There are many methods for disinfecting hospital wastewater, broadly categorized into physical and chemical methods. Physical methods include radiation, ultraviolet light, heating, and freezing. Physical methods are generally suitable for smaller volumes of wastewater, and their treatment effect is often less pronounced than chemical methods. However, a significant advantage is
The choice of process generally depends on the hospital’s size, nature, and wastewater discharge destination. There are four main types of processes: primary treatment with enhanced treatment effects, secondary treatment, simplified biological treatment, and advanced treatment. Hospital wastewater treatment typically involves engineering design, construction, and acceptance procedures. Treatment facilities require
Hospital wastewater (commonly known as hospital sewage) refers to various types of wastewater discharged by hospitals into the natural environment or urban pipe systems. It has wide-ranging sources, complex composition, and high risks of infectiousness, toxicity, and radioactivity, requiring strict treatment before discharge. The nature of hospital sewage refers to
Mine water refers to all types of water that flow into underground tunnels or open-pit mines during the mining process, and is considered an unconventional water source. It mainly originates from atmospheric precipitation, surface water, groundwater, fault water, and water from mined-out areas. Based on water quality characteristics and the
1. High-Iron and Manganese Mine Water: Iron and manganese mine water in coal mines is mainly formed by the infiltration of iron and manganese-bearing groundwater from the strata. The iron and manganese in the mine water exist in the form of divalent iron or divalent manganese. Due to the effects
After prolonged filtration, a significant amount of sludge accumulates on the surface of the filter sand layer, clogging it and causing increased operating pressure, slower filtration speed, and a rising filtration level. Backwashing is then necessary. A high-volume backwash pump pumps filtered clean water into the filter from the bottom,
There are many methods for treating aquaculture wastewater, which can generally be categorized into four main types: biological treatment, physical treatment, chemical treatment, and natural treatment. 1. Biological Treatment: This method uses the metabolic activity of microorganisms to transform organic pollutants in solution, colloid, and finely suspended states in wastewater
1. It has a high concentration of organic matter, a lot of suspended solids, and a dark color. It contains a large amount of animal feces, resulting in a very high concentration of NH3-N, and also contains a large number of pathogenic bacteria. 2. The pollutants in the wastewater mainly
I. Types of Livestock and Poultry Wastewater 1. Based on the type of livestock and poultry raised, livestock and poultry wastewater can be classified into: chicken wastewater, duck (goose) wastewater, rabbit wastewater, pig wastewater, cattle wastewater, and sheep wastewater. The water quality varies for each type of wastewater, but the
Ozone reaction towers have been widely used in various fields due to their strong oxidizing properties, efficient sterilization, and environmentally friendly and pollution-free characteristics. The following is a detailed summary of its core application scenarios:
