Problems solved by technology

[0002] At present, decoration produces sewage, and decoration sewage is often discharged without treatment, which will seriously deteriorate the indoor air quality of the entire corridor and seriously affect the relationship between neighbors. Moreover, decoration sewage is toxic to microorganisms. Formaldehyde and paint cannot be directly biochemically treated

Embodiment 1

[0016] A treatment method for decoration sewage, comprising the following steps:

[0017] 1) Add citric acid to the decoration sewage to adjust the pH value to 6.5, add 5% cationic starch to centrifuge at 2500r / min, add 0.1% acetylacetone by weight, let it stand for 2 days, and then filter the sewage Filter to obtain pretreated sewage and paint residue;

[0018] 2) pour aseptic vermiculite into the pretreated sewage of step 1) gained, make diatom ooze do not cross the pretreated sewage, add the dried lotus root powder of 10% weight, then add the EM bacterium of 0.15% weight, stir evenly, use Cover the diatom mud with clean straw, let it stand in a cool place for 3 days, remove the straw, and put it in the sun for 3 days to get fermented vermiculite;

[0019] 3) Mix the paint slag obtained in step 1) with diatomaceous earth at a ratio of 1:1, then add 10% by weight of egg shells, 5% by weight of hosta flowers, and 7% of reeled silk flowers, mix and pulverize them, pass through...

Embodiment 2

[0025] A treatment method for decoration sewage, comprising the following steps:

[0026] 1) Add citric acid to the decoration sewage to adjust the pH value to 6.7, add 8% cationic starch to centrifuge at 2500r / min, then add 0.1% acetylacetone by weight and let it stand for 3 days, then filter the sewage Filter to obtain pretreated sewage and paint residue;

[0027] 2) pour aseptic vermiculite into the pretreated sewage of step 1) gained, make diatom ooze have not crossed the pretreated sewage, add the dried lotus root powder of 12% weight, then add the EM bacterium of 0.18% weight, stir evenly, use Cover the diatom mud with clean straw, let it stand in a cool place for 5 days, remove the straw, and put it in the sun for 4 days to obtain fermented vermiculite;

[0028] 3) Mix the paint slag obtained in step 1) with diatomaceous earth at a ratio of 1:1, then add 11% by weight of egg shells, 6% by weight of hosta flowers, and 8% of silk reeling flowers, mix and pulverize them, ...

Abstract

Belongings to the field of environmental protection, the invention in particular relates to a decoration sewage treatment method. According to the decoration sewage treatment method provided by the invention, the liquid and solid of decoration sewage are treated separately, a microbial fermentation method is utilized to greatly reduce the formaldehyde content of decoration sewage and further decompose solid in the decoration sewage, and finally harmless treatment is carried out on the decoration sewage to reduce environmental pollution of decoration sewage.

Description

【Technical field】 [0001] The invention belongs to the field of environmental protection, and in particular relates to a treatment method for decoration sewage. 【Background technique】 [0002] At present, decoration produces sewage, and decoration sewage is often discharged without treatment, which will seriously deteriorate the indoor air quality of the entire corridor and seriously affect the relationship between neighbors. Moreover, decoration sewage is toxic to microorganisms. Formaldehyde and paint cannot be directly biochemically treated. 【Content of invention】 [0003] In view of the above problems, the present invention provides a treatment method for decoration sewage, which is scientific and reasonable, can reduce the content of formaldehyde and paint in decoration wastewater, and reasonably treat the mixture containing decoration sewage treatment, which is safe and environmentally friendly. Harmless treatment of decoration sewage treatment mixture; [0004] A t...
