There are several types of sewage treatment agents
Sewage treatment agents are chemicals used to treat pollutants and waste in sewage. According to different treatment targets and the nature of pollutants, there are many types of sewage treatment agents to choose from. The following is a common sewage treatment agent:
Oxidation agent: Oxidant can promote the degradation and decomposition of organic matter. Common oxidants include hydrogen peroxide, ozone, and manganate.
Against agent: The condenser is used to condense the suspended solids and colloidal substances into large particles, which is convenient for subsequent precipitation or filtration. Common condensation agents include flocculant (such as polymer aluminum salt, polyacrylamide, etc.) and flocculant (such as iron chloride, polymer silicate, etc.).
PH regulator: By adjusting the acid -base conditions of sewage, it will help optimize the sewage treatment process. Common pH regulators include alkaline substances (such as sodium hydroxide, calcium hydroxide) and acidic substances (such as sulfuric acid).
Fermentation agent: It is suitable for treatment of high concentration wastewater containing organic matter, and microorganisms are used for degradation and transformation. Common fermented agents include molds and lactic acid bacteria.
Biological preparations: used to increase and promote microbial activity and degradation capabilities in the sewage treatment system. Common biological agents include bacterial agents and enzyme agents.
Substant: It is used to promote the precipitation of suspension in the sewage and form a sludge. Common sedibles include iron hydroxide and calcium hydroxide.
Ion exchanges: used to remove ionic pollutants in sewage, such as heavy metal ions, ammonia nitrogen, etc. Common ion exchanges include activated carbon and resin.
The above -mentioned potions can be used separately or in combination according to the specific situation to meet the requirements of sewage treatment. It must be noted that when selecting and using sewage treatment agents, relevant regulations and standards should be followed, and the water quality after treatment meets the emission standards. At the same time, it is recommended to consult a professional environmental engineer or water treatment expert to ensure safe and efficient sewage treatment before using sewage treatment agents.
