Liaoning Shenyang Specialized Hospital Sewage Treatment Equipment Material

Liaoning Shenyang Specialized Hospital Sewage Treatment Equipment Material

Product Introduction

hospitalThe wastewater treatment equipment adopts Xianjin's biological treatment process. Based on the summary of the operating experience of domestic and foreign domestic wastewater treatment devices, combined with our own scientific research achievements and engineering practice, we have designed a complete set of organic wastewater treatment devices that can be buried underground. It integrates the removal of BOD5, COD, and NH3-N, and has stable and reliable technical performance and treatment capabilitieseffectGood, cost-effective, automated operation, easy maintenance and operation, no land occupation, no need for building, no need for heating and insulation, and other advantages. Flowers and grass can be planted on the ground without affecting the surrounding environment.

working principle

This device is generally buried underground and uses a secondary biological contact oxidation treatment process. Its treatment effect exceeds that of a fully mixed biological oxidation tank, and its adaptability to water quality is high, ensuring the stability of water treatment. The device uses a new type of highly effective elastic three-dimensional packing material in the pool, which has a strong removal function for organic substances in sewage. After oxidation treatment, the device produces less sludge and only needs to be discharged once every 90 days. In order to prevent the breeding and transmission of released pathogens, it is necessary to carry out deep disinfection treatment on water quality. At present, the commonly used disinfection processes include ultraviolet disinfection, chlorine dioxide disinfection, and ozone disinfection. Hospitals need to choose based on the characteristics of sewage quality and discharge volume.

Product Features

1. The equipment buried underground can be used as green land, saving the hospital space.

2. The sewage integrated equipment is made of corrosion-resistant and antioxidant materials, with a long service life, saving operating costs for hospitals.

3. By combining biological contact oxidation tanks with layer by layer filtration and disinfection devices, the sewage treatment effect is excellent, solving the problem of bacterial transmission.

4. This device has good deodorization effect and produces a small amount of sludge, which will not cause other pollution hazards to the environment.

5. Fully automatic control system, installation of damage alarm system, no need for manual supervision, saving labor input.

processing standard

1. The new standards comprehensively control the sewage, exhaust gas, and sludge generated by hospitals, emphasizing the disinfection effect on pathogen containing sewage while also considering ecological environment safety.

2. In terms of biological indicators, the new standard sets different requirements for hospital wastewater discharged into sewers and water bodies. The new standard strictly distinguishes the nature of hospitals and divides them into two levels based on the destination of sewage, and proposes strict control indicators for each level on the basis of the original standard.

3. The new standard considers disinfection effectiveness and ecological safety issues, and specifies the disinfection time and residual chlorine amount for different types of hospitals and sewage destinations, strictly setting the upper limit of residual chlorine standards.

4. In terms of physical and chemical indicators, strict control has been implemented on the COD, BOD5, SS, animal and vegetable oils, petroleum products, anionic surfactants, and other indicators of hospital sewage and infectious disease hospital sewage discharged into surface water bodies, based on the original standards, to enhance the wind resistance of the sewage treatment system. Considering that ammonia nitrogen also consumes disinfectants, strict requirements have been put forward for ammonia nitrogen.

Processing pharmaceuticals

According to the different uses of drugs, they can be divided into the following categories:

(1) Coagulants: sometimes also known as coagulants, can be used as a means to enhance solid-liquid separation, in processes such as primary sedimentation tanks, secondary sedimentation tanks, flotation tanks, and tertiary or deep treatment.

(2) Coagulant aid: The auxiliary flocculant plays a role and enhances the coagulation effect.

(3) Conditioning agent: also known as dehydrating agent, used for conditioning the remaining sludge before dewatering. Its varieties include some coagulants and coagulants mentioned above.

(4) Emulsifier: sometimes also known as a destabilization agent, mainly used for pre-treatment of oily wastewater containing emulsified oil before water flotation. Its varieties include some coagulants and coagulants mentioned above.

(5) Defoamer: mainly used to eliminate a large amount of foam in the process of aeration or mixing.

(6) PH adjuster: used to adjust the pH value of acidic and alkaline wastewater to neutral.

(7) Redox agent: used for the treatment of industrial wastewater containing oxidizing or reducing substances.

(8) Disinfectant: Used for disinfection treatment after wastewater treatment before discharge or reuse.
