Description

Technical Field

[0001] The present invention relates to the technical field of river wastewater treatment, and in particular to a wastewater treatment device for river management and a process thereof. Background Art

[0002] The generation of river wastewater mainly comes from multiple aspects, including urban domestic sewage, industrial wastewater discharge, and pollution caused by agricultural activities. Therefore, the composition of river wastewater is complex, including domestic garbage, suspended particulate matter, heavy metals and pathogens.

[0003] At present, the methods of river management are relatively simple. Usually, the upper water body of the river is managed through manual salvage and single-layer screen filtration, but the middle and lower water bodies of the river cannot be treated simultaneously, resulting in incomplete cleaning of river wastewater, which affects the water quality of the river. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a wastewater treatment device and process for river management, which can simultaneously clean the surface layer of the water body and the middle and lower layers of the water body, and at the same time use a multi-step treatment device to solve the problems existing in different waters in a targeted manner, making wastewater treatment more comprehensive and efficient.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a wastewater treatment device for river management, comprising a first treatment chamber, a second treatment chamber and a third treatment chamber arranged in sequence from top to bottom, the first treatment chamber is connected to the second treatment chamber through a fixed bracket installed on its outer side wall, a plurality of lamp racks are distributed on the bottom circumference of the second treatment chamber, and the second treatment chamber is connected to the third treatment chamber through the lamp rack;

[0006] A plurality of groups of water absorption components are circumferentially distributed on the outer side wall of the first processing chamber;

[0007] The water absorption assembly includes an angle adjuster installed on the outer side wall of the first treatment chamber, a surface water absorption pipe and an underwater suction pipe, one end of the surface water absorption pipe is connected to the angle adjuster through a rotating shaft, and the other end of the surface water absorption pipe is connected to a surface water absorption port, and the angle adjuster can control the expansion range of the surface water absorption pipe so that the surface water absorption port can absorb water close to the surface of the water body;

[0008] The surface water absorption pipe is sleeved with two fixed rings arranged at intervals, an electric slide rail is installed between the two fixed rings, and a motor for driving the electric slide rail is installed on the fixed ring near the first processing chamber. The underwater suction pipe is connected to a slider installed on the electric slide rail through a U-shaped clip. Driven by the motor, the slider moves along the extension direction of the electric slide rail, thereby adjusting the depth of the underwater suction pipe entering the water body.

[0009] The tops of the surface water suction pipe and the underwater suction pipe are both provided with a T-shaped pipe, and a hose I is provided at the outer wall of the first processing chamber, one end of the hose I extends into the first processing chamber and is connected to the water inlet installed in the first processing chamber, and the other end of the hose I is connected to the T-shaped pipe installed on the surface water suction pipe, and the water in the surface water suction pipe is transferred to the first processing chamber through the hose I through the T-shaped pipe;

[0010] A hose II is provided on the outer wall of the second treatment chamber, one end of which extends into the second treatment chamber, and the other end of which is connected to a T-type pipe installed on an underwater suction pipe, thereby transmitting the wastewater sucked underwater to the second treatment chamber.

[0011] Preferably, the first processing chamber is provided with a plurality of groups of mutually cooperating crushing rollers. Since the pollutants on the surface of the water body are relatively large in volume, the pollutants on the surface of the water body are transferred to the first processing chamber through the surface water suction pipe and are initially crushed by the crushing rollers to be converted into fine particles.

[0012] A plurality of leak holes are provided at the bottom of the first processing chamber, and the treated pollutants enter the second processing chamber through the leak holes.

[0013] Preferably, a sieve body is installed in the second processing chamber, and the sieve body is a conical structure that is narrow at the top and wide at the bottom. A plurality of sieve holes are opened on the surface of the sieve body, and a rotatable movable ball is installed on the top of the sieve body. When the pollutants processed by the first processing chamber enter the sieve body, the pollutants are scattered by the sieve body surface and the movable ball, and the particles that meet the size of the sieve holes fall into the interior of the sieve body for further processing.

[0014] Preferably, a plurality of drug dosing boxes are installed on the outer wall of the second treatment chamber, and flocculants, disinfectants and heavy metal capture agents are respectively added into the drug dosing boxes, so that the suspended particles, pathogens and heavy metals in the surface water falling from the first treatment chamber and the middle and lower water bodies drawn by the underwater drawing pipe can be reacted for a long time in the second treatment chamber using chemical reagents.

[0015] Preferably, a plurality of precision screens are installed at the bottom of the second processing chamber for filtering the treated suspended particles, and a control valve is provided at the position of the precision screens for controlling the water output from the second processing chamber.

[0016] Preferably, an upwardly inclined gas rod is installed at the position of the water absorption component on the outer wall of the second processing chamber, and the telescopic end of the gas rod is connected to the surface water absorption pipe. The gas rod can cooperate with the angle adjuster to adjust the position of the surface water absorption pipe and can also play a role in supporting the surface water absorption pipe.

