Problems solved by technology

[0005] The sewage treatment methods used in industry on the market are generally able to meet the national discharge standards, but the sewage treatment methods used in industry on the market now only need to meet the standards, and generally do not consider the sewage as thoroughly as possible. deal with
Moreover, the sludge output of pilot sewage treatment on the market is still relatively high, which leads to higher costs

Abstract

The invention discloses a printing and dyeing waste water treatment process, and solves the problem the existing treatment effects of the printing and dyeing waste water are not good. The printing and dyeing waste water treatment process comprises the steps that 1, in the pretreatment process, impurities in the waste water are removed, and the decoloration process is conducted to a certain degree, and loads of subsequent treating processes are reduced; 2, in the biochemical treatment process, organic pollutants in waste water are degraded; 3, in the advanced treatment process, the impurities, the organic pollutants and chroma in the waste water are further removed. The problems in the prior art are well solved by the above scheme.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a printing and dyeing wastewater treatment process. Background technique [0002] With the development of industry, the pollution control brought by industry has become an important topic today, and sewage treatment is an important part of it. The effect of sewage treatment is generally shown by water quality indicators such as COD and BOD. In addition, because sewage generally contains sludge, and sludge treatment is a high-cost item, therefore, reducing costs and reducing sludge production are also important indicators to show the effect of sewage treatment. [0003] The water quality of printing and dyeing wastewater is complex, and the pollutants can be divided into two categories according to the source: one is the entrainment of the fiber raw material itself; the other is the slurry, oil, dye, chemical additives, etc. used in the processing process. The character...
