It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0032] Please refer to the following for details. Figure 1-2 The coagulation sedimentation and fully automatic filter water purifier consists of a coagulation sedimentation tank and a biological filter tank, both made of carbon steel. The coagulation sedimentation tank and biological filter tank are stacked, with the coagulation sedimentation tank located below the biological filter tank. They can be fixed together by welding or screws. This stacked arrangement reduces the footprint and operating costs.

[0033] Specifically, the coagulation sedimentation tank is equipped with three first partitions 101, which divide the inner cavity of the coagulation sedimentation tank into four parts: a lifting tank 102, a mixing tank 103, a flocculation tank 104, and a sedimentation tank 105. The bottom of the lifting tank 102 is equipped with a water inlet pipe 106. The lifting tank 102 and the mixing tank 103 are connected by a first lifting pump 3. The mixing tank 103 is connected to the flocculation tank 104, and the flocculation tank 104 is connected to the sedimentation tank 105. The first partitions 101 between the mixing tank 103 and the flocculation tank 104, and between the flocculation tank 104 and the sedimentation tank 105 are provided with through holes. The mixing tank 103 and the flocculation tank 104, and the flocculation tank 104 and the sedimentation tank 105 are connected through the through holes in the first partitions 101.

[0034] The mixing tank 103 and the flocculation tank 104 are respectively provided with a first feeding port 107 and a second feeding port 108. Coagulants and flocculants can be added through the first feeding port 107 and the second feeding port 108 respectively. The coagulants and flocculants are commonly used agents in the prior art, which are used to carry out coagulation and flocculation reactions on sewage to produce flaky or flocculent precipitates.

[0035] The mixing tank 103 is equipped with a first stirring device 109, and the flocculation tank 104 is equipped with a second stirring device 110. Both the first stirring device 109 and the second stirring device 110 include a motor, a stirring shaft, and a stirring paddle. The motor drives the stirring shaft to rotate, and the stirring paddle is fixed to the stirring shaft and rotates together with the stirring shaft. The water in the tank is stirred to allow the drug and water to fully mix. The first stirring device 109 and the second stirring device 110 are used to stir and mix the drugs and accelerate the reaction.

[0036] The top of the sedimentation tank 105 is provided with multiple inclined tubes 111 with the same inclination direction and angle and arranged at equal intervals. On the one hand, the flocculent sediment settles to the bottom of the sedimentation tank 105 by its own weight. On the other hand, the flocculent sediment is intercepted by the inclined tubes 111 and then sinks down to the bottom of the sedimentation tank 105 by its own weight along the inclined surface formed by the multiple inclined tubes 111.

[0037] A sludge pump 5 is installed at the bottom of the sedimentation tank 105. The sludge pump 5 is used to transport sludge in the sedimentation tank 105 to prevent excessive sludge deposition and facilitate the periodic discharge of sludge.

[0038] Inclined plates 112 are installed on both sides of the sedimentation tank 105, which serve as guides.

[0039] Specifically, the biological filter tank is equipped with two second partitions 201, which divide the internal cavity of the coagulation sedimentation tank into three parts: an aerobic biological filter 202, an anoxic biological filter 203, and a water purification tank 204. The aerobic biological filter 202 is connected to the anoxic biological filter 203, and the anoxic biological filter 203 is connected to the water purification tank 204. The bottom of the water purification tank 204 is equipped with an outlet pipe 205. The partitions between the aerobic biological filter 202 and the anoxic biological filter 203, and between the anoxic biological filter 203 and the water purification tank 204 are also provided with through holes. The aerobic biological filter 202 and the anoxic biological filter 203, and between the anoxic biological filter 203 and the water purification tank 204 are connected through the through holes on the second partitions 201. An interception net is provided at the through holes on the second partitions 201, which can intercept the filter media in the aerobic biological filter 202 and the anoxic biological filter 203.

[0040] The aerobic biological filter 202 contains spherical lightweight porous biological filter media, and the anoxic biological filter 203 contains nitrifying biological filter media. The spherical lightweight porous biological filter media and the nitrifying biological filter media are common filter media in existing technologies, which can effectively remove harmful substances such as ammonia nitrogen, nitrate nitrogen, and total nitrogen from wastewater.

[0041] The sedimentation tank 105 and the aerobic biological filter 202 are connected by a second lift pump 4.

[0042] This utility model relates to a coagulation sedimentation and fully automatic top-and-bottom filter water purifier, the working principle of which is explained in conjunction with the accompanying drawings:

[0043] First, the wastewater enters the lifting tank 102 through the inlet pipe 106. The wastewater in the lifting tank 102 is transported to the mixing tank 103 by the first lifting pump 3. Coagulants and flocculants are added to the mixing tank 103 and the flocculation tank 104. The first stirring device 109 and the second stirring device 110 are started to fully mix the drugs and water and accelerate the reaction. The resulting sediment will settle at the bottom of the sedimentation tank 105 and can be discharged periodically by the sludge pump 5. The clear liquid on the upper layer of the sedimentation tank 105 enters the aerobic biological filter 202 and the anoxic biological filter 203 through the second lifting pump 4 for biological aerobic oxidation treatment and denitrification treatment, respectively. Finally, the purified water flows out from the outlet pipe 205 of the purification tank 204.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
