Centrifugal sedimentation type water purification method for large-size sewage treatment plant

Abstract

The invention discloses a centrifugal sedimentation type water purification method for a large-size sewage treatment plant. The centrifugal sedimentation type water purification method adopts a tank body, a water inlet is formed in the top end of the outer wall of the tank body; a vent hole is formed in the top end of the outer wall of the tank body; the inner wall of the vent hole is connected with the outer wall of the tank body; a bracket is mounted on the inner wall of the tank body; the outer wall of the bracket is connected with the inner wall of the tank body; a clean water hole is formed above the bracket. By adopting the centrifugal sedimentation type water purification method for the large-size sewage treatment plant, with the combination of the tank body, a first filtering net and a second filtering net, under the action of a backflow hole, good support adjustment is provided for connection of a motor with a valve body by the tank body, sewage can be sufficiently stirred andfiltered, the sewage purification efficiency can be improved, furthermore a cleaning hole is prevented from being blocked by concentrated sludge or sediment, the purchase cost of a user can be reduced, resource waste of the centrifugal sedimentation type water purification method for the large-size sewage treatment plant can be avoided, and the method is applicable to popularization and application.

Description

technical field [0001] The invention relates to the technical field of industrial water purifiers, in particular to a centrifugal sedimentation water purification method for large sewage treatment plants. Background technique [0002] The industrial water purification device is composed of three parts: a pretreatment system, a fine treatment system, and a post-treatment system.

[0002] The industrial water purification device is composed of three parts: a pretreatment system, a fine treatment system, and a post-treatment system. Particulate matter), colloid, organic matter, hardness, microorganisms and other impurities are greatly reduced, and the processing load of the fine treatment system such as electrostatic desalination can be used to extend its service life. It is widely used in coal-containing wastewater, ash and slag washing wastewater, Industrial comprehensive sewage, chemical workshop wastewater, mine wastewater, hydraulic coal mining wastewater, coal washing wastewater, coking wastewater in the coal industry, beneficiation wastewater, smelting wastewater, circulating cooling water, oily wastewater in the metallurgical industry, production wastewater in ceramics, abrasives, and foundry industries , recycled papermaking wastewater, printing and dyeing wastewater, electroplating wastewater, high turbidity river water, wet dedusting water and domestic drinking water with rivers, lakes and wells as water sources. The existing sewage purifiers are high in cost and slow in purification speed, which seriously hinders The treatment of sewage has caused many enterprises to discharge a large amount of sewage. In the prior art, for example, the invention patent with application number 96243048.X includes a cylindrical main body with a conical bottom at the lower end and a concentrated mud There is a filter net layer on the upper part of the main cylinder, and the filter material is filled on the filter net layer. There is a baffle plate on the filter material, and there are multiple filter heads on the baffle plate. The water pipe interface is characterized in that there is a down-spin isolation tube at the lower part of the main cylinder, the down-spin isolation tube is cylindrical, the upper end of the down-spin isolation tube is a bell mouth, and the upper edge of the bell mouth is sealed and connected with the inner wall of the main tube, and the sewage The water inlet pipe enters the main cylinder below the connection between the downspin isolation cylinder and the main body cylinder. Although the invention has a simple structure, there are many deficiencies and defects. In the existing equipment, the design of the downspin isolation cylinder has defects. Lack of sewage cleaning and discharge devices, impurities in the mud can easily cause the blockage of the concentrated mud drain, and manual work is required to remove the blockage, which increases the workload of the operator, makes the operator prone to physical fatigue, and reduces the operator's work Efficiency increases the production and processing cost of the enterprise and causes waste of resources of the water purifier. In view of these situations, in order to avoid the above-mentioned technical problems, it is necessary to provide a method to overcome the defects in the prior art.
