What Water Treatment Equipment is Needed for Sewage Treatment in the Medical Industry?

In recent years, as environmental protection and public health gain more spotlight, the proper handling of medical sewage has emerged as a critical concern. Medical wastewater is rife with pathogens, hazardous chemicals, and heavy metals. If left untreated or inadequately treated, it can unleash serious risks to the ecological environment and human well - being. Thus, the selection of suitable water treatment equipment is of paramount significance.

Primary Sedimentation Tanks

The primary sedimentation tank serves as the vanguard in medical sewage treatment. This large - scale apparatus harnesses the power of gravity to make heavier solid particles in the sewage sink to the bottom. By eliminating these sizeable solids at the outset, it safeguards downstream treatment equipment from potential damage and eases the burden on the entire treatment system.

Biological Aeration Tanks

Biological aeration tanks are the workhorses in the treatment process. These tanks leverage aerobic microorganisms to break down organic matter within the sewage. Through a carefully controlled aeration process, oxygen is supplied to these microorganisms. This enables them to decompose harmful substances such as bacteria and viruses into benign by - products like carbon dioxide and water, effectively purifying the sewage.

Disinfection Equipment

Disinfection represents a pivotal stage in medical sewage treatment. Chlorine - based disinfection equipment is widely adopted, as it can efficiently neutralize a wide spectrum of pathogens present in the sewage. Additionally, ultraviolet (UV) disinfection devices have gained popularity. UV rays penetrate the cell walls of microorganisms, disrupting their DNA structure and rendering them incapable of replication.

Membrane Filtration Systems

Membrane filtration systems, encompassing microfiltration, ultrafiltration, and reverse osmosis membranes, are indispensable for removing fine particles, suspended solids, and certain dissolved substances. Microfiltration membranes can sieve out particles as minuscule as 0.1 - 10 micrometers, while ultrafiltration membranes are capable of capturing even smaller molecules and macromolecules, ensuring a high - level of purification.

Chemical Coagulation and Flocculation Equipment

This category of equipment is deployed to introduce coagulants and flocculants into the sewage. Chemicals such as aluminum sulfate and ferric chloride are added to prompt the fine suspended particles in the sewage to agglomerate into larger flocs. These larger flocs are then more readily separated through sedimentation or filtration processes.

Sludge Dewatering Equipment

Throughout the sewage treatment journey, a substantial amount of sludge is generated. Sludge dewatering equipment, such as belt filter presses and centrifuge dewatering machines, is employed to reduce the moisture content of the sludge. This not only streamlines the subsequent disposal of sludge but also cuts down on transportation costs.

pH Adjustment Tanks

Medical sewage often exhibits an abnormal pH value. pH adjustment tanks are utilized to introduce acidic or alkaline substances, calibrating the pH of the sewage to an optimal range for subsequent treatment processes. This step is crucial for ensuring the efficacy of biological treatment and the overall stability of the treatment system.

Monitoring and Control Systems

Sophisticated monitoring and control systems are installed to continuously assess the quality of the sewage at various treatment stages. These systems can detect key parameters such as chemical oxygen demand (COD), biochemical oxygen demand (BOD), and the concentration of various pollutants. Relying on the real - time monitoring data, the operation of the treatment equipment can be promptly adjusted, ensuring the smooth and stable operation of the entire treatment process.

In summary, treating medical sewage demands an integrated suite of water treatment and sewage treatment equipment. These components work in tandem to ensure that medical sewage is treated to meet environmental discharge standards, thereby safeguarding the environment and public health. As technology marches forward, the medical industry can anticipate even more efficient and innovative water treatment solutions.
