preparation example Construction

[0042] In addition, the present invention also provides a method for preparing a treatment agent for textile wastewater, using the following steps:

[0043] 1) Prepare a composite material with a nano-microspherical structure as a carrier;

[0044] 2) Bacillus subtilis and activated sludge microorganisms that were separated, purified and cultured for several days were collected, and the mild method of comprehensive freeze-thawing and ultrasonic crushing was used to obtain the lysed active product of the bacteria, which was washed with pure water for later use, and the preparation process was mild and kept at low temperature;

[0045] 3) Dispersing the composite material with nano-microspherical structure obtained in step 1) into a phosphate buffer solution with a pH of 6-9 to form a low-viscosity solution, wherein the amount of the composite material is 0.2-2% of the phosphate buffer solution , and then add the lysate obtained in step 2), the amount of the lysate added is 0.1-...

Embodiment 1

[0068] A treatment agent for textile wastewater, comprising nanozyme SECMGA, and activator WRLL and activator BOJF for activating nanozyme SECMGA, the activator WRLL adopts dihydrogen phosphate, and the activator BOJF adopts ammonium Salt;

[0069] The treatment agent is prepared through the following steps:

[0070] 1) Using the existing patent "a composite material and its preparation method and its application in sewage biochemical treatment" (application number is CN201710784101.6), the composite material with nano-microspherical structure is prepared as the carrier of the present invention; for example, using

[0071] a) 100 grams of sodium silicate, 30 grams of clay (purchased from Qingdao Wanhong Mining Co., Ltd.), 30 grams of iron oxide (Fe 2 o 3 ), 30 grams of alumina (Al 2 o 3 ), 10ml of concentrated hydrochloric acid (commercially available) were mixed evenly, and the airtight reaction was carried out at 120°C for 6 hours;

[0072] b) Mix the reaction product i...

Embodiment 2

[0080] A preparation method for a treatment agent for textile wastewater, step 1), step 2) are the same as the steps in Example 1;

[0081] In step 3), the composite material with nano-microspherical structure obtained in step 1) is dispersed into a phosphate buffer solution with a pH of 8 to form a low-viscosity solution, wherein the amount of the composite material is 1% of the phosphate buffer solution , and then add the lysate obtained in step 2), the amount of the lysate added is 5% of the phosphate buffer, stirred at room temperature for 2 hours, passed through a 300-mesh net after low-frequency ultrasound, and packed into a specific water treatment device after measuring the encapsulation efficiency Inside.

Abstract

The invention discloses a treatment agent for textile waste water, a preparation method and a treatment process thereof, belonging to the technical field of sewage treatment, including nano-enzyme SECMGA, and activator WRLL and activator BOJF for activating nano-enzyme SECMGA; the nano-enzyme The enzyme SECMGA is activated before use, and the activator WRLL and the activator BOJF are respectively the required agents for activating the original ecological SECMGA; the activator WRLL is also the required agent for activating the transition state SECMGA to the activated state SECMGA . The treating agent of the invention has simple technical process for textile wastewater treatment, low equipment investment, automatic control, flexible operation and convenient management, and is suitable for large-scale use in wastewater treatment workshops of textile enterprises.

Description

technical field [0001] The invention relates to a treatment agent for textile wastewater, a preparation method and a treatment process thereof, and belongs to the technical field of sewage treatment. Background technique [0002] In recent years, with the rapid development of the textile industry, the treatment of a large amount of sewage with complex toxic substances has become an environmental protection problem that needs to be solved urgently. The textile industry includes textile, printing and dyeing, clothing and other industries. The wastewater is characterized by high concentration of organic pollutants in the components, poor biodegradability, deep color, etc., and it is difficult to treat. [0003] The water quality of textile industrial wastewater varies greatly, and the raw materials, processes, dyes and chemicals change a lot, which means that each situation is different, which brings certain difficulties to its end treatment, and also determines whether textile...
