Abstract
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...
