Wastewater purification apparatus and wastewater treatment process

Abstract

The present invention belongs to the technical field of industrial wastewater purification, and particularly relates to a wastewater purification apparatus and a wastewater treatment process. The wastewater purification apparatus is characterized by comprising a wastewater box, an oil-water separation device, a flocculation tower, a press filter, an aeration tower, a catalytic oxidation tower, an ultra-filtration tank, and a purified water tower, wherein the wastewater box is connected with the oil-water separation device through a pipeline, the bottom portion of the wastewater box is connected with the outlet of the press filter through a pipeline, the flocculation tower and the press filter are connected through a circulating pipeline, the outlet of the flocculation tower and the inlet of the aeration tower are connected through a pipeline, the bottom end of the flocculation tower is respectively connected with the bottom end of the aeration tower and the bottom end of the catalytic oxidation tower, the outlet of the aeration tower and the inlet of the catalytic oxidation tower are connected, the outlet of the catalytic oxidation tower and the inlet of the ultra-filtration tank are connected, and the ultra-filtration tank and the purified water tower are connected. The wastewater purification apparatus and the wastewater treatment process of the present invention have the following beneficial effects that: the super oxidation method is used, the industrial wastewater can be treated to achieve the colorless and clarified state so as to achieve the industrial water and reuse, and the State Environmental Protection Agency standards are met.

Description

technical field [0001] The invention belongs to the technical field of industrial wastewater purification, and in particular relates to a wastewater purification device and a treatment process thereof. Background technique [0002] Rubber is a product widely used in daily life, but in the production process, the COD and ammonia nitrogen concentrations in rubber regeneration wastewater are high, and the biodegradability is poor, making the post-treatment of wastewater a very important process. At present, the conventional wastewater treatment equipment adopts the traditional chemical oxidation method, which is a non-selective oxidation of a wide range of organic matter. Under necessary conditions, the organic pollutants will be mineralized into carbon dioxide and water, and the inorganic matter can also be oxidized or convert. However, due to the high concentration of COD and ammonia nitrogen in the rubber regeneration wastewater, the biodegradability is poor, and the odor a...

AI Technical Summary

Problems solved by technology

However, due to the high concentration of COD and ammonia nitrogen in the rubber regeneration wastewater, the biodegradability is poor, and the odor and color are difficult to meet the standards. Its disadvantages are high equipment investment and high operating costs.

In particular, the wastewater COD and ammonia nitrogen of reclaimed rubber have the characteristics of high concentration and poor biodegradability, making its purification treatment a difficult problem in the field of environmental protection in the world. Wastewater purification treatment cannot meet the standards of the National Environmental Protection Agency.
