[0025] Please see Figures 1 to 5 ,

[0026] The utility model provides a sewage treatment device for water resources used in a breeding farm. In the prior art, the treatment cost of sewage from a breeding farm is high and the efficiency is low. In order to solve the above technical problems, the utility model optimizes the sewage treatment equipment to improve the sewage purification efficiency, and can be reused at a low cost.

[0027] The invention comprises a filter tank 100, an aeration tank 200 and a purification tank 300 which are connected in sequence. The structure in the filter tank 100 is described in detail first. As shown in the figure, the filter tank 100 is in a cube shape. A grid separation seat 110 is arranged in the filter tank 100. The grid separation seat 110 comprises a seat plate 111. A grid plate 112 is arranged around the seat plate 111. An annular tooth groove 113 is arranged in the seat plate 111. A separation cylinder 120 is arranged above the seat plate 111. An annular tooth ring 121 is arranged at the bottom of the separation cylinder 120. The annular gear ring 121 can move within the base plate 111, and the annular gear ring 121 can be inserted into the annular gear groove 113. Specifically, inner teeth are arranged within the annular gear groove 113, and outer teeth are arranged outside the annular gear ring 121. When the separation cylinder 120 is inserted into the annular gear groove 113, the inner teeth and the outer teeth are offset and matched with each other, which is not shown in the figure. In order to enable the separation cylinder 120 to be stably installed on the seat plate 111, an outer ring can also be arranged on the outer wall of the separation cylinder, and the seat plate and the annular gear groove 113 are sleeved therein.

[0028] In addition, an installation box 140 is provided at the bottom of the base plate 111, and a driving motor is provided in the installation box 140. In addition, a placement groove 114 is concavely provided at the bottom of the annular tooth groove 113, and a driving tooth is provided in the placement groove 114. A driving wheel is provided at the end of the output shaft of the driving motor, and the driving wheel can engage with the driving tooth to drive the annular tooth groove 113 to rotate, thereby driving the separation cylinder 120 provided above the annular tooth groove 113 to rotate.

[0029] In order to facilitate the rapid fusion reaction of sewage and medicine in the separation cylinder 120, a plurality of separation holes are set on the cylinder wall of the separation cylinder 120, so an inner cylinder 122 is further set in the separation cylinder 120, and the function of the inner cylinder 122 is to prevent the sewage from flowing out. Specifically, a vertical slide groove 123 is set on the inner wall of the separation cylinder 120, and a vertical slider 124 matching the vertical slide groove 123 is set on the outer wall of the inner cylinder 122. The inner cylinder 122 is inserted into the inner wall of the separation cylinder 120 so that it blocks the separation holes. Under the action of the driving motor, the separation cylinder 120 will rotate, thereby mixing the liquid medicine and the sewage. The liquid medicine can be a flocculant, etc. After being fully mixed with the liquid medicine, the inner cylinder 122 is removed, so that the treated liquid medicine flows out of the separation cylinder 120 and flows to the grid plate 112. Through the two-layer filtration of the separation cylinder 120 and the grid plate 112, large impurities can stay on the grid plate 112 or the inner wall of the separation cylinder 120, and some fine impurities settle into mud and accumulate in the sludge separation component 130 below.

[0030] The sludge separation assembly 130 includes a sludge receiving bin body 131, and an insert body 132 is extended outwardly on both sides of the sludge receiving bin body 131. In addition, a pull-out plate 133 is also provided on one side wall of the sludge receiving bin body 131. As shown in the figure, the side wall of the pull-out plate 133 extends above the outer wall of the filter tank 100, so that the sewage contained in the filter tank 100 will not overflow. In addition, in order to avoid water overflow and the like, a water stop strip can be provided between the side wall of the pull-out plate 133 and the filter tank 100. The pull-out plate 133 is mainly provided to facilitate pulling out the sludge receiving bin body 131 to dump the sludge.

[0031] First, the aeration tank 200 is described in detail:

[0032] The treated sewage in the filter tank 100 flows into the aeration tank 200 through the water pipe. A mounting frame 240 is installed in the aeration tank 200. A plurality of aeration rings 210 are arranged on the mounting frame 240. The aeration rings 210 are installed from top to bottom, and a plurality of aeration holes are arranged in the aeration rings 210. A clamping body 250 is arranged on the mounting frame 240. The clamping body 250 can be a conventional clamp or the like. The clamping body 250 faces the aeration ring 210 and is used to clamp the aeration ring 210. In addition, the clamping body 250 clamps the gas delivery pipe so that the gas is delivered to each aeration ring 210. In addition, a stirring group is arranged in the aeration ring 210, and the stirring group includes a stirring shaft 220 and The stirring blade 230 arranged outside the stirring shaft 220 is used to further add a purification liquid into the aeration tank 200, which may be an oxidant or a disinfectant, etc. The liquid can be purchased directly online and will not be elaborated on here. After the further reaction and impurity removal process, the purified sewage is transferred to the purification tank 300 for purification. Certain liquid can also be added to the purification tank 300, which can be selectively added according to the water quality test. For example, a decolorizing agent, a microbial additive, etc. can be added. After the purified water is transferred to the subsequent procedure, it can be directly discharged when it meets the discharge requirements. If it does not meet the discharge requirements, it will be further purified until it meets the requirements.

[0033] As shown in the figure, the filter tank 100, the aeration tank 200 and the purification tank 300 are installed in a stepped manner. The installation height of the filter tank 100 is higher than that of the aeration tank 200, and the installation height of the aeration tank 200 is higher than that of the purification tank 300. This arrangement is conducive to sewage transfer.

[0034] The workflow of this utility model is as follows:

[0035] The sewage in the farm is pumped into the separation cylinder 120 with the inner cylinder 122, and liquid medicine is added into the separation cylinder 120. The separation cylinder 120 is rotated under the drive of the driving motor, so as to drive the sewage and the liquid medicine to fully fuse. After a certain reaction time, the inner cylinder 122 is taken out from the separation cylinder 120, and the sewage flows out of the separation cylinder 120. Some larger impurities will remain in the separation cylinder 120 and flow to the grid plate 112, which will intercept some impurities again and partially precipitate in the separation cylinder 120 and the sludge separation component 130. The sludge will accumulate in the sludge receiving bin 131, and the upper sewage will flow into the aeration tank 200 through the pipe body. The sludge remaining in the sludge receiving bin 131 will settle and be transferred out through the pull-out plate 133.

[0036] When the sewage enters the aeration tank 200, liquid medicine is added thereto, and oxygen is transported to the aeration ring 210 through the aeration pipe. Under the action of the stirring group, the sewage and the liquid medicine are further stirred to fully blend. The continuous aeration can make the reaction more complete and increase the efficiency of purifying the sewage. When the reaction is completed, it is transferred to the purification tank 300 for purification again until the discharge requirements are met.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
