Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically to a device for controlling odors in soil and groundwater. Background Technology

[0002] Soil and groundwater contaminated by sewage often have an unpleasant odor. Organic matter such as proteins and sugars in sewage undergo anaerobic decomposition in soil or groundwater, producing foul-smelling gases such as hydrogen sulfide and ammonia. Heavy metals (such as lead and cadmium) or high concentrations of salts in industrial wastewater dissolve and release odors through soil pores. To fundamentally solve the odor problem, source control and strict treatment of industrial wastewater are necessary. Current technologies typically employ wastewater treatment equipment for this purpose.

[0003] Application number CN202220374743.5 describes an environmentally friendly wastewater deodorization device. Wastewater and a deodorizing agent are introduced into a primary deodorization container via a fixed connection to the side wall of the primary deodorization container. A dynamic deodorization component within the primary deodorization container performs initial deodorization of the wastewater. Subsequently, the wastewater treated by the dynamic deodorization component is vaporized by a gasification component. The vaporized wastewater is then transferred to the secondary deodorization container via a gas transfer component located between the primary and secondary deodorization containers. A secondary deodorization is achieved through a filtration component, effectively improving the wastewater deodorization effect and thus achieving environmental protection goals during the later stages of wastewater discharge. However, this design has shortcomings. It cannot pre-treat wastewater, which often contains large particulate impurities that easily clog the device, affecting its operating efficiency and treatment effect.

[0004] Therefore, we propose a soil and groundwater odor control device. Utility Model Content

[0005] The main purpose of this utility model is to provide a soil and groundwater odor control device. Through the design of the pretreatment box, the device can pretreat sewage, and impurities in the sewage can be effectively removed, thereby improving the operating efficiency and treatment effect of the entire odor control device; it can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A soil and groundwater odor control device includes a positioning base, a primary deodorizing container, an installation base, and a pretreatment box. The primary deodorizing container is fixedly installed at one end of the upper surface of the positioning base. A water inlet pipe is provided at the upper part of one end of the primary deodorizing container. An installation base for installing the pretreatment box is connected to the end of the positioning base near the water inlet pipe. Limiting plates are vertically connected to both sides of the installation base near the end of the positioning base. The limiting plates are fixedly connected to the positioning base and the two sides of the primary deodorizing container respectively by first bolts. An operating box for supporting a delivery pump is provided at the lower part of the pretreatment box near the end of the primary deodorizing container. The supporting delivery pump is connected to the pretreatment box through a water pumping pipe. The end of the water inlet pipe away from the primary deodorizing container is connected to the supporting delivery pump. The pretreatment box is vertically equipped with a first partition and a second partition, which divide the interior of the pretreatment box into multiple relatively independent chambers. From left to right, the multiple chambers are a first filtration chamber, a second filtration chamber, and a sedimentation chamber. A sealing cover is fastened to the top of the pretreatment box at the location of the first and second filtration chambers. A feed hopper is fixedly connected to the upper part of the pretreatment box away from the water inlet pipe. A first filter screen and a second filter screen are installed at an angle in the first filtration chamber, with the first filter screen located directly above the second filter screen. A slot for installing a collection box is provided at the lower part of the pretreatment box away from the supporting conveying pump.

[0007] By adopting the above technical solution, the design of the first and second slots facilitates the installation and removal of the first and second filter screens within the first filter chamber. The first filter screen is positioned directly above the second filter screen, and its mesh diameter is larger than that of the second filter screen. Through the cooperation of the first and second filter screens, graded filtration of wastewater can be achieved. Because the first and second filter screens are inclined within the first filter chamber, impurities intercepted by the first and second filter screens can easily slide down the inclined surface of the filter screens as wastewater passes through, effectively preventing the accumulation of impurities on the first and second filter screens; thus improving the filtration efficiency of the first and second filter screens.

[0008] Specifically, the first partition and the second partition are arranged in parallel relative to each other, the second filter chamber is located between the first partition and the second partition, the top of the second partition is fitted with a baffle, and the bottom of the second partition is vertically connected to the inner wall of the bottom of the pretreatment box.

[0009] Specifically, the inner walls on both sides of the pretreatment box are provided with sliding grooves for installing baffles directly above the second partition, and both ends of the baffles are slidably connected to the inner walls on both sides of the pretreatment box.

[0010] Specifically, both ends of the first partition are vertically connected to the upper part of the inner walls on both sides of the pretreatment box, and the collection box is located below the first partition. The collection box is connected to the first filter chamber and the second filter chamber respectively.

[0011] Specifically, the pretreatment box has a first slot for installing the first filter screen and the second filter screen on the inner wall of the end near the feed hopper, and the first partition has a second slot for installing the first filter screen and the second filter screen on the inner wall of the side near the feed hopper.

[0012] Specifically, the first slot and the second slot are staggered, the first filter screen is located above the second filter screen, and the first filter screen and the second filter screen are inclined downward on the side away from the first partition.

