Embodiment 1

[0022] A high-efficiency and fast purifying agent for printing and dyeing wastewater, its raw material components include: 22 parts of activated carbon, 18 parts of diatomite, 28 parts of mica powder, 11 parts of alumina, 12 parts of quartz sand, 18 parts of polyaluminum chloride, polyacrylamide 20 parts, 11 parts of magnesium oxide and 35 parts of polyamide resin, the said parts are parts by mass.

[0023] The preparation method of the above-mentioned high-efficiency and fast purifying agent for printing and dyeing wastewater is to mix activated carbon, diatomite, mica powder, alumina, quartz sand, polyaluminum chloride, polyacrylamide, magnesium oxide and polyamide resin under the condition of 90 ° C. After drying for 6 hours, crush it to 200 mesh.

[0024] The amount of high-efficiency and fast purifying agent used for printing and dyeing wastewater is 1% of the wastewater quality.

Embodiment 2

[0026] It is basically the same as Example 1, the difference is: a high-efficiency and rapid purification agent for printing and dyeing wastewater, its raw material components include: 20 parts of activated carbon, 15 parts of diatomaceous earth, 25 parts of mica powder, 8 parts of alumina, 10 parts of quartz sand parts, 15 parts of polyaluminum chloride, 18 parts of polyacrylamide, 8 parts of magnesium oxide and 30 parts of polyamide resin, and the said parts are parts by mass.

Embodiment 3

[0028] It is basically the same as Example 1, the difference is: a high-efficiency and rapid purification agent for printing and dyeing wastewater, its raw material components include: 25 parts of activated carbon, 20 parts of diatomaceous earth, 30 parts of mica powder, 15 parts of alumina, 15 parts of quartz sand 20 parts, 20 parts of polyaluminum chloride, 23 parts of polyacrylamide, 15 parts of magnesium oxide and 40 parts of polyamide resin, the said parts are parts by mass.

[0029] Table 1 is the performance table of each embodiment gained product

Abstract

The invention discloses a printing and dyeing wastewater efficient and quick purifying agent. The purifying agent is prepared from, by weight, 20-25 parts of activated carbon, 15-20 parts of diatomite, 25-30 parts of mica powder, 8-15 parts of aluminum oxide and 30-40 parts of polyamide resin. The printing and dyeing wastewater efficient and quick purifying agent has an efficient purifying ability, the removal rate of COCcr in printing and dyeing wastewater is as high as 90%, the turbidity removal rate is as high as 95%, and the chroma removal rate can be 95%.

Description

technical field [0001] The invention relates to a high-efficiency and fast purifying agent for printing and dyeing wastewater and a preparation method thereof, belonging to the field of sewage purification. Background technique [0002] Water is an important natural resource for the survival and development of human society. With the rapid development of industry, water pollution is constantly escalating, and the wastewater produced by printing and dyeing is an important source of water pollution. At present, the treatment of printing and dyeing wastewater mainly includes physical methods, biological methods and chemical methods, among which chemical methods are widely used. [0003] my country's printing and dyeing industry is developing rapidly, the discharge of printing and dyeing wastewater is large, and the composition is complex and difficult to treat. However, the efficiency of the existing chemical treatment agents for printing and dyeing wastewater is still low, res...
