Description

Technical Field

[0001] The present invention relates to the technical field of water body treatment, and in particular to a device for treating black and odorous water bodies. Background Art

[0002] Black and odorous water is a serious water pollution phenomenon. It occurs when the aquatic environment is exposed to organic pollution that exceeds its self-purification capacity. The aerobic decomposition of organic matter causes the oxygen consumption rate in the water to exceed the reoxygenation rate, resulting in water hypoxia. This leads to incomplete and slowed degradation of organic matter. The anaerobic biodegradation process generates odorous substances such as hydrogen sulfide, ammonia, and mercaptans, as well as black substances, which cause the water to become black and odorous.

[0003] At present, the treatment of black and odorous water bodies mainly focuses on several aspects: intercepting pollution and controlling sources; chemical treatment technology, including enhanced flocculation, algaecide, activated carbon, etc.; ecological treatment technology, which is to rebuild and restore the water ecosystem by creating an environment suitable for the survival and reproduction of various organisms, mainly including microbial remediation method, aquatic plant remediation method, aquatic animal remediation method, etc.

[0004] At present, the treatment measures for black and odorous water bodies mainly include: pumping black and odorous water bodies in the natural environment to sewage treatment plants for treatment. This method has a good treatment effect, but the sewage extraction cost is high, the energy consumption is large, and the operating cost is relatively high; or aeration is carried out in the black and odorous water bodies in the natural environment to increase the dissolved oxygen content, and at the same time, corresponding chemical agents are sprayed into the black and odorous water bodies in the natural environment for black and odorous water body treatment, and aquatic plants are planted in the black and odorous water bodies in the natural environment. If this method is to achieve a real treatment effect, it requires a large amount of water and a wide area, and aeration, chemical spraying and ecological treatment must be carried out at the same time. In reality, on the one hand, aeration operations, spraying of corresponding chemicals, and ecological treatment operations are not synchronized, but are carried out separately, which results in limited treatment effects of the existing method, long treatment time, and repeated treatment effects; on the other hand, aeration operations, spraying of corresponding chemicals, and ecological treatment operations must be carried out in the entire black and odorous water area to achieve effective black and odorous water treatment effects. Therefore, the aeration operations, spraying of corresponding chemicals, and ecological treatment operations for black and odorous water bodies must be moved regularly, and moving the aeration devices and ecological treatment devices and stopping them in a certain area to complete the black and odorous water treatment requires manual intervention, which is time-consuming and labor-intensive; finally, the aeration operations, spraying of corresponding chemicals, and ecological treatment operations in conventional black and odorous water treatment cannot take into account municipal aesthetics. In the long-term treatment of black and odorous water bodies, people are still reluctant to approach. Summary of the Invention

[0057] The interior of the outer channel cylinder 10 is divided into an outer upper channel cylinder and an outer lower channel cylinder by a partition 18 , and the interior of the inner channel cylinder 11 is divided into an inner upper channel cylinder and an inner lower channel cylinder by a partition 18 .

[0059] All channel holes 19 are embedded with fixed sponge blocks to facilitate the flocculant layer 14 and the deodorant layer 15 to slowly enter the outer channel cylinder 10 from the outer reagent cylinder 8 and enter the inner channel cylinder 11 from the inner reagent cylinder 9, and then flow into the black and odorous water body through the orifice plate, thereby maintaining the long-term treatment effect of the black and odorous water body treatment device.

[0060] A treatment base plate 16 is provided at the inner end of the inner reagent cylinder 9 of each treatment device.

[0061] The aeration pipes include a main aeration pipe 20 and three branch aeration pipes 21; the main aeration pipe 20 is installed on the aeration pipe bracket and is equipped with a fan; an aeration branch pipe 21 is fixedly installed in the middle of each layer of the treatment base plate 16, and each aeration branch pipe 21 is provided with an aeration hole; the main aeration pipe 20 is fixedly connected to the aeration branch pipe 21 at the top; the aeration branch pipe 21 of each layer of treatment equipment is sleeved outside the aeration branch pipe 21 of the treatment equipment on the upper layer; bolts 22 are inserted through the mutually penetrating aeration holes of the two mutually sleeved aeration branch pipes 21, and one end of the bolt 22 extending from the aeration branch pipe 21 is threadedly connected to a nut 23.