[0013] The beneficial effects of this utility model are: (1) The soil and groundwater odor control device of this utility model, through the design of the pretreatment box, enables the device to pretreat sewage, and the impurities in the sewage can be effectively removed, thereby improving the operating efficiency and treatment effect of the entire odor control device; through the design of the first slot and the second slot, it is convenient to install and remove the first filter screen and the second filter screen in the first filter chamber, and the first filter screen is located directly above the second filter screen. The mesh diameter of the first filter screen is larger than that of the second filter screen. Through the cooperation of the first filter screen and the second filter screen, the sewage can be filtered in stages; since the first filter screen and the second filter screen are inclined in the first filter chamber, when the sewage passes through, the impurities intercepted by the first filter screen and the second filter screen can easily slide down along the inclined surface of the filter screen, effectively avoiding the accumulation of impurities on the first filter screen and the second filter screen; thereby improving the filtration efficiency of the first filter screen and the second filter screen. (2) The soil and groundwater odor control device of the present invention has a collection box located below the first partition and connected to the first filter chamber and the second filter chamber. When sewage passes through the gap at the bottom of the first partition and enters the second filter chamber, the fine suspended matter in it will naturally settle into the collection box under the action of gravity. It makes full use of the principle of gravity sedimentation, and can effectively collect suspended impurities without the need for additional power equipment, thereby further improving the practicality of the device.

[0017] As one embodiment of this utility model, such as Figures 1-3 As shown, the soil and groundwater odor control device of this utility model includes a positioning base 1, a primary deodorizing container 2, a mounting base 3, and a pretreatment box 5. The primary deodorizing container 2 is fixedly installed at one end of the upper surface of the positioning base 1. A water inlet pipe 24 is provided at the upper part of one end of the primary deodorizing container 2. The mounting base 3 for installing the pretreatment box 5 is connected to the end of the positioning base 1 near the water inlet pipe 24.

The lower part of the pretreatment box 5 near the end of the primary deodorizing container 2 is provided with an operating box for supporting a delivery pump 23. The supporting delivery pump 23 is connected to the pretreatment box 5 through a water pumping pipe 18. The end of the water inlet pipe 24 away from the primary deodorizing container 2 is connected to the supporting delivery pump 23. The pretreatment box 5 is vertically installed with a first partition 6 and a second partition 7, which divide the interior of the pretreatment box 5 into multiple relatively independent chambers. The multiple chambers are, from left to right, a first filtration chamber 9, a second filtration chamber 10, and a sedimentation chamber 11. A sealing cover 22 is fastened to the top of the pretreatment box 5 at the location of the first filtration chamber 9 and the second filtration chamber 10. A feed hopper 21 is fixedly snapped onto the upper part of the pretreatment box 5 at the end away from the water inlet pipe 24. A first filter screen 13 and a second filter screen 14 are installed at an angle in the first filtration chamber 9, with the first filter screen 13 located directly above the second filter screen 14. A slot 20 for installing a collection box 12 is provided at the lower part of the pretreatment box 5 at the end away from the supporting conveying pump 23.

[0018] In use, the soil leachate or groundwater to be treated is injected into the pretreatment tank 5 through the feed hopper 21. The wastewater first enters the first filter chamber 9 and is filtered out by the first filter screen 13 to remove larger impurities. After being filtered by the first filter screen 13, the wastewater continues to flow down to the second filter screen 14, which further filters out smaller impurities. After two stages of filtration, the wastewater passes through the gap at the bottom of the first partition 6 and enters the second filter chamber 10. The fine suspended solids remaining in the wastewater settle into the collection box 12 under gravity and are collected uniformly. The wastewater passes over the baffle 8 at the top of the second partition 7 and enters the sedimentation chamber 11. The wastewater is further settled in the sedimentation chamber 11. The conveying pump 23 draws the clarified wastewater from the upper layer of the sedimentation chamber 11 into the conveying pump 23 through the water pump pipe 18. After being pressurized by the conveying pump 23, it is conveyed to the first-stage deodorization container 2 through the water inlet pipe 24.

[0019] The present invention also includes that the first partition 6 and the second partition 7 are arranged in parallel relative to each other, the second filter chamber 10 is located between the first partition 6 and the second partition 7, the top of the second partition 7 is snapped with a baffle 8, and the bottom of the second partition 7 is vertically connected to the inner wall of the bottom of the pretreatment box 5.

[0020] The present invention also includes that the inner walls on both sides of the pretreatment box 5 are provided with sliding grooves 17 for installing baffles 8 directly above the second partition 7, and both ends of the baffles 8 are slidably connected to the inner walls on both sides of the pretreatment box 5.

[0021] The present invention also includes that both ends of the first partition 6 are vertically connected to the upper part of the inner walls on both sides of the pretreatment box 5, the collection box 12 is located below the first partition 6, and the collection box 12 is connected to the first filter chamber 9 and the second filter chamber 10 respectively.

[0024] When using this utility model, the first filter screen 13 and the second filter screen 14 need to be installed at an angle into the first filter chamber 9. Since the first slot 15 and the second slot 16 are staggered, it is necessary to ensure that the first filter screen 13 is directly above the second filter screen 14, and that the side of both that is away from the first partition 6 is tilted downward so that impurities can slide down the inclined surface. Then, the soil leachate or groundwater to be treated is injected into the pretreatment tank 5 through the feed hopper 21. The sewage first enters the first filter chamber 9 and is filtered out by the first filter screen 13 to remove larger impurities. After being filtered by the first filter screen 13, the sewage continues to flow down to the second filter screen 14 to further remove smaller impurities. After two stages of filtration, the sewage passes through the gap at the bottom of the first partition 6 and enters the second filter chamber 10. The fine suspended solids remaining in the sewage settle into the collection box 12 under the action of gravity and are collected uniformly. The sewage passes over the baffle 8 at the top of the second partition 7 and enters the sedimentation chamber 11. The sewage is further settled in the sedimentation chamber 11. The conveying pump 23 draws the clarified sewage from the upper layer of the sedimentation chamber 11 into the conveying pump 23 through the water pump pipe 18. After being pressurized by the conveying pump 23, it is transported to the first-stage deodorization container 2 through the water inlet pipe 24.
