation main pipe, so that the double fixing mode can effectively prevent gas leakage during ventilation. When the ventilation hose needs to be replaced, the first fastener is loosened first, and the ventilation hose can be detached from the second flange seat on the side of the waste pipe. Then the second fastener is loosened, and the ventilation hose is taken off from the connector of the ventilation main pipe. The double-end loosening mode makes the dismounting process of the ventilation hose simple and direct.

[0020] Further, the waste pipe is arranged at the center position of the stand plate, the liquid discharge pipe comprises a primary branch pipe, a secondary branch pipe and a total liquid discharge pipe which are interconnected, the number of the primary branch pipes is several, one end of each primary branch pipe is vertically arranged through the edge position of the stand plate and is communicated with the filter press body, one end of each primary branch pipe away from the filter press body is connected to the secondary branch pipe, at least two primary branch pipes are connected to each secondary branch pipe, one end of each secondary branch pipe away from the primary branch pipe is connected to the total liquid discharge pipe, and at least two secondary branch pipes are connected to each total liquid discharge pipe.

[0021] By adopting the above technical scheme, the liquid discharge pipe adopts a multi-branch structure composed of a primary branch pipe, a secondary branch pipe and a total liquid discharge pipe which are interconnected, and the number of the primary branch pipes is several and the primary branch pipes are communicated with the filter press body from the edge position of the stand plate, so as to increase the channel area of the filter liquid discharge and avoid the congestion of the filter liquid discharge from one place. The filter liquid collected by the primary branch pipes is converged to the secondary branch pipes, and then is converged to the total liquid discharge pipe, so that the filter liquid discharge is more orderly. The filter liquid at different positions is preliminarily collected and integrated through the primary branch pipes, is further concentrated at the secondary branch pipes, and is finally discharged through the total liquid discharge pipe, so as to ensure that the filter liquid can smoothly and stably leave the filter press and flow back to the subsequent treatment link such as the overflow tank, avoid the disorder and interference of the filter liquid during the discharge process, and improve the efficiency and stability of the whole liquid discharge process.

[0022] Further, a slag disc for receiving solid waste slag is arranged below the filter press body, the slag disc is fixedly connected to the dredging platform, one side of the slag disc protrudes from the dredging platform, a slag discharge port is arranged on the side of the slag disc protruding from the dredging platform, and the width direction of the slag disc gradually narrows from the middle position to the side of the slag discharge port.

[0023] By adopting the technical scheme, the residue tray is arranged below the filter press body, can accurately receive the solid waste residue generated after the filter press processes the sludge, avoids the waste residue from being scattered randomly, ensures the neatness of the working area, and facilitates subsequent centralized treatment of the waste residue. The width direction of the residue tray gradually narrows from the middle position to one side of the residue discharge port, so that the waste residue can be guided by the shape of the residue tray after falling into the residue tray and gradually gathered to one side of the residue discharge port. The residue tray protrudes from the dredging platform on one side and is provided with a residue discharge port on the protruding side. When it is necessary to clean the waste residue in the residue tray, a corresponding transfer container can be placed below the residue discharge port, and the waste residue can directly fall into the transfer container along the residue discharge port, thereby achieving the transfer of the waste residue from the residue tray conveniently and quickly.

[0024] Further, the residue tray is fixedly connected with a guide pipe below the residue tray, one end of the guide pipe is located at the position of the residue discharge port, and the other end of the guide pipe away from the residue tray is inclined to the side away from the sedimentation tank.

The first fastener 3621 and the second fastener 3622 in the embodiment are preferably clamps, so as to facilitate replacement of the hose.

[0058] The implementation principle of the sewage dredging integrated system in the embodiment is as follows: the sewage in the storage tank 1 enters the overflow pool 2 through the pipeline, different levels of overflow pools 2 are formed in the overflow pool 2 by setting different partitions, and the sewage is treated step by step. In each level of the overflow pool 2, different reagents are added to remove harmful substances in the sewage. These reagents are pumped into the corresponding overflow pool 2 from the reagent barrel 5 by the lifting pump 54.

[0059] The NaOH and carbon powder in the first reagent barrel 51 are used to decompose oil substances in the first-level overflow pool 21; the sodium hypochlorite solution in the second reagent barrel 52 is used for nitrification of ammonia nitrogen in the second-level overflow pool 22; and the polyaluminum chloride and polyacrylamide (flocculants) in the third reagent barrel 53 are used to make impurities in the third-level overflow pool 23 coagulate. The stirring device 25 can mix the reagents and the sewage sufficiently, thereby improving the treatment effect. The treated sewage flows into the sedimentation tank 3 through the drain elbow 241. The guide plate 31 with the inclined honeycomb channel 311 can make the flocculation material effectively settle in the settling hopper 34. The water overflow tank 32 and the toothed baffle 33 on the upper part of the sedimentation tank 3 can intercept and remove floating scum. After secondary filtration through the toothed baffle 33, the dischargeable water meeting the discharge standard enters the clean water tank 4 through the water overflow port 41 for further use or direct discharge.

[0060] The flocculation material and sludge in the sewage in the sedimentation tank 3 settle in the settling hopper 34 and are guided out to the dredging mechanism 6 through the waste pipe 35 for pressure filtration treatment. When the sludge enters the main body of the filter press 62, the air supply assembly 36 is used to accelerate the solid-liquid separation, the waste liquid return guide pipe 623 is used to guide the waste liquid to return reasonably, and the like, so that the originally complicated sludge treatment is changed into a state convenient for collection and cleaning, thereby improving the treatment efficiency of the entire sewage treatment system on the sludge. The waste liquid after pressure filtration is guided into the fourth-level overflow pool 24 through the multi-stage waste liquid guide pipe 623, and is subjected to cyclic treatment with the turbid water in the fourth-level overflow pool 24. The solid waste produced by pressure filtration falls into the residue tray 611 below the filter press 62. The operator sweeps the solid waste into the residue discharge port 6111 on the dredging platform 61, and the solid waste falls to the ground through the guide pipe 612, so that the ground operator can uniformly collect the solid waste and perform subsequent treatment.
