Virus wastewater treatment process

Abstract

The invention provides a virus wastewater treatment process, and relates to the field of virus separation. The wastewater treatment process comprises the following steps: aiming at excrement and otherhigh solid waste flows, a solid-liquid separator is adopted to carry out dry-wet separation on living source pollution discharge. On one hand, the solid-liquid separator adopts screw separation compression, on the other hand, the sewage concentration can be effectively reduced, and on the other hand, the sewage treatment efficiency is improved. On the other hand, the concentrate is pressed into blocks which can be directly sterilized. The high-toxicity wastewater (medical and domestic wastewater) is treated by adopting a pollution-resistant secondary membrane process, so that the method is convenient and has less pollution. The invention has the technical effects and advantages that: 1, wastes generated in the treatment process can be properly treated; 2, fully-sealed forced solid-liquidseparation is adopted in the treatment process, and vent holes and produced liquid are sterilized; 3, the original polluted flow is reduced, and pollutants are not newly added;.

Description

technical field [0001] The invention relates to the field of virus separation, and specifically refers to a virus wastewater treatment process. Background technique [0002] Pneumonia caused by the new coronavirus has received great attention since its occurrence. There are patients with latent infection and asymptomatic infection in the pneumonia of new coronavirus infection. Patients with no or only mild symptoms are easy to miss diagnosis. In the face of this highly contagious virus, isolation is the best way to prevent it. But at the same time, the solid and liquid waste (high solid flow and highly toxic wastewater such as feces) generated in the isolation area has become the key to treatment. Sewage from living sources (feces, urine and poisoned wastewater) in highly active disease areas is extremely harmful. Conventional water treatment methods have a long process, occupy a large area, have a large amount of concentrated products and low concentrations, and consume a ...

Problems solved by technology

Sewage from living sources (feces, urine and poisoned wastewater) in highly active disease areas is extremely harmful. Conventional water treatment methods have a long process, occupy a large area, have a large amount of concentrated products and low concentrations, and consume a large amount of chemicals. There are viruses in the treatment process. risk of leakage

However, the defects of existing biochemical technologies such as MBR and MBBR: long time, many process products, and many terminal wastes

Severity: (1) For unknown toxic sources, such as chlorine-resistant and oxidation-resistant toxic sources, only ultrafiltration-disinfecting is discharged, and there is a risk of secondary pollution

(2) Adding activated sludge increases the stock of toxic sources
