Centrifugal cyclic purification method for sewage

Abstract

The invention discloses a centrifugal cyclic purification method for sewage. According to the method, a bolt at a discharge outlet formed in the left side of an outer tank is unscrewed so as to allowthe bolt to withdraw from a nut; a bottom cover at the discharge outlet formed in the left side of the outer tank is pulled out; water to be filtered is injected into a water inlet; an external powersource of a first motor is turned on so as to allow a bevel gear at the shaft end of the motor to rotate; the bevel gear drives a bevel gear ring and an inner tank body connected with the bevel gear ring to rotate, so water in the cavity of the inner tank body rotates with the inner tank body and centrifugal force is generated; and sewage passes through a filter screen at an accelerated speed forfiltering, then flows out form the discharge outlet formed in the left side of the outer tank and is then collected.

Description

technical field [0001] The invention relates to the technical field of sewage purification, in particular to a centrifugal sewage circulation purification method. Background technique [0002] Sewage treatment (wastewater treatment): The process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] In order to replace the sewage treatment work, the sewage purification device has been widely used by people. For example, the invention patent with the application number CN204702593U includes a water blocking plate, a frequency conversion motor, a centrifugal hole and a water outlet. Although the structure of the invention patent is simple, However,...

Problems solved by technology

[0003] In order to replace the sewage treatment work, the sewage purification device has been widely used by people. For example, the invention patent with the application number CN204702593U includes a water blocking plate, a frequency conversion motor, a centrifugal hole and a water outlet. Although the structure of the invention patent is simple, However, after a long time of operation, the filter will accumulate waste residues, and there are no effective treatment measures, resulting in a reduction in the efficiency of sewage treatment, which cannot meet the needs of modern industries for sewage treatment devices
