Integrated sewage harmless equipment

Abstract

The invention provides integrated sewage harmless equipment, and belongs to the technical field of sewage and sludge treatment. The equipment comprises a flow meter, a valve, an ultrasonic/ultraviolet reaction tank, a flow guide partition plate, an ultraviolet lamp UVC, an overflow water outlet pipe, an emptying port I, an overflow water tank, a secondary treatment water inlet control valve, an ultrasonic/photocatalytic reaction tank, a flow guide partition plate loaded with a photocatalyst, a flow guide partition plate slot, a photocatalytic light source UVA, a water outlet, an emptying port II and an ultrasonic transducer. Under the combined action of ultrasonic waves, ultraviolet rays and photocatalytic reaction, multiple purposes of inactivation of pathogenic microorganisms in sewage, degradation of antibiotics and resistant genes of the antibiotics and the like are achieved, and harmless treatment of the sewage is achieved. The technology can greatly reduce the risk of by-products caused by chemical agent disinfection, is simple to operate, does not need auxiliary equipment and facilities, is safe and efficient, and is especially suitable for harmless treatment of secondary effluent of a sewage treatment plant, biogas slurry and sewage with similar properties.

Description

technical field [0001] The invention relates to the technical field of sewage and sludge treatment, in particular to an integrated sewage harmless equipment. Background technique [0002] Sewage also contains a large number of pathogenic microorganisms and micro-pollutants. If it is directly discharged, it will pollute the soil, surface and groundwater, and threaten human health. The harmlessness of sewage is an important link and key unit to ensure the health of the water environment. In recent years, due to the extensive use and abuse of antibiotics, unmetabolized antibiotics are discharged with feces and enter the environment. The aerobic and anaerobic treatment processes of sewage have a certain removal effect on antibiotics, but they are not enough to eliminate antibiotic pollution. Environmental health risks. In addition, bacterial antibiotic resistance caused by antibiotics, that is, antibiotic resistance genes, is one of the new pollutants that has attracted much at...

Problems solved by technology

As a representative disinfectant, chlorine has a stable disinfection effect and low cost, but its broad-spectrum disinfection is weak, such as poor inactivation of Cryptosporidium and Giardia, and the disinfection process will also produce "three causes" disinfection by-products, some Chlorine disinfection has been canceled in countries and regions
