Description

Technical Field

[0001] The present invention relates to the technical field of drainage systems, and in particular to an integrated catering oily wastewater collection device and a setting method thereof. Background Art

[0002] In order to improve and enhance the quality of urban water environment, various cities have successively implemented a large number of water-related infrastructure projects in the areas of black and odorous water treatment, sponge cities, water environment management, and renovation of drainage systems in old urban areas. Although the above-mentioned water-related infrastructure projects have continuously improved the quality of the water environment and achieved certain results, there are still some areas where sewage is directly discharged, especially in areas with densely populated restaurants in old urban areas and where shops along the street dump oily wastewater into rainwater outlets, so water environment management is still in the stage of moving forward under heavy burdens.

[0003] At present, the pretreatment of oily wastewater generated by catering businesses is mainly carried out by installing a grease trap indoors or an outdoor grease trap, connecting the end of the grease trap or grease trap to the sewage system, and then collecting catering oily wastewater at the rainwater outlet. The engineering measures for collecting catering oily wastewater at the rainwater outlet include: setting an interception well at the end of the rainwater pipe to intercept the oily wastewater into the sewage system to ensure that the sewage does not flow into the river on sunny days; transforming the rainwater outlet into a new type of rainwater outlet with an interception effect, intercepting the sewage into the sewage system on sunny days, and overflowing into the rainwater system on rainy days; setting up a single-function sewage dumping pool to connect to the sewage system. In addition to engineering measures, management measures are also taken to reduce the entry of oily wastewater into the rainwater system and standardize the way catering businesses discharge oily wastewater.

[0004] Existing engineering measures cannot fundamentally solve the problem of dumping oily wastewater and have many shortcomings. The interception method is prone to backflow due to the high water level of the sewage pipe network, and the failure to timely operate and maintain the rainwater facilities will lead to interception failure, which will cause a large amount of oily wastewater to enter the rainwater system. Since the single dumping pool has no oil-proof water seal function, it will cause problems such as odor return and pipe clogging. At the same time, the law enforcement and supervision of relevant departments have increased the difficulty, and it is difficult to achieve the expected effect with a large amount of cost. In view of the above problems, it is urgent to provide a collection device that can be used for oily wastewater in the catering industry. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an integrated catering oil wastewater collection device and a setting method thereof.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of the relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0030] like Figure 1-7As shown, an embodiment of an integrated catering oily wastewater collection device includes a first chamber 100 for dumping oily wastewater, a second chamber 200 for blocking oil and dirt, and a third chamber 300 for water sealing, wherein the first chamber 100, the second chamber 200 and the third chamber 300 are sequentially arranged below the ground; a pouring port 110 for dumping oily wastewater is provided at the top of the first chamber 100, and a filtering device 120 is provided at the pouring port 110; the first chamber 100 is fixedly connected to the second chamber 200, and the first chamber 100 is connected to the second chamber 200 through a first water pipe 140; the second chamber 200 is connected to the bottom of the third chamber 300; the third chamber 300 is connected to the municipal sewage system through a second water pipe 310, and the water inlet of the second water pipe 310 extends into the water of the third chamber 300; the water outlet of the second water pipe 310 is lower than the water inlet of the first water pipe 140.

[0031] When in use, the catering business pours the catering oily wastewater from the pouring port 110, and the oily wastewater is filtered by the filter device 120 and enters the first chamber 100. Among them, there are fine solids that are not filtered by the filter device in the oily wastewater, and the fine solids in the oily wastewater are precipitated to the bottom of the first chamber 100. The oily wastewater in the first chamber 100 enters the second chamber 200 through the first water pipe 140, and the oily wastewater is separated into oil and water layers in the second chamber 200. Since the density of oil is lower than that of water, the oil layer is constrained by the second chamber 200, reducing the oil layer from entering the third chamber 300. The wastewater in the second chamber 200 flows from the bottom of the second chamber 200 into the third chamber 300. It should be noted that the outlet of the second water pipe 310 is lower than the inlet of the first water pipe 140, and a water level difference can be formed between the two, so that the wastewater in the third chamber 100 can be smoothly discharged into the municipal sewage system.

