Problems solved by technology

[0003] The discharge of printing and dyeing wastewater is large, and with the rapid development of the dye industry, the variety and quantity of fuels are increasing day by day, the emergence of a large number of chemical fiber products, and the adoption of new chemical pulp, dyeing materials and finishing agents have greatly changed the printing and dyeing industry. The nature of wastewater increases the difficulty of its treatment, and its COD concentration also rises from hundreds of mg / L to 2000-3000 mg / L, thus reducing the COD removal rate of the original biological treatment device from 70% to about 50%. Even lower, it is far from meeting the requirements of the first-level B standard of the "Urban Sewage Treatment Plant Pollutant Discharge Standard", and needs to be remodeled

Embodiment 1

[0021] A purification agent for printing and dyeing wastewater, in parts by weight, comprising the following components: 11 parts of polyacrylamide, 13 parts of tourmaline powder, 6 parts of konjac glucomannan, 10 parts of durian extract, 5 parts of mineral powder, 3 parts of odorant, 0.5 parts of oxidant;

[0022] The preparation method of the durian extract is as follows: cut off the outer shell of fresh durian at 15° C., take out the fresh and intact pulp without decay, and remove the core from the pulp to obtain the durian puree. Place the durian puree In the vacuum deodorizer, while stirring, feed in food grade CO with a purity of 99.9% at 5°C 2 , Extract at the same time to remove the air-conditioning carrying peculiar smell, the pressure in the deodorizer is 0.5Mpa, the temperature is 5℃, the extraction time is 30min, the stirring rate is 55 revolutions / min, and the specific low molecular odor of hydrogen sulfide in the durian fruit paste is removed Flavor substances, reta...

Embodiment 2

[0029] A purification agent for printing and dyeing wastewater, in parts by weight, comprising the following components: 25 parts of polyacrylamide, 18 parts of tourmaline powder, 12 parts of konjac glucomannan, 25 parts of durian extract, 10 parts of mineral powder, 6 parts of odorant, 1 part of oxidant;

[0030] The preparation method of the durian extract is as follows: cut off the shell of fresh durian at 20° C., take out the fresh and intact pulp without decay, and remove the core from the pulp to obtain durian pulp, and place the durian pulp in In the vacuum deodorizer, while stirring, pass in food grade CO with a purity of 99.9% at 10°C 2 , Extraction at the same time to eliminate the cold air carrying peculiar smell gas, the volume utilization rate of the deodorizer during the deodorization process is 80-90%, the internal pressure of the deodorizer is 1Mpa, the temperature is 15℃, the extraction time is 50min, and the stirring rate is 105 revolutions / min. The hydrogen sul...

Embodiment 3

[0037] A purification agent for printing and dyeing wastewater, in parts by weight, comprising the following components: 19 parts of polyacrylamide, 16 parts of tourmaline powder, 8 parts of konjac glucomannan, 22 parts of durian extract, 8 parts of mineral powder, 4 parts of odorant, 0.7 parts of oxidant;

[0038] The preparation method of the durian extract is as follows: cut off the shell of fresh durian at 17° C., take out the fresh and intact pulp without decay, and remove the core from the pulp to obtain durian pulp, and place the durian pulp in In the vacuum deodorizer, while stirring, feed in food grade CO with a purity of 99.9% at 6°C 2 At the same time, extraction is carried out to eliminate the cold air carrying peculiar smell gas. During the deodorization process, the volume utilization rate of the deodorizer is 80-90%, the internal pressure of the deodorizer is 0.7Mpa, the temperature is 8℃, the extraction time is 40min, the stirring rate is 70 revolutions / min, In ad...

Abstract

The invention discloses a printing and dyeing wastewater purification agent and a preparation method thereof. The printing and dyeing wastewater purification agent comprises, by weight, 11-25 parts ofpolyacrylamide, 13-18 parts of tourmaline powder, 6-12 parts of konjac glucomannan, 10-25 parts of durian extract, 5-10 parts of mineral powder, 3-6 parts of a deodorant and 0.5-1 part of an oxidant.The mineral powder comprises, by weight, 5-8 parts of peridot powder, 2-6 parts of humic acid, 2-5 parts of granite powder, 1-3 parts of alkaline feldspar powder, 2-10 parts of basalt powder, 1-3 parts of quartzite powder and 2-5 parts of spodumene powder. The printing and dyeing wastewater purification agent can effectively reduce CODCr, ammonia nitrogen and SS content of waste water dischargedby a printing and dyeing plant. The treated water can satisfy the national emission standards. The preparation method is simple, is suitable for industrial production and has a high economic value.

Description

Technical field [0001] The invention relates to the technical field of sewage purification, in particular to a purifying agent for printing and dyeing wastewater and a preparation method thereof. Background technique [0002] Printing and dyeing wastewater is wastewater discharged from printing and dyeing plants that process cotton, linen, chemical fiber and their blended products. Printing and dyeing wastewater has a relatively large amount of water, and each ton of textiles in the printing and dyeing process consumes 100-200 tons of water, of which 80-90% becomes wastewater. [0003] The discharge of printing and dyeing wastewater is large, and with the rapid development of the dye industry, the variety and quantity of fuels are increasing day by day, the emergence of a large number of chemical fiber products, the adoption of new chemical slurries, dyeing chemicals and finishing agents have greatly changed the printing and dyeing industry. The nature of wastewater has increased ...
