Embodiment 1

[0034] A preparation method of a textile wastewater treatment agent, comprising the following steps:

[0035] (a) each component is weighed according to the proportion by weight described in the formula, and 50 parts of modified red mud, 10 parts of diatomite and 8 parts of activated carbon are reacted at 60° C. and 400 r / min for 2 h, and then cooled for later use;

[0036] (b) subsequently adding 30 parts of flocculant, 8 parts of boric acid and 27 parts of modified starch into the product obtained in step (a), adding it into the mixer, controlling the temperature to be 50°C, stirring for 30min, and obtaining a wastewater treatment agent after the stirring.

[0037] Wherein, the preparation method of described modified red mud comprises the following steps:

[0038] (1) 20 parts of red mud are pulverized and then sieved, and the impurities of crushed ore chips are removed to obtain the red mud with impurity removal, then the red mud is added to 200 parts of 10% hydrogen perox...

Embodiment 2

[0043] A preparation method of a textile wastewater treatment agent, comprising the following steps:

[0044] (a) each component is weighed according to the proportion by weight described in the formula, and 40 parts of modified red mud, 7 parts of diatomite and 10 parts of activated carbon are reacted at 50° C. and 300 r / min for 3 h, and then cooled for later use;

[0045] (b) subsequently adding 20 parts of flocculant, 10 parts of boric acid and 20 parts of modified starch, adding the product obtained in step (a), adding it into the mixer, controlling the temperature to be 40°C, stirring for 60min, and obtaining a wastewater treatment agent after stirring.

[0046] Wherein, the preparation method of described modified red mud comprises the following steps:

[0047] (1) 15 parts of red mud are pulverized and then sieved, and the impurities of crushed ore chips are removed to obtain the red mud with impurity removal, then the red mud is added to 200 parts of 5% hydrogen peroxi...

Embodiment 3

[0052] A preparation method of a textile wastewater treatment agent, comprising the following steps:

[0053] (a) each component is weighed according to the proportion by weight described in the formula, and 45 parts of modified red mud, 10 parts of diatomite and 10 parts of activated carbon are reacted at 55° C. and 400 r / min for 3 h, and are used after cooling;

[0054] (b) subsequently adding 25 parts of flocculant, 7 parts of boric acid and 23 parts of modified starch, adding the product obtained in step (a), adding into the mixer, controlling the temperature to be 45°C, stirring for 50min, and obtaining a waste water treatment agent after stirring.

[0055] Wherein, the preparation method of described modified red mud comprises the following steps:

[0056] (1) 20 parts of red mud are pulverized and then sieved, and the impurities of crushed ore chips are removed to obtain the red mud with impurity removal, then the red mud is added to 200 parts of 7% hydrogen peroxide an...

Abstract

The invention discloses a textile wastewater treatment agent and a preparation method thereof, and the textile wastewater treatment agent is prepared from the following raw materials in parts by weight: 40-60 parts of modified red mud, 20-35 parts of a flocculant, 7-13 parts of diatomite, 5-10 parts of activated carbon, 5-10 parts of boric acid and 20-30 parts of modified starch. The red mud and the starch are modified, so that the problems of complex components, high content of organic substances and harmful substances, deep chromaticity, serious harm to water and the like in the textile wastewater are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a textile wastewater treatment agent and a preparation method thereof. Background technique [0002] The textile printing and dyeing industry, as one of the important private production industries and international competitive advantage industries in China, plays an extremely important role in promoting the development of the market economy and increasing the employment rate. Although the textile printing and dyeing industry has invested a lot of manpower and material resources in energy saving and emission reduction, because the printing and dyeing industry has the characteristics of large energy consumption, large water consumption, and large wastewater discharge, with the continuous development of social economy, printing and dyeing wastewater accounts for the national industrial wastewater discharge. The total amount continues to increase and has becom...
