Anonymous users2024-02-10Sewage treatment is to use different ways to separate the pollutants contained in the sewage or convert them into harmless substances, so that the sewage can be purified, and the sewage is generally treated by physical, chemical or biological methods.
1. Physical method: the use of physical action to treat, separate and improve the pollutants in wastewater.
For example, the precipitation method (gravity separation method) removes suspended solids in water with a relative density greater than 1.
Filtration (activated carbon in the sand layer of the strainer) removes suspended solids from the water.
The evaporation method is used to concentrate non-volatile and insoluble substances in wastewater.
In addition, there are centrifugal separation method, vapor flotation (flotation) method, high gradient magnetic separation method, etc.
2. Chemical method: the use of chemical reaction or physicochemical action to treat ** soluble waste or colloidal substance.
For example, the neutralization method is used to neutralize acidic or alkaline wastewater. The extraction method uses the "allocation" of soluble wastes with different solubility in the two-phase interaction, such as phenols and heavy metals.
The redox method is used to remove reducing or oxidizing pollutants in wastewater and kill pathogenic bacteria in natural water bodies. In addition, there are coagulation methods and chemical precipitation methods.
3. Physicochemical method: adsorption method, ion exchange method, extraction method, membrane separation method, evaporation method.
4. Biological method: the use of microbial biochemical action to treat organic pollutants in wastewater.
For example, biological filtration and activated sludge are used to treat domestic sewage or organic production wastewater, so that organic matter can be converted and degraded into inorganic salts and purified. In addition, there is also the biofilm method and the biopond method.
5. Sludge land treatment method: used for organic matter treatment. Sewage irrigation, slow infiltration, rapid infiltration.
Different sewage treatment processes choose different principles, generally according to the amount of water per unit of sewage treatment, pollutants, power consumption per treatment unit, cost, floor area, management and maintenance difficulty.

Anonymous users2024-02-08I don't know what kind of one you needThere are several wastewater treatment processes that you can take a look at.
1. The adaptation conditions of BOD, this problem is quite strange, generally speaking, if you want to deal with a kind of water, the higher the BOD, the better, because it proves that the biodegradability of this water is strong, and the treatment efficiency is high in biological contact oxidation, biological turntable, biofilm, and activated sludge. >>>More
Sewage treatment equipment can be roughly divided into sewage pretreatment equipment and sludge treatment equipment. The sewage pretreatment equipment mainly includes sewage blocking equipment, sand sinking equipment, sand discharge equipment, sedimentation equipment, and air flotation equipment. It mainly includes blast aeration equipment, decanter, biofilm wastewater treatment equipment, anaerobic wastewater treatment equipment, and typical auxiliary equipment for anaerobic anoxic treatment. >>>More

See how sewage turns decay into magic?
The main purpose of medical sewage treatment is to disinfect and kill pathogens in medical sewage to prevent pathogens from causing infectious diseases. Medical sewage disinfection is generally carried out by drug disinfection.
