Description
Technical Field
The invention relates to a sewage treatment device, in particular to an integrated sewage treatment device.
Background
Since 2020, new crown diseases have saddled the world. The methods of human-to-human contact, respiratory droplets, aerosols, and contact with contaminated organisms are well known as well-known viral transmission pathways. However, as the epidemic situation is continuously worsened in some countries, the targeted virus gene fragments have been detected in wastewater, sewage, sludge and surface river water all over the world recently, which also causes the worry of people about new coronavirus entering the water circulation system, and also puts more urgent requirements on disinfection and sterilization for the discharge of sewage and wastewater in the areas where the current viruses are mainly spread and controlled.
The disinfection is an important guarantee for killing pathogenic microorganisms and reducing the risk of water-borne disease transmission in the water treatment process. To date, although research on new coronaviruses in water and wastewater is still limited, the new coronaviruses are respiratory viruses with an envelope, which are more easily inactivated by disinfectants, than non-enveloped viruses (such as adenovirus, rotavirus, norovirus, and the like). Therefore, a sewage treatment emergency device suitable for sterilization can be researched around the basic mode of virus inactivation (such as high temperature, illumination, pH value change, disinfectant and the like), bacterial infection and virus can be inhibited, emergency treatment and disposal of sewage and wastewater can be realized, and the safety of a discharged water body can be ensured.
Sewage discharge from buildings is generally divided into two forms: one is directly discharged without treatment, collected by a sewage pipeline and then converged into a town sewage treatment plant for unified treatment; the other is that the sewage is specially treated and then discharged into a municipal sewage pipeline. In the first form, the work of the conventional urban sewage treatment plant focuses on the removal of organic matter and nitrogen and phosphorus removal, and the control requirement for the total number of bacteria or viruses is generally performed through a single sewage disinfection link. At present, ultraviolet disinfection accounts for 75% of the sewage treatment industry in China, namely ultraviolet rays are utilized to irradiate water bodies and destroy the molecular structures of microorganisms and other substances in the water bodies, so that the aim of inhibiting the propagation and survival of the microorganisms is fulfilled. However, in the inspection of the sewage treatment effect, the problem that the disinfection of the sewage does not reach the standard or does not reach the standard in part of time is found by adopting ultraviolet disinfection, and the non-standard rate is higher. The reason is that when suspended particles exist in the treated sewage, the suspended particles can absorb or disperse ultraviolet rays to a certain extent; in addition, microorganisms in the water can avoid ultraviolet energy if hidden near the suspended particles, so that the structure of the microorganisms is prevented from being damaged by ultraviolet rays, and the ideal treatment effect on viruses, bacteria and other harmful substances in the water cannot be achieved. The core of ultraviolet sewage disinfection is to provide enough ultraviolet dosage, and design problems, equipment defects and ultraviolet lamp quality problems are main reasons causing insufficient ultraviolet dosage. This results in some sewage treatment plants changing to chlorine disinfection instead of ultraviolet disinfection, however, this increases the chlorine pollution of the water, and because chlorine disinfection cannot kill chlorine-resistant microorganisms, there is still a potential risk in epidemic prevention.
In the second form, the specialized treatments used in public and key units to control epidemics have been disinfected with chlorine-containing disinfectants (such as chlorine dioxide and sodium hypochlorite). Because most terminal sewage treatment plants adopt a biological treatment process, if excessive residual chlorine exists in sewage, the activity of activated sludge of the terminal sewage treatment plants can be reduced or inhibited, and the normal operation of a biological treatment unit is influenced. Even if the blindness of adding disinfectant is excessive at the sewage source (particularly medical institutions and public areas) through reasonable regulation and control, the problems that disinfection byproducts are increased, soluble and nonbiodegradable organic matters are formed, the stable standard reaching of effluent COD (chemical oxygen demand) is influenced and the ecological safety of a water body is accepted are also needed to be followed. Therefore, how to conveniently, efficiently and safely treat the high-risk pathogenic sewage still lacks suitable means and suitable equipment facilities, and a large gap exists particularly in the aspect of emergency treatment equipment.