[0062] The upper end of the treatment bottom plate 16 of each treatment device is provided with a plurality of microorganism carrier rods 24. The lower end of the treatment bottom plate 16 of each treatment device is provided with a floating block 2 to ensure that each treatment device has a certain buoyancy, and the gravity of each treatment device is greater than the buoyancy.

[0064] A method for treating a black and odorous water body comprises the following steps:

[0065] S1: The black and odorous water treatment device is placed in the black and odorous water body. The operator controls the grid plate moving power device 3 to move and turn the black and odorous water treatment device to the black and odorous water body area that needs to be treated. The sinking block 27 is pressed into the bottom mud of the black and odorous water body;

[0066] S2: The fan starts working, and the air is transmitted to the black and odorous water body through the aeration pipe. Each layer of treatment equipment performs the corresponding treatment process;

[0067] S3: When the area of black and odorous water that needs to be treated is small and the water layer is shallow, a separate black and odorous water treatment device can be used to perform S1 and S2 operations;

[0068] When the area of black and odorous water that needs to be treated in the water body is large and the water layer is deep, the operator moves several black and odorous water treatment devices to the black and odorous water area that needs to be treated, and then ties several black and odorous water treatment devices together, and the sinking blocks 27 of each black and odorous water treatment device are inserted into the bottom mud; the height of the multi-layer treatment equipment and the lower-layer treatment equipment is adjustable, the nuts 23 and bolts 22 are removed, the aeration branch pipe 21 and the treatment equipment connected to the aeration branch pipe 21 are adjusted downward to a suitable position, and then bolts 22 are inserted into the corresponding aeration holes on the mutually connected aeration branch pipes 21, and the protruding ends of the bolts 22 are tightened with nuts 23 to achieve the height adjustment of the multi-layer treatment equipment. When the operator leaves, the multiple black and odorous water treatment devices automatically carry out the treatment process of the black and odorous water body;

[0069] S4: The flocculant layer 14, deodorant layer 15, solid material adsorption layer, organic soil layer 17 and biodegradable rods of a single or several black and odorous water treatment devices tied together can be replaced, added or cleaned to ensure the long-term good treatment effect of the black and odorous water treatment device.

[0070] The working principle of the present invention is:

[0071] The black and odorous water treatment device is placed in the black and odorous water body. The operator sits on the grid plate 1. Due to the buoyancy of the floating block 2, the upper end surface of the grid plate 1 is above the water surface of the black and odorous water body. The operator controls the grid plate moving power device 3 to make the black and odorous water treatment device move and turn.

[0072] When the device reaches a heavily polluted black and odorous water area, the grid plate moving power device 3 stops working, and the operator uses a tool to press the sinking block 27 into the bottom mud of the black and odorous water body to fix the position of the device; the fan starts working;

[0073] Driven by the fan, the air is transmitted to the aeration pipe and then transmitted to the black and odorous water through the aeration holes, thereby increasing the dissolved oxygen content in the water, solving the imbalance problem of oxygen supply and consumption in the black and odorous water, and effectively reducing the black and odorous water.

[0074] Each layer of the multi-layer treatment equipment in this solution is a small complete treatment system, and each layer of the treatment equipment is equipped with an aeration device, a flocculation device, a deodorization device, an adsorption filler device, a soil aquatic plant device (including an emergent plant layer 25 and a submerged plant layer 26), and a microbial carrier device;

[0075] In each layer of treatment equipment: the solid material adsorption layer uses large gaps in the filter media, which can further treat black and odorous water bodies; activated carbon has good physical adsorption, is simple to use, has fast results, and can effectively deodorize black and odorous water bodies; and the ceramsite filter media has a strong adsorption effect, which is conducive to the inoculation and growth of microorganisms, maintaining a large biomass; the zeolite ceramsite combination filter media not only has a strong adsorption effect, but also has a better ammonia nitrogen removal effect than a single ceramsite filler. Several solid material adsorption layers will not cause secondary pollution of the water body.

