Treatment system for removing detergent from domestic wastewater

Abstract

The invention discloses a treatment system for removing a detergent from domestic wastewater. The treatment system comprises a pretreatment unit, a primary filter tank, a primary sedimentation tank, a pH value regulating tank, an ion-Hall effect separating tank, an aeration nitrification tank, a biological denitrification tank, a secondary sedimentation tank, a clean water tank and the like. The system creatively utilizes the electromagnetic induction phenomenon called the Hall effect, when current is perpendicular to an external magnetic field to be conducted in a wastewater tank, a carrier can deflect, and an additional electric field can be produced in the direction perpendicular to the current and the magnetic field. The potential difference can be produced in the vertical direction of the wastewater tank as long as an electromagnet and a discharge electrode are placed in proper positions and the magnetic induction line and the current perpendicularly pass through the wastewater tank in two horizontal directions, so that washing substance ions in wastewater move downwards and are enriched at the bottom of the wastewater tank to form sludge substances gradually, and the detergent is removed from the wastewater.

Description

technical field [0001] The invention relates to a treatment system 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
