Treatment method for removing detergent in domestic wastewater

Abstract

The invention discloses a treatment method for removing detergent in domestic wastewater. The treatment method includes: allowing the domestic wastewater containing the detergent to sequentially pass a preprocessing unit, a primary filter tank, a primary settling tank, a pH regulating tank, an ion-Hall effect separation tank, an aeration nitration tank, a biological nitrogen removal tank, a secondary settling tank, a purified water tank and the like. The treatment method has the advantages that the method creatively uses an electromagnetism induction phenomenon called Hall effect, when currents transmit in a wastewater tank in a way that the currents are vertical to an outer magnetic field, a carrier deflects, and an additional electric field is generated in the direction vertical to the currents and the magnetic field; as long as an electromagnet and an discharge electrode are respectively placed at appropriate positions to allow the magnetic induction line direction and the current direction to vertically pass the water tank along two horizontal directions, potential difference can be generated in the vertical direction of the water tank, the detergent ions in the waste water are allowed to move downwardly and be enriched at the bottom of the water tank to gradually form sludge, and accordingly the detergent is removed from the wastewater.

Description

technical field [0001] The invention relates to a treatment method for removing detergent in waste water, which belongs to the field of waste water treatment in environmental protection. Background technique [0002] The main component of detergent is surfactant. Surfactant refers to a class of substances with certain properties, structure and interfacial adsorption performance, which can significantly reduce the surface tension of solvents or the interfacial tension of liquid-liquid and liquid-solid. Its molecular structure contains two parts of organic compounds, hydrophilic group and lipophilic group. When surfactants are dissolved in water, they are classified into ionic surfactants and nonionic surfactants according to whether they generate ions and their electrical properties. According to the dissociation properties of polar groups, surfactants include ionic surfactants, nonionic surfactants, and special surfactants. [0003] In recent years, my country's chemical s...

Problems solved by technology

Its treatment effect is good, but there are disadvantages such as complicated technology and unstable treatment effect.

[0007] Due to the shortcomings of the above-mentioned traditional treatment methods such as high cost, complicated technology, and unstable treatment effect, it is necessary to get rid of the existing treatment technology ideas, open up a new way to deal with domestic wastewater detergent, and then develop a new form of life Wastewater Detergent Treatment Technology
