Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, and in particular relates to a treatment device for acid washing wastewater containing endocrine disruptors. Background Art

[0002] When treating pickling wastewater containing endocrine disruptors, foam separation process, Fenton oxidation process, A2 / O process and activated carbon filtration process are usually used to remove harmful substances in the wastewater, and then the wastewater is separated into solid and liquid by a filtration mixing device, and the solid metal is recycled. The treated wastewater that meets the requirements can be used again for pipe spray cooling, reducing the cost of wastewater treatment and achieving high efficiency and economy of wastewater treatment.

[0003] The Chinese patent application number CN202222879583.2 discloses a pickling wastewater treatment device, comprising a neutralization box, wherein the four corners of the bottom of the neutralization box are provided with support feet, a water inlet is provided on one side of the neutralization box, a filter screen is provided in the water inlet, and a first motor is provided on the top of the neutralization box;

[0004] The above scheme uses a filter to filter impurities in the pickling wastewater. However, in actual use, impurities accumulate on the filter and are difficult to clean. The accumulation of impurities will lead to a decrease in the efficiency of the pickling wastewater passing through, thereby reducing the efficiency of the pickling wastewater treatment.

[0005] In view of this, the present utility model is proposed. Utility Model Content
