Problems solved by technology

The defect of the Fenton oxidation method is that the treatment effect of organic waste liquid with large composition changes is not ideal
The disadvantages of the above method are: when the discharge standard is high, it is difficult to ensure that the waste water is discharged up to the standard
The disadvantages of the above processing methods are: complicated operation and high cost
Because the composition of organic waste liquid is complex and changeable, it is difficult to operate and costly to add and cultivate targeted bacteria.

Embodiment 1

[0039] Adopting the organic waste liquid treatment process of the present invention to process the organic waste liquid of a certain factory comprises the following steps:

[0040] a. Acid analysis treatment: In the pH adjustment tank, mix the organic waste liquid and the stripping waste liquid according to the ratio of organic waste liquid / stripping waste liquid ≤ 1.5%, and add sulfuric acid to adjust the pH to 2-3; mix the two The liquid is transported to the acid analysis tank, and the filter aid ferrous sulfate is added at 1.3~1.6kg / m 3 , stirring for 60 to 120 minutes;

[0041] b. Filtration: transfer the waste liquid treated by acid analysis in step a to the filtration system for filtration, and remove the sediment. At this time, the COD content of the filtrate is ≤3000mg / L;

[0042] c. Broken network treatment: mix the organic waste water with the above-mentioned filtrate in the wastewater regulating tank, the mixing amount of the filtrate is ≤15%, add the mixed solut...

Abstract

The invention discloses an organic waste liquid treatment process, and belongs to the technical field of waste water treatment. The treatment process is mainly characterized in that organic waste liquid and demolding waste liquid are mixed; then, technical treatment such as acid separation treatment, filtration, complex breaking treatment, coagulating sedimentation and biochemical treatment is performed until the standard reaching discharging; organic matters in the water can be efficiently and thoroughly removed, so that the treated water quality can be discharged in the standard reaching way; in addition, waste resources are reasonably utilized; the goal of treating waste by waste is achieved; the operation is simple; the investment is low; the cost is low.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an organic waste liquid treatment process. Background technique [0002] The production process of circuit boards has many procedures and complex processes, and many types of chemicals are used. In addition to the discharge of cleaning wastewater with a low concentration of pollutants, some high-concentration waste liquids, including high-concentration organic waste liquids, will also be discharged during production. The composition of organic waste liquid is complex and its content varies greatly. Some are oxidizing substances, some are reducing substances, and also contain heavy metals and complexes. Only part of the organic matter can be removed by acid analysis, so only a single process is used to treat organic waste liquid is usually less effective. [0003] For organic waste liquids with stable components, Fenton's reagent can generally be used for oxidation ...