[0017] Preferably, the diameter of the third treatment chamber is larger than that of the first treatment chamber and the second treatment chamber, and the height of the third treatment chamber is smaller than that of the first treatment chamber and the second treatment chamber. An ultraviolet irradiation lamp is installed on the side of the lamp holder facing the inside of the third treatment chamber. The large diameter and low height setting can better spread the water body, and the ultraviolet irradiation lamp can fully cover the treated water body, so that the sterilization effect is more significant;

[0018] The third treatment chamber is provided with a plurality of water outlet valves distributed around its circumference, through which the treated water is discharged again to improve the water quality of the surrounding water.

[0019] Preferably, a float is installed at the bottom of the third processing chamber. Since the bottom diameter of the third processing chamber is relatively large, the buoyancy of the device can be increased by installing a float at the bottom thereof, so that the device can float stably on the water surface.

[0020] Preferably, the diameter of the surface water suction pipe is larger than that of the underwater suction pipe, so as to absorb larger pollutants. At the same time, the outer part of the surface water suction pipe is provided with a foam tube, which can increase the buoyancy of the surface water suction pipe. A suspension detector is installed at the bottom of the underwater suction pipe to detect the surrounding water quality and move to a suitable position through an electric slide rail to absorb river wastewater.

[0021] A wastewater treatment process for river management, which is applicable to the above-mentioned wastewater treatment device for river management, and the process steps are as follows:

[0022] S1: The device is placed in the river channel, and the air rod cooperates with the angle adjuster to unfold the water absorption component, wherein the surface water absorption pipe floats on the surface of the water body and relies on the surface water absorption port to absorb the surface wastewater mixed with pollutants into the first processing chamber, and the crushing rollers in the first processing chamber cooperate with each other to finely crush the large volume of pollutants, and the crushed particles enter the second processing chamber through the leakage hole at the bottom of the first processing chamber;

[0023] S2: The suspended liquid detector detects the water body that exceeds the pollution index, and the motor drives the electric slide rail to drive the underwater suction pipe connected to the slider to move to the position of the water body to be treated. Since the underwater suction pipe has a certain length and can extend to the middle and lower layers of the water body, the river wastewater in the middle and lower layers is sucked into the second treatment chamber;

[0024] S3: The surface water that has been crushed and the middle and lower water that has been sucked through the underwater suction pipe enter the second treatment chamber and impact with the movable ball, so that the water is dispersed on the screen body. At the same time, the flocculants, disinfectants and heavy metal capture agents contained in multiple dosing boxes are added to the second treatment chamber according to the proportion. Since the water is dispersed, the chemical agents can better contact and react with the impurities in the water, and the formed sediment is screened by the precision screen at the bottom of the second treatment chamber;

[0025] S4: The control valve sets a preset threshold value according to the amount of water entering the second treatment chamber, and controls the outflow, so that the chemical agent in the second treatment chamber can fully react with the wastewater and continuously treat the wastewater, and the water after screening by the precision screen is controlled by the control valve to flow into the third treatment chamber;

[0026] S5: The third treatment chamber adopts a large diameter and low height setting to better spread the water body and allow the ultraviolet lamp to fully cover the treated water body. The water body treated by the ultraviolet lamp can effectively kill pathogens and ensure the health of the water quality. The outlet valve sets the water outlet interval time to discharge the treated water body, thereby completing the entire river wastewater treatment step.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. In the present invention, the air rod cooperates with the angle adjuster to unfold the water absorption component, which can simultaneously clean the surface layer of the water body and the middle and lower layers of the water body. The surface water absorption pipe floats on the surface of the water body and relies on the surface water absorption port to suck the surface wastewater of the water body mixed with pollutants into the first treatment chamber, and pre-treats it and cooperates with the underwater suction pipe to suck the river wastewater in the middle and lower layers into the second treatment chamber, so as to solve the problems existing in different waters in a targeted manner, making the wastewater treatment more comprehensive and efficient.

[0029] 2. In the present invention, the surface water that has been crushed and the middle and lower water that is sucked through the underwater suction pipe collide with the movable ball when entering the second processing chamber, and the water is dispersed on the sieve body. Since the sieve body has a conical structure that is narrow at the top and wide at the bottom, the water can be dispersed and can better contact and react with the chemical agent.

[0030] 3. The third treatment chamber of the present invention adopts a large diameter and low height setting to better spread the water body and allow the ultraviolet irradiation lamp to fully cover the treated water body. The water body treated by the ultraviolet irradiation lamp can effectively kill pathogens and ensure the health of the water quality. BRIEF DESCRIPTION OF THE DRAWINGS

Since the underwater suction pipe 63 has a certain length and can extend into the middle and lower layers of the water body, the river wastewater in the middle and lower layers is sucked into the second treatment chamber 2;

[0059] S3: The surface water that has been crushed and the middle and lower water that has been sucked through the underwater suction pipe 63 enter the second processing chamber 2 and impact with the movable ball 9, so that the water is dispersed on the screen body 8.