[0032] Furthermore, if Figure 2 As shown, the filter device 120 includes a first filter portion 121 and a second filter portion 122 . The first filter portion 121 is engaged at the pouring port 110 , and the second filter portion 122 is disposed below the first filter portion 121 . The filter aperture of the first filter portion 121 is larger than that of the second filter portion 122 .

[0033] Specifically, the first filter 121 can be a grate with a grid structure on it. The material can be stainless steel or plastic products, which can intercept large debris to prevent people from throwing garbage into the first chamber. The second filter 122 can be a sewage interception hanging basket, and the sewage interception hanging basket is hung in the first chamber 100. At the same time, the sewage interception hanging basket is located below the grate, wherein the filter aperture of the sewage interception hanging basket is smaller than the filter aperture of the grate to prevent blockage at the dumping port 110. When the intercepted solid debris is full, open the first cover plate 130, remove the grate, and lift the sewage interception hanging basket for cleaning.

[0034] like Figure 6 As shown, a first cover plate 130 is provided on the top of the pouring port 110. The first cover plate 130 covers the pouring port 110, is hinged to the first chamber 100, and is above the ground. The top surface of the first cover plate 130 is marked with a logo of "Oil Wastewater Dumping Port" for easy identification and maintenance.

[0035] Specifically, a hinge 150 is provided on one side of the first chamber 100, and the first cover 130 is connected to the first chamber 100 through the hinge 150, so that the first cover 130 can be opened to one side to prevent the odor in the first chamber 100 from spreading and have an anti-theft function. At the same time, the first cover 130 is higher than the ground to prevent surface runoff or rainwater from entering the pouring port 110.

[0036] Furthermore, if Figure 4 As shown, a slot 210 is provided between the second chamber 200 and the third chamber 300 , and a partition 220 is provided in the slot 210 . The bottom of the partition 220 is higher than the bottom plates of the second chamber 200 and the third chamber 300 to form a space for sewage to flow.

[0037] Specifically, the partition 220 can block the oily wastewater after the oil-water separation in the first chamber 100, and the sewage without oily wastewater in the lower layer of the first chamber 100 enters the third chamber 300 through the lower space of the partition 220, thereby realizing the collection of the wastewater containing oily wastewater. It should be noted that when the oily wastewater is poured into the first chamber 100 for the first time, part of the oily wastewater will flow from the second chamber 200 through the bottom of the partition 220 into the third chamber 300, thereby causing part of the oily wastewater to flow into the municipal sewage system. In order to reduce the flow of oily wastewater into the municipal sewage system, water is injected into the second chamber 200 and the third chamber 300 before the first oily wastewater is poured, so that the height of the water exceeds the bottom of the partition 220. When the oily wastewater flows from the first chamber 100 into the second chamber 200, the oily wastewater can achieve oil-water stratification in the second chamber 200 to reduce the amount of oily wastewater flowing from the bottom of the partition 230 into the third chamber 300, thereby reducing the amount of oily wastewater discharged into the municipal sewage system.

[0038] Furthermore, if Figure 2 As shown, a removable second cover plate 230 is provided on the top of the second chamber 200 and the third chamber 300 to prevent rainwater from entering and facilitate maintenance. The second cover plate 230 is flush with the ground to reduce the impact of the top of the second chamber 200 and the third chamber 300 on pedestrians. The second cover plate 230 can be a solid glass fiber reinforced plastic cover plate. When the second chamber 200 and the third chamber 300 are blocked, the second chamber 200 and the third chamber 300 can be cleaned by opening the solid glass fiber reinforced plastic cover plate.

