Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment tower and a sewage treatment method thereof. Background Art

[0002] The process of treating sewage in a sewage treatment tower is a complex and systematic process, mainly based on the principles of physics, chemistry and biology, and aims to remove harmful substances in sewage or convert them into harmless substances to meet discharge standards or reuse requirements.

[0003] There is a biological trickling filter in the prior art. The body of the biological trickling filter is filled with crushed stones or other artificial filter materials. The sewage is sprinkled from the top of the biological trickling filter through a water distribution device. When passing through the biological trickling filter, the filter material intercepts the suspended matter in the sewage.

[0004] The above technology has the following disadvantages: the water distribution pipe cannot rotate during the sewage distribution process, resulting in the sewage dripping on the artificial filter material in a fixed position, causing excessive impurities to accumulate in this part of the artificial filter material, and other parts have no filtering effect. At the same time, the artificial filter materials are hung on the rack and fall due to gravity. When installing them in the tower, the artificial filter materials will shake and get entangled, resulting in subsequent time-consuming and labor-intensive sorting. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the shortcomings of the prior art, the present invention provides a sewage treatment tower and a sewage treatment method thereof, which have the advantages of controlling the rotation of the distribution pipe so that the wastewater drips on the filter material and is evenly distributed, and fixing the installed filter material to prevent it from shaking and entanglement, thereby solving the above-mentioned problems.

[0007] (II) Technical solution

[0008] In order to achieve the purpose of controlling the rotation of the distribution pipe so that the wastewater drips onto the filter material and is evenly distributed, and fixing the installed filter material to prevent it from shaking and entanglement, the present invention provides the following technical scheme: a sewage treatment tower, comprising a tower body, the top and bottom of the tower body are detachably mounted with tower covers by bolts, a water inlet pipe and an exhaust pipe are fixedly mounted on the top of the tower cover at the upper end, a return pipe and a drain pipe are fixedly mounted on the bottom of the tower cover at the lower end, one end of the water inlet pipe and the return pipe are connected with a three-way solenoid valve through a pipeline, a circulating pump is fixedly connected between the return pipe and the three-way solenoid valve, a box body is movably mounted on the bottom of the water inlet pipe through a sealing seat, a distribution pipe is fixedly connected to the outside of the box body, a tail sealing cap is fixedly mounted on the tail end of the distribution pipe, and nozzles arranged at equal intervals are fixedly connected to the bottom of the distribution pipe.

[0010] Preferably, a limiting protrusion is fixedly installed below the inner wall of the tower body, and an interception component is arranged inside the tower body through the limiting protrusion.

[0011] Preferably, the interception assembly includes an upper ring plate and a lower ring plate, a sliding rod is fixedly installed on the bottom of the upper ring plate, the bottom of the sliding rod is slidably inserted into the interior of the lower ring plate, and a threaded ring is embedded at the center of the upper ring plate and the lower ring plate, and the internal thread of the threaded ring is connected to a bidirectional threaded rod.

[0012] Preferably, threaded columns are threadedly connected on the opposite surfaces of the upper ring plate and the lower ring plate, a hanging ring is fixedly installed on the other end of the threaded column, and a connecting rod is inserted into the interior of the hanging ring.

[0013] Preferably, a rope body is fixedly installed between the upper and lower connecting rods, and a biological carrier is fixedly installed on the outside of the rope body. The biological carrier is arranged in a spiral ascending shape and is made of fiber braids, fiber ropes, non-woven fabrics, towel strips or felt strips.

[0014] A sewage treatment method comprises the following steps:

[0015] S1: Sewage enters from a through hole of the three-way solenoid valve and enters the interior of the tower through the water inlet pipe. Sewage will be sprayed onto the biological carrier from the bottom nozzles of multiple distribution pipes;

[0016] S2: When sewage flows through the biological carrier, the biological carrier will absorb and metabolize the organic matter in the wastewater. These microorganisms convert organic pollutants into harmless substances through their own metabolic activities;

[0017] S3: Finally, the wastewater is collected at the bottom of the treatment tower. If the wastewater treatment is unqualified, the wastewater is pumped up through the circulation pump and sprayed from the bottom nozzle of the distribution pipe to the biological carrier for adsorption treatment again;

[0018] S4: If the wastewater is treated to be qualified, it will be discharged from the drain pipe to the next treatment process outside.

[0042] Working Principle: A sewage treatment method comprising the following steps:

[0043] S1: Sewage enters from a through hole of the three-way solenoid valve 7 and enters the interior of the tower body 1 through the water inlet pipe 3. The sewage is sprayed onto the biological carrier 1910 from the bottom nozzles 13 of the multiple distribution pipes 11;

[0044] S2: When sewage flows through the biological carrier 1910, the biological carrier 1910 will absorb and metabolize the organic matter in the wastewater. These microorganisms convert organic pollutants into harmless substances through their own metabolic activities;

[0045] S3: Finally, the wastewater is collected at the bottom of the treatment tower. If the wastewater treatment is unqualified, the wastewater is pumped up by the circulation pump 8, and the wastewater is sprayed from the bottom nozzle 13 of the distribution pipe 11 to the bio-carrier 1910 for adsorption treatment;

[0046] S4: If the wastewater is qualified after treatment, it will be discharged from the drain pipe 6 to the next treatment process outside.

[0047] The servo motor 16 drives the driving gear 17 to rotate, and the driving gear 17 engages with the tooth groove 15 on the inner wall of the extension tube 14, so that the extension tube 14 will also rotate, and then the box body 10, the distribution pipe 11 and the nozzle 13 will rotate synchronously. The rotating distribution pipe 11 and the nozzle 13 can allow the sewage to drip evenly onto the biological carrier 1910, so that the sewage is no longer concentrated in one place of the biological carrier 1910, thereby expanding the use area of ​​the biological carrier 1910 and also expanding the interception and adsorption treatment efficiency.
