Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, and more specifically to a medicine mixing device for a sewage treatment system. Background Art
[0002] Industrial wastewater is of various types and has complex water quality. The wastewater contains refractory organic matter. The refractory organic pollutants are generally pretreated by Fenton oxidation, high-tech oxidation and other technologies. The above oxidation technologies usually use the strong oxidizing property of oxidizing agents to achieve chain breaking treatment of refractory organic matter. If the agent and water cannot be fully mixed and contacted during the wastewater treatment process, the refractory organic matter in the wastewater cannot be completely degraded, which not only increases the processing load of the subsequent treatment unit, but also wastes the agent and increases the operating cost of the sewage treatment plant.
[0003] At present, the reagent mixing is mainly done by mixing it evenly in a dosing barrel with a mixer and then pumping it to the oxidation device. The barreled dosing mixing device not only increases the cost but also increases the floor space of the wastewater treatment system. The mixer needs more mixing time to mix the reagents. If the time is not enough, it will lead to uneven mixing of the reagents, which not only increases the processing load of the subsequent treatment units, but also wastes the reagents and increases the operating cost of the sewage treatment plant.
[0004] Therefore, it is an urgent problem to be solved by technical personnel in this field to provide a sewage treatment system reagent mixing device that can mix reagents evenly, occupies a small area, and can add multiple reagents at the same time. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a sewage treatment system reagent mixing device which has high reagent mixing efficiency, small footprint, and can add multiple reagents at the same time.
[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions, which mainly include:
[0007] A sewage treatment system reagent mixing device comprises a mixing box, a perforated aeration pipe, a corrugated joint, an air pipe, a fan, a water inlet pipe, a dosing pipe and a water outlet pipe, wherein a perforated aeration pipe is installed inside the mixing box, the perforated aeration pipe runs through the mixing box body and is connected to the air pipe through a corrugated joint, the other side of the air pipe is connected to the fan, the other side of the mixing box is connected to the water inlet pipe through a corrugated joint, the water inlet pipe is connected to a plurality of dosing pipes, and the bottom of the mixing box is connected to the water outlet pipe through a corrugated joint.
[0008] Preferably, a water inlet pump is installed on the water inlet pipe.
[0009] Preferably, a dosing pump is installed on the dosing pipe.
[0010] Preferably, a stop valve is installed on the water outlet pipe.
[0011] Preferably, a regulating valve is installed on the air pipe.
[0012] It can be seen from the above technical solution that, compared with the prior art, the utility model adopts a perforated aeration stirring method to ensure uniform mixing of the reagent and the wastewater, maximize the utilization rate of the reagent, and reduce the operating cost of the wastewater treatment plant; the reagent mixing device is designed on the water inlet pipeline to reduce the floor space of the wastewater treatment station, thereby reducing the overall investment cost. Multiple reagents can be added at the same time according to actual needs, solving the problems of uneven reagent mixing, waste of reagents, and increased operating costs of sewage treatment plants.