[0039] Furthermore, if Figure 2As shown, the water inlet of the first water pipe 140 is higher than the bottom plate of the first chamber 100, so that a sedimentation space for fine solid impurities in the oily wastewater is formed at the bottom of the first chamber 100, thereby reducing the fine solid impurities in the oily wastewater from entering the first chamber 100 and causing siltation.

[0040] Furthermore, if Figure 2 As shown, the first water pipe 140 includes a first short tube 141, a detachable first elbow 142 and a second short tube 143. The first short tube 141 is arranged at the water inlet of the first chamber 100; one end of the first elbow 142 is connected to the first short tube 141, and the other end of the first elbow 142 is connected to the second short tube 143, and the second short tube 143 extends below the water surface in the second chamber 200.

[0041] Specifically, the oily wastewater in the first chamber 100 enters through the first short tube 141, and enters the second chamber 200 through the first elbow 142 and the second short tube 143. When blockage occurs between the first short tube 141, the first elbow 142 and the second short tube 143, the first elbow 142 and the second short tube 143 can be disassembled and cleared.

[0042] Furthermore, if Figure 2 As shown, the second water pipe 310 includes a third short pipe 311, a detachable second elbow 312 and a fourth short pipe 313. The third short pipe 311 is arranged at the drain outlet of the third chamber 300, and the third short pipe 311 is connected to the municipal sewage system; one end of the second elbow 312 is connected to the third short pipe 311, and the other end of the second elbow 312 is connected to the fourth short pipe 313, and the fourth short pipe 313 extends below the water surface in the third chamber 300; the third short pipe 311 is lower than the first short pipe 141.

[0043] Specifically, the wastewater in the second chamber 200 enters the third chamber 300 from the space below the partition 220. Since the height of the third short pipe 311 is lower than the height of the first short pipe 141 to form a water level difference, the wastewater in the third chamber 300 can smoothly flow into the municipal sewage system through the fourth short pipe 313, the second elbow 312 and the third short pipe 311. It should be noted that since one end of the fourth short pipe 313 is located below the water surface of the wastewater in the third chamber 300, it acts as a water seal, which can effectively prevent the odor in the municipal sewage pipe from flowing back.

[0044] A method for setting up the above-mentioned integrated catering oily wastewater collection device specifically comprises the following steps:

[0045] The first chamber 100, the second chamber 200 and the third chamber 300 are arranged below the ground in sequence, and the pouring port 110 is arranged on the sidewalk in front of the catering business, which can reduce the impact of the device on the business operation and pedestrians, and facilitate the dumping of oily wastewater from catering businesses. The height of the first cover plate 130 from the ground is set to be not less than 50 mm, in order to prevent surface runoff and rainwater from entering during rainfall. The distance from the pouring port 110 to the road curb is not less than 0.4m, and the tops of the second chamber 200 and the third chamber 300 are both flush with the ground. The top of the pouring port 110 is hinged with the first cover plate 130, and the opening direction of the first cover plate 130 is set to open upward facing the sidewalk, which is convenient for manual operation.

[0046] The dumping port 110 is set in the middle of adjacent catering shops, and the number of the dumping ports 110 does not exceed 3, so as to meet the needs of adjacent catering shops to dump oily wastewater at the same time and avoid the catering shops directly pouring the oily wastewater into the nearby rainwater inlet for convenience because the distance is too long.

[0047] Specifically, when there is only one catering store with sewage dumping demand, the dumping port 110 can be set in front of the store. When there are two adjacent catering stores with sewage dumping demand at the same time, the dumping port 110 can be set in the middle of the two adjacent stores.

[0048] In summary, the present invention can intercept solid debris, separate oil and water, and prevent the backflow of odor from the municipal sewage system; the present invention can achieve simple construction, short construction period, small footprint and easy maintenance during construction, can effectively reduce the water environment pollution caused by oily wastewater entering the rainwater system, and can reduce the supervision tasks of relevant law enforcement and regulatory departments.

[0049] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
