Problems solved by technology

At present, for the treatment of sucralose mother liquor wastewater, most sucralose production enterprises only perform simple pretreatment on the mother liquor wastewater, and the effluent quality is difficult to meet the standard. After pretreatment, the COD concentration of the sucralose mother liquor wastewater is still as high as 1500~ 3000mg / L, the concentration of ammonia nitrogen is as high as 130-150mg / L, which affects the ecological environment of the water body

Embodiment 1

[0021] In this embodiment, a method for treating sucralose mother liquor wastewater after biodegradation pretreatment, the steps are as follows:

[0022] (1) isolate and obtain bacillus group from soil;

[0023] Put 100mL of distilled water in a beaker, add 0.6g of yeast powder, 1.5g of peptone, 0.8g of sodium chloride, and 2.2g of agar in sequence to make an LB plate, use an inoculation loop to pick up 0.5mg of soil sample on a 15ml LB plate, and draw a line Separate and culture in a constant temperature incubator at a temperature of 37°C for 12 hours to obtain bacillus groups, such as Bacillus subtilis, Bacillus licheniformis, Bacillus natto, Bacillus cereus, etc.;

[0024] (2) The bacillus group is expanded and cultivated to obtain a pulpy high-density bacillus group

[0025] Take 1g of the above-mentioned bacillus group and inoculate it into TB medium made by adding 10g yeast powder, 6g peptone, 0.25g glycerol, and 9g phosphate to 500mL distilled water for expansion, main...

Embodiment 2

[0033] In this embodiment, a method for treating sucralose mother liquor wastewater after biodegradation pretreatment, the steps are as follows:

[0034] (1) isolate and obtain bacillus group from soil;

Abstract

The invention discloses a treatment method of biodegradable post-pretreatment sucralose mother liquor waste water. High-density bacillus flora is obtained by performing separating, purifying and culturing in soil, the post-pretreatment sucralose mother liquor waste water is added and step-by-step domestication is performed, organic pollutant and ammonia nitrogen are effectively decomposed, water quality is purified, and discharge water of which indexes are standard is obtained. According to the treatment method of the biodegradable post-pretreatment sucralose mother liquor waste water, bacterium cultivation operation is simple, the condition is mild, degradation of the post-pretreatment sucralose mother liquor waste water is fast and effective, environmental protection requirements can be met well, meanwhile the cost of waste water treatment is reduced, and a new path is provided for post-pretreatment sucralose mother liquor waste water treatment in industrial production.

Description

technical field [0001] The invention relates to the technical field of chemical production waste treatment, in particular to a treatment method for pretreated sucralose mother liquor wastewater in industrial production. Background technique [0002] At present, the basic methods of wastewater treatment in the prior art are physical, chemical, biological methods, or the combined use of these methods. Physical methods include precipitation, filtration, adsorption, extraction, etc. The equipment is simple and does not change the chemical form of pollutants, so it is limited to the removal of insoluble large particle pollutants in wastewater. Chemical methods include flocculation, sedimentation and chemical oxidation, etc., through electrical changes, cross-linking and bridging, etc., small particles dissolved in water can be separated into large particles by precipitation, and are usually suitable for wastewater pretreatment. The biological method uses microbial metabolism to ...
