Embodiment 1

[0083] The sewage collected in this embodiment all comes from Yongning County Industrial Park, wherein industrial wastewater accounts for more than 60%, and the rest is domestic sewage.

[0084] The specific process is as follows:

[0085] The invention provides a continuous treatment process for high COD in industrial waste water, which comprises the steps of:

[0086] S1: the industrial waste water enters the middle lifting pump pool 2 through the middle lifting pump 26, and then enters the water distribution well 3;

[0087] S2: Before entering the water distribution well 3, measure the COD content in the industrial wastewater by the water quality online detector, the COD content is 500mg / L, and calculate the amount of copper oxide and hydrogen peroxide that needs to be added. The measured industrial wastewater is transported from the water distribution well 3 to the front-end sump 15 of the UV synergistic advanced oxidation pool 4, and the dosing system 6 adds a certain a...

Abstract

The invention provides a continuous treatment system and treatment process for high-concentration chemical oxygen demand (COD) in industrial wastewater. The continuous treatment system comprises a middle lifting pump pool, a water distribution well and an ultraviolet (UV) collaborative advanced oxidation pool, a catalyst dehydration system and a catalyst regeneration system; an outlet of the middle lifting pump pool is connected with an inlet of the water distribution well; an outlet of the water distribution well is connected with an inlet of the UV collaborative advanced oxidation tank; an outlet of the UV collaborative advanced oxidation tank is connected with an inlet of the catalyst dehydration system; an outlet of the catalyst dehydration system is connected with an inlet of the catalyst regeneration system; and an outlet of the catalyst regeneration system is connected with an inlet of the water distribution well. The treatment system and treatment process provided by the invention are convenient to operate and manage, the process is stable, and wastewater containing COD which is difficult to treat can be treated, so that the COD content in the wastewater reaches a first-level standard A.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment, in particular to a continuous treatment system and process for high-concentration COD in industrial wastewater. Background technique [0002] With the rapid development of industry, my country has achieved rapid economic growth, while environmental pollution has also become a problem left over from the past. After several years of hard work, my country has made great achievements in urban sewage treatment technology, with fruitful results. As a "blue ocean" yet to be developed, the water treatment market has a very optimistic prospect. According to the "Market Prospect and Investment Analysis Report of China's Sewage Treatment Industry" by Qianzhan Industry Research Institute, there are more than 4,000 waterworks and more than 3,500 sewage treatment plants in my country. With the gradual improvement of sewage treatment facilities, the sewage treatment rate in my country has now rea...
