Problems solved by technology

[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, resulting in the discharge of printing and dyeing wastewater that cannot meet the standard after treatment.

Embodiment 1

[0026] The raw material components of a printing and dyeing wastewater treatment agent include: 60 parts of construction waste, 22 parts of soybean powder, 18 parts of wheat straw powder, 13 parts of kaolin, 10 parts of muddy soil, 15 parts of peat, waste paper scraps (maximum length less than 2mm ) 20 parts, clay 22 parts, aluminum chloride 18 parts, polyferric sulfate 10 parts, polysilicate flocculant (PSAA) 7 parts, polyphosphorus aluminum chloride (PPAC) 13 parts, flocculant PF1018 parts and water 100 parts , the parts are parts by mass.

[0027] The preparation method of above-mentioned printing and dyeing wastewater treatment agent comprises the steps:

[0028] 1) Pulverize the construction waste to a particle size of less than 1 mm to obtain construction waste powder;

[0029] 2) Heat up the construction waste powder obtained in step 1) to 200°C at a speed of 12°C / min, keep it warm for 33 minutes, then raise the temperature to 400°C at a speed of 38°C / min, keep it warm...

Embodiment 2

[0033] Basically the same as Example 1, the difference is: a printing and dyeing wastewater treatment agent, its raw material components include: 55 parts of construction waste, 20 parts of soybean powder, 15 parts of wheat straw powder, 10 parts of kaolin, and 8 parts of muddy soil , 12 parts of peat, 18 parts of waste paper (maximum length less than 2mm), 20 parts of clay, 15 parts of aluminum chloride, 8 parts of polyferric sulfate, 5 parts of polysilicate flocculant (PSAA), polyphosphorus aluminum chloride ( 10 parts of PPAC), 5 parts of flocculant PF101 and 100 parts of water, the parts are parts by mass.

Embodiment 3

[0035] Basically the same as Example 1, the difference is: a printing and dyeing wastewater treatment agent, its raw material components include: 65 parts of construction waste, 25 parts of soybean powder, 20 parts of wheat straw powder, 15 parts of kaolin, 13 parts of muddy soil , 18 parts of peat, 23 parts of waste paper (maximum length less than 2mm), 25 parts of clay, 20 parts of aluminum chloride, 13 parts of polyferric sulfate, 8 parts of polysilicate flocculant (PSAA), polyphosphorus aluminum chloride ( 15 parts of PPAC), 10 parts of flocculant PF101 and 100 parts of water, the parts are parts by mass.

[0036] Table 1 is the performance table of each embodiment gained product

[0037]

[0038] In each example, the usage amount of printing and dyeing wastewater purification agent is 0.5% of the wastewater quality.

Abstract

The invention discloses a printing and dyeing wastewater treating agent and a preparation method thereof. The printing and dyeing wastewater treating agent is prepared from, by mass, 55-65 parts of construction wastes, 20-25 parts of soybean meal, 15-20 parts of wheat straw powder, 10-15 parts of kaolin, 8-13 parts of mucky soil, 12-18 parts of peat, 18-23 parts of wastepaper scraps, 20-25 parts of clay, 15-20 parts of aluminum chloride and 100 parts of water. The printing and dyeing wastewater treating agent is prepared from the wastepaper scraps, the construction wastes and the like, the environmental problems caused by the wastepaper scraps and the construction wastes are solved radically, and moreover, the treating agent prepared by using the method has the efficient purification capacity, so that the removal rate of COCcr of textile printing and dyeing wastewater is up to 94.6%, the removal rate of the turbidity is up to 98.3%, and the removal rate of the chroma is up to 98.8%. The textile printing and dyeing wastewater can be discharged in an up-to-standard mode, and the preparation method is simple, easy to operate and high in practicability.

Description

technical field [0001] The invention relates to a printing and dyeing wastewater treatment agent 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, resulting in the discharge of pr...
