What is used for sewage disinfection equipment? What disinfectant is used in hospital sewage?

It is recommended that you choose DCW hypochlorous acid generator equipment, because it can generate hypochlorous acid solution with an effective chlorine concentration of up to 800ppm through electrolysis of salt and water, quickly decompose the organic matter in the sewage, and can kill various bacteria, viruses, fungi and other microorganisms in the sewage efficiently, quickly and broad-spectrum, without producing new harmful residues, to ensure that the sewage meets the national discharge standards.

Sewage disinfection equipment generally uses disinfectants in circulating water to disinfect.

Sewage disinfection equipment is used for reasonable disinfection with very professional disinfection things, and they are all sold with disinfectants pulled by very large vehicles.

Hospital wastewater can generally be treated with small integrated biochemical equipment, and chlorine dioxide is generally used for disinfectants.

You should use professional sewage disinfection equipment, and you should choose the corresponding equipment according to the amount of sewage you treat.

The bacteria in the wastewater are high in species, coupled with the presence of bacterial film, so the ordinary disinfectant is not completely sterilized, and it may also cause chemical residues and affect the environment. DCW hypochlorous acid solution can solve the above problems, this is because the sterilization efficiency of hypochlorous acid is dozens of times that of sodium hypochlorite, the sterilization effect is stable, it has been used for 7 years, and it is still being used.

You can contact specialized professional companies, professional decontamination equipment, large-scale disinfection facilities, and learn disinfection techniques at the same time.

Hello, the current chlorine dioxide disinfection and sterilization performance is good, chlorine dioxide is a high-efficiency disinfection and sterilization agent, it can kill all microbial colonies and viruses, now there is a stable chlorine dioxide disinfection powder, high content and easy to operate, find a complete qualification.

The commonly used disinfection processes for hospital sewage disinfection include chlorine disinfection (such as chlorine, chlorine dioxide, sodium hypochlorite), oxidant disinfection (such as ozone, peracetic acid), and radiation disinfection (such as ultraviolet rays, radiation).

Disinfection and sterilization performance of chlorine dioxide Chlorine dioxide is the only highly effective disinfectant among chlorine-containing disinfectants internationally recognized, which can kill all microorganisms.

Hospital sewage, in addition to general domestic sewage, also contains chemicals, radioactive wastewater, and pathogens. Therefore, it must be treated before it can be discharged, especially the sewage discharged from infectious disease wards such as hepatitis must be disinfected before it can be discharged. The functions, facilities and personnel composition of each department of the hospital are different, and the main departments and facilities that produce sewage are:

Drainage of treatment rooms, laboratories, wards, laundry rooms, X-ray imaging processing, animal rooms, isotope ** diagnosis, operating rooms, etc. The composition and amount of sewage generated by different departments and departments are different, such as heavy metal wastewater, oily wastewater, printing wastewater, radioactive wastewater, etc.

There are three types of basic methods for medical wastewater treatment: physical method, chemical method and microbial method, at present, hospitals use more chemical methods, and physical methods are mainly for hospital wastewater precipitation, separation, cold and heat treatment and other operations. Chemical methods are more widely used in hospital wastewater treatment, and the commonly used methods include:

Chlorination disinfection, oxidant disinfection, radiation disinfection, etc., microbial treatment method has gradually been favored by people as a method with high added value of current science and technology.

Physical processing methods.

1.Precipitation filtration.

The sedimentation method is an important aspect of the physical treatment of medical wastewater, and the main principle is to use the different densities and pollutants of suspended sewage in medical wastewater to separate the suspended solids in medical wastewater according to the principle of gravity sinking and floating. Filter media is used to intercept suspended solids in sewage. The filter medium includes steel strips, screens, abrasive cloths, plastics, microporous tubes, etc., and the commonly used filtration equipment includes grids, grids, microfilters, sand filters, vacuum filters, filter presses, etc., to separate the sewage.

Summary. Ozone: Advantages: Strong oxidizing ability, short contact time; No organochlorides are produced; Not affected by pH; It can increase dissolved oxygen in water.

Ozone: Advantages: Strong oxidizing ability, short contact time; No organochlorides are produced; Not affected by pH; It can increase dissolved oxygen in water.

Effect: The effect of sterilization and virus killing is very good.

Ultraviolet light: Advantages: No harmful residues; Odorless; Simple operation and easy to automate; Low operation management and maintenance costs.

The effect is good, but there are requirements for the concentration of suspended solids.

Chlorine dioxide: advantages: strong oxidation, no organic chloride (THMS); The delivery is simple and convenient; Not affected by pH;

It has a better sterilization effect than Cl2.

Trichloroisocyanuric acid: advantages: high available chlorine content, stable storage and transportation, easy molding and use, high sterilization and bleaching power, long release of available chlorine in water, safe and non-toxic.

Effect: It is very effective in sterilization and virus destruction.

Sodium hypochlorite: Advantages: Non-toxic, non-hazardous in operation and management.

Effect: Same as Cl2 sterilization.

Potassium persulfate complex salt: advantages: strong oxidizing ability; Long-lasting effect; The equipment is easy to operate and easy to maintain; Safe and non-toxic effect: stronger than ordinary chlorine disinfectant.

To sum up, the above several sterilization and disinfection methods can meet the discharge standards of medical wastewater and meet the requirements of technical specifications, among which potassium persulfate complex salt is more recommended among several common disinfection methods, it will not produce secondary pollutants, and can achieve a strong disinfection effect at low concentration, and has an inactivation effect on a variety of germs and viruses, and is more suitable for sterilization and disinfection of medical wastewater.

Chlorine dioxide disinfectant is indeed a better green disinfectant at present.

Generally, hospitals with a small amount of sewage will use a stable chlorine dioxide solution. Large hospitals generally have chlorine dioxide generators to produce chlorine dioxide for disinfection!!

Use ultraviolet disinfection, chlorine dioxide generators need to purchase hydrochloric acid, the procedures are very troublesome and not easy to keep.