[0076] Flocculants and deodorizers continuously and slowly carry out chemical treatment of black and odorous water bodies, thereby removing heavy metal ions and malodorous substances in the black and odorous water bodies;

[0077] The upper layer of emergent plants, such as safflower, moneywort, or canna, can not only absorb excess nitrogen, phosphorus, and potassium in the water, repairing and purifying the water quality, but also have the effect of beautifying the city landscape; the middle layer of submerged plants 26, such as dwarf water grass or red thread grass, can also remove excess nitrogen, phosphorus and other pollutants in the water, thereby repairing and purifying the water quality; the bottom layer of submerged plants 26, such as black algae, can further remove excess nitrogen, phosphorus and other pollutants in the water.

[0078] The upper layer of emergent plants, the middle layer of submerged plants, and the lower layer of submerged plants are arranged in a stepped pattern, without overlapping in width. This creates a visually appealing appearance, allowing people to approach even during the long-term treatment of black and odorous water bodies. The combination of emergent plants and submerged plants in treating black and odorous water bodies is more effective in absorbing pollutants such as nitrogen and phosphorus, and can better repair and purify water quality.

[0079] The biodegradable rods provide a carrier for the growth of microorganisms; the presence of photosynthesis by emergent and submerged plants provides a favorable environment for the growth of microorganisms, achieving the purpose of regulating the balance of microorganisms in the water body and removing nitrogen and phosphorus;

[0080] In each layer of treatment equipment, aeration operation, chemical treatment operation, and ecological treatment operation (including microbial remediation and aquatic plant remediation) are carried out simultaneously and automatically. Therefore, the treatment of black and odorous water bodies can achieve the advantages of effective treatment effect and shortened treatment time.

[0081] When multiple layers of treatment equipment are set up in the through trough 4, a height difference is formed in the black and odorous water body, so that each layer of treatment equipment can effectively treat the black and odorous water body at the corresponding height, covering the treatment operations close to the water surface area, shallow water area, and deep water area;

[0082] When the area of black and odorous water that needs to be treated in the water body is small and the water layer is shallow, the operator moves the black and odorous water treatment device to the black and odorous water area that needs to be treated, and then inserts the sinking block 27 into the bottom mud. The operator can leave and the black and odorous water treatment device automatically performs the treatment process of the black and odorous water body;

[0083] When the black and odorous water area that needs to be treated is large and the water layer is deep, the operator moves several black and odorous water treatment devices to the black and odorous water area that needs to be treated, and then ties several black and odorous water treatment devices together, such as Figure 8 As shown, the sinking block 27 of each black and odorous water treatment device is inserted into the bottom mud, and the operator can leave, allowing the black and odorous water treatment device to automatically perform the black and odorous water treatment process; at the same time, the height of the middle-level treatment equipment and the lower-level treatment equipment is adjustable. The nuts 23 and bolts 22 are removed, the aeration branch pipe 21 is adjusted downward to a suitable position, and the treatment equipment connected to the aeration branch pipe 21 is also lowered to a suitable position. Then, bolts 22 are inserted into the corresponding aeration holes on the mutually connected aeration branch pipes 21, and the protruding ends of the bolts 22 are tightened with nuts 23. This can achieve the height adjustment of the middle-level treatment equipment and the lower-level treatment equipment (both can be completed with the help of tools);

[0084] When several black and odorous water treatment devices are tied together, the grid movable inner plate 103 is disassembled, such as Figure 8 As shown, in order to avoid blocking the sunlight needed by the upper emergent plants, middle submerged plants and lower submerged plants arranged in a stepped manner, the upper emergent plants, middle submerged plants and lower submerged plants can grow better, be more beautiful and achieve better treatment effects on black and odorous water bodies;

[0085] In each layer of the treatment equipment of this black and odorous water body treatment device, the flocculant layer 14, the deodorant layer 15, the solid material adsorption layer, the organic soil layer 17, and the biodegradable rod can all be replaced, added, or cleaned to ensure the long-term, continuous, and good treatment effect of the black and odorous water body treatment device.

[0086] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
