Sewage purification treatment device for water treatment engineering

Abstract

The invention discloses a sewage purification treatment device for water treatment engineering. The invention relates to the technical field of sewage treatment devices. The device specifically comprises a filtering tank and a sterilizing tank assembly, and the top of the filtering tank is connected with a feeding mechanism; an activated carbon fiberboard is distributed in the filtering tank; a quartz sand plate is arranged on one side of the activated carbon fiber plate, fixing bolts penetrate through the periphery of the activated carbon fiber plate and the periphery of the quartz sand plate, a tank cover is connected to one end of the filtering tank, sealing bolts penetrate through the periphery of the tank cover, a water delivery pump is connected to the bottom of the filtering tank, and the sterilization tank assembly is connected to one end of the water delivery pump. According to the sewage purification treatment device for water treatment engineering, a flow dividing pipe is atransparent glass pipe and is spirally distributed on the periphery of a center column, filtered sewage is divided into the flow dividing pipe to be irradiated by ultraviolet rays of an ultraviolet sterilization lamp, and thus the sterilization effect is achieved; the arrangement is beneficial for improving the ultraviolet transmittance, comprehensively irradiating water in the flow dividing pipe,improving the sterilization effect and shortening the time needed by sterilization.

Description

technical field [0001] The invention relates to the technical field of sewage treatment devices, in particular to a sewage purification treatment device for water treatment engineering. Background technique [0002] Sewage purification treatment device is an indispensable and important equipment in water treatment engineering. Sewage purification is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. It is widely used in construction, agriculture, transportation, Various fields such as energy, petrochemicals, environmental protection, urban landscape, medical care, and catering are increasingly entering the daily lives of ordinary people. [0003] The existing sewage purification treatment device needs to firstly separate the sewage from the impurities contained in it. However, the sewage purification treatment device cannot discharge the solid impurities in time, which will easily lead to pipeline b...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a sewage purification treatment device for water treatment engineering, which solves the problem that the sewage purification treatment device proposed in the above background technology needs to firstly separate the sewage from the impurities contained therein. However, the sewage The purification treatment device cannot discharge solid impurities in time, which may easily lead to blockage of the pipeline, and for the sewage purification treatment device using ultraviolet sterilization, the time required for sterilization is long due to the depth of the water body, which is not conducive to improving the efficiency of sewage purification
