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 wastewater, and belongs to the field of wastewater 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 interface adsorption performance, which can significantly reduce the surface tension of solvents or liquid-liquid, liquid-solid interfacial tension. Its molecular structure contains organic compounds with two parts: hydrophilic group and lipophilic group. When surfactants are dissolved in water, they are divided into ionic surfactants and non-ionic surfactants according to whether they generate ions and their electrical properties. Classified according to the dissociation properties of polar groups, surfactants include ionic surfactants, non-ionic surfactants, and special surfactants.

Embodiment Construction

[0020] Such as figure 1 The shown treatment system for removing detergent from domestic wastewater includes a pretreatment unit 1, a primary filter tank 2, a primary sedimentation tank 3, a pH adjustment tank 4, an ion-Hall effect separation tank 5, and an aeration and nitrification tank 6. Biological denitrification tank 7, secondary sedimentation tank 8, purification tank 9, etc.; among them, the domestic wastewater containing detergent enters the pretreatment unit 1 through the wastewater pipeline, where it is collected and initially stabilized, and the pretreatment unit The outlet of 1 is connected to the primary filter tank 2 through the wastewater pipeline, where large-diameter solid matter in domestic wastewater is removed, and the outlet of the primary filter tank 2 is connected to the primary sedimentation tank 3 through the wastewater pipeline, where insoluble substances in the wastewater are further removed. The outlet of the sedimentation tank 3 is connected to the p...
