Problems solved by technology

[0006] In summary, the process of producing promestrine with estradiol as the starting material is the mainstream process at this stage, but the treatment of hormone-containing wastewater generated in the existing process is still a problem that plagues the production of enterprises, and it has not been effective The treatment plan is not only irresponsible to the enterprise but also irresponsible to the environment, so it is necessary to study a convenient, simple, economical and effective treatment plan for promestriene wastewater

Embodiment 1

[0040] (1) Take respectively 500g of the waste liquid of the first step and the waste liquid of the second step of promestriene synthesis wastewater, put them into a 2000ml four-necked bottle, and distill under reduced pressure at a bottom temperature of 45°C and a vacuum of -0.095Mpa to nothing Liquid comes out.

[0041] (2) 500g water is added in remaining liquid and is cooled to below 20 ℃ and begins to drip the sodium hypochlorite aqueous solution of 8wt% concentration slowly, test pH value in the dropping process, stop dripping when treating that pH value reaches 7.2. Heat the system to 60°C and stir for 3 hours to form a uniform mixed solution. The pH value of the retest is 7.4. If the pH value of the retest is still between 6-9, it is considered qualified. After passing the test, proceed to the next step.

[0042] (3) Turn off the heating, lower the temperature to about 20°C, add 10 g of anaerobic microbial community composed of yeast and bifidobacteria with a mass rati...

Embodiment 2

[0048] (1) Take 10kg of the waste liquid of the first step and the waste liquid of the second step of promestriene synthesis wastewater respectively, put them into a 50L glass kettle, and distill under reduced pressure at a bottom temperature of 60°C and a vacuum of -0.090Mpa until there is no liquid flow out.

[0049] (2) Add 10kg of water in the remaining liquid and cool down to below 20°C and start to slowly drip the sodium hypochlorite aqueous solution of 10wt% concentration, test the pH value during the dropping process, and stop the dripping when the pH value reaches 8.4. Heat the system to 60°C and stir for 5 hours to form a uniform mixed solution. Retest the pH value to 8.0. If the retested pH value is still between 6 and 9, it is considered qualified. After passing the test, proceed to the next step.

[0050] (3) Turn off the heating, cool down to about 20°C, add 1 kg of anaerobic microbial community composed of yeast and bifidobacteria with a mass ratio of 1:1, and a...

Embodiment 3

[0056] (1) Take 1500kg of the waste liquid of the first step and the waste liquid of the second step of promestriene synthesis wastewater respectively, put them into a 5000L enamel kettle, and distill under reduced pressure at a bottom temperature of 65°C and a vacuum of -0.098Mpa until there is no liquid flow out.

[0057] (2) add 3000kg water in the remaining liquid and cool down to below 20 ℃ and begin to slowly add the sodium hypochlorite aqueous solution of 12wt% concentration, test the pH value in the dropping process, stop dripping when the pH value reaches 7.6. Heat the system to 65°C and stir for 4 hours to form a uniform mixed solution. Retest the pH value to 7.2. If the retested pH value is still between 6-9, it is considered qualified. After passing the test, proceed to the next step.

[0058] (3) Turn off the heating, cool down to about 25°C, add 300kg of anaerobic microbial community composed of yeast and bifidobacteria with a mass ratio of 1:1, and add a mixed e...

Abstract

The invention belongs to the technical field of wastewater treatment, and particularly relates to a treatment method of wastewater produced in promestriene synthesis. According to the method, sodium hypochlorite is firstly added into the promestriene synthesis wastewater for pretreatment, and then microorganisms and enzymes are added for degradation treatment to obtain a sodium chloride solid andwater; sodium hypochlorite is directly used for realizing simultaneous strong alkali destroy and oxidization; meanwhile, a new scheme for improving hormone-containing wastewater treatment via degradation and consumption by microbial populations in an enzyme catalysis manner is also discovered, and the scheme is much more advanced than a conventional scheme in which wastewater is not qualified andcannot be discharged due to incomplete biodegradation. According to detection results, finally-generated water reaches national emission standards, and an inorganic salt can be recycled.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a treatment method for promestriene synthesis wastewater. Background technique [0002] Promestriene belongs to the class of steroidal estrogen drugs, and has the repairing effect of cervical and vaginal mucosa damage. In addition, proestrene can also promote the production of local lactic acid bacteria in the vagina, which is beneficial to maintain the local acidic environment of the vagina and prevent bacterial invasion; it also has the effect of promoting the healing of wounds in the vulva and vagina after surgery and physical therapy. Proestrene is mainly used for the replacement therapy of menopause, menopause and estrogen deficiency caused by estrogen deficiency in the genitourinary system, dryness of the urogenital system, itching, pain, dyspareunia, and atrophic vulvovaginitis. Proestrene is a topical vaginal drug with little absorption, so it wi...
