Description

Technical Field

[0001] The invention relates to the technical field of water treatment, and in particular to a water purification treatment system combined with biomass charcoal and microorganisms. Background Art

[0002] With the rapid development of industrialization and urbanization, water pollution is becoming increasingly serious. Traditional water treatment methods such as chemical precipitation, adsorption, and membrane filtration have problems such as high cost, low efficiency, and secondary pollution. For example, although chemical precipitation can effectively remove heavy metals in water, it will produce a large amount of chemical sludge, increasing treatment costs and environmental burdens. Although adsorption can effectively remove organic pollutants, the regeneration and replacement costs of the adsorbent are high, and the adsorbent itself may become a secondary pollution source. Although membrane filtration technology can achieve a higher water purification effect, the membrane material is prone to clogging and requires frequent cleaning and replacement, with high maintenance costs.

[0003] In order to solve the above problems, in recent years, biochar, as a new type of environmentally friendly material, has been widely studied and used in the field of water treatment due to its good adsorption properties and microbial attachment ability. Biochar can be prepared by pyrolysis of biomass raw materials such as agricultural and forestry waste. It can not only effectively remove organic pollutants and heavy metals in water, but also has the advantages of low cost and renewability. At the same time, microorganisms have unique advantages in degrading organic pollutants, which can further improve water treatment efficiency.

[0004] However, there are certain limitations in using biochar or microorganisms alone for water treatment. Although biochar has good adsorption ability, its adsorption capacity is limited, and regeneration treatment is required after adsorption saturation. Although microorganisms can degrade organic pollutants, their growth and metabolism require specific environmental conditions, and the degradation efficiency of certain pollutants is limited. Therefore, technicians in this field provide a water purification system combined with biochar and microorganisms to solve the problems raised in the above background technology. Summary of the invention
