Treatment of medical wastewater by screw press
screw press is suitable for municipal sewage, domestic sewage, food, beverage, chemical industry, leather, welding consumables, papermaking, printing and dyeing, pharmaceuticals, electroplating, oil fields, coal mines, winemaking, animal husbandry, kitchen wastewater, water plants, power plants, steel plants Sludge and sewage treatment in various industries.
Characteristics of hospital wastewater:
Hospital sewage mainly refers to the sewage discharged from the clinics, laboratories, wards, laundry rooms, X-ray photography rooms and operating rooms of hospitals or other medical institutions. Due to its particularity, hospital sewage contains a variety of pathogenic bacteria, viruses, parasite eggs, some toxic and harmful substances, radioactive pollutants, etc., which are highly infectious. In particular, the sewage of infectious disease hospitals contains a large number of pathogenic microorganisms and viruses, toxic and harmful substances. If they are discharged into urban sewers or environmental water without disinfection treatment, these viruses, germs and parasite eggs will become a concentrated secondary pollution source in the environment, causing the occurrence and spread of various diseases and seriously threatening the human body. healthy. Therefore, the safe and stable treatment of hospital sewage is very important.
The sewage of medical institutions contains toxic and harmful substances such as acid, alkali, suspended solids, BOD, COD and animal and vegetable oils. The quality of medical wastewater is similar to domestic sewage, but it is more complicated than the discharge of general domestic sewage. At the same time, the sewage of medical institutions is contaminated by pathogenic microorganisms such as feces, infectious bacteria and viruses. It is contagious and can induce disease or cause injury. Security risks.
Treatment of medical wastewater by screw press:
Hospital wastewater is mainly composed of medical wastewater and domestic wastewater. Screw press is used in the sludge dewatering process in sewage treatment. The amount of sludge in hospital wastewater is generally not large, so the general model of screw press selected is generally small. , like TNW131 or TNW201, it is completely satisfied.
1. There is a certain odor in the pharmaceutical production wastewater. We will be stimulated to a certain extent when operating the equipment. The screw press has a high degree of automation and can realize unattended automatic operation so that we can reduce possible problems in the operating environment.
2. The screw press is made of stainless steel, which has a long service life, is not easy to corrode and has strong wear resistance, and has no wearing parts and is relatively low in after-sales cost.
3. The screw press adopts the principle of screw shaft and ring-piece extrusion, which can effectively operate the oily nature of the sludge in the pharmaceutical industry without blocking the shaft and the shaft, and is convenient for cleaning, operation and maintenance.
