Problems solved by technology

[0003] During the production process of Pudilan Anti-inflammatory Oral Liquid, a large amount of semi-solid waste will be produced during the precipitation and storage stages. The existing treatment method is to add 50 to 60 times of water to dilute it in large quantities, and then transport it to the sewage treatment center for biochemical treatment. However, there are still a large amount of medicinal substances with antibacterial activity such as baicalin in the sediment, which can easily inhibit the growth of microorganisms in the process of biochemical treatment, and even produce toxicity to active microorganisms, resulting in a long period of biochemical treatment after dilution, which not only pollutes the environment but also causes resource pollution. waste

Embodiment 1

[0030] Example 1 Semi-solid waste produced in the production of Pudilan anti-inflammatory oral liquid

[0031] Pudilan Anti-inflammatory Oral Liquid is prepared from four herbs of dandelion, Radix Isatidis, Kudidin and Scutellaria baicalensis by the following method: 500 parts by weight of dandelion, 188 parts by weight of Banlangen, 125 parts by weight of Kudidin, add water and decocted twice , filtered for 1 hour each time, combined the filtrate, concentrated to a clear paste with a relative density of 1.13 to 1.15 (60 to 70 ° C), added ethanol to make the alcohol content 75% (volume percentage), placed for 48 hours, Filter (filter residue is waste 1), after the filtrate recovers ethanol, add water, place for 48 hours, filter (filter residue is waste 2), adjust the pH of the filtrate to 6.5 with 10% sodium hydroxide solution for subsequent use. Put 188 parts by weight of Scutellaria baicalensis into boiling water, decoct twice, first decoct for 10 minutes each time, adjust p...

Embodiment 2

[0034] The semi-solid waste in Example 1 is a high-concentration organic waste with complex composition and high pollutant content, and direct discharge will significantly affect the water quality. Pretreatment of the semi-solid waste: at 25°C, add 14 times its volume of water to the semi-solid waste, and use 1% (mass percent concentration) NaOH aqueous solution or 1% (mass percent concentration) of hydrochloric acid to adjust the pH to 6-7 and stir well. The water quality parameters after pretreatment are as follows: pH is 6.14, COD (chemical oxygen demand) is 124380mg / L, ammonia nitrogen content is 3070mg / L, turbidity is 1045NTU, conductivity is 7.43ms / cm, baicalin content is 16.70mg / mL, Wogonin 2.03mg / mL, cichoric acid 0.44mg / mL.

[0035] According to the method of the present invention, the pretreated semi-solid waste is treated as follows:

[0036] (1) The first ultrafiltration: the first ultrafiltration is dead end ultrafiltration, and the specific method is as follows...

Abstract

The invention provides a treatment method of pudilan anti-inflammatory oral liquid semi-solid waste, and relates to the field of traditional Chinese medicine production waste treatment. The method comprises the following steps: (1) diluting the semi-solid waste with water, adjusting the pH value to 6-7, and uniformly mixing; (2) carrying out primary ultrafiltration on the pretreated semi-solid waste; (3) carrying out second ultrafiltration on the permeate obtained by the first ultrafiltration; recovering baicalin from trapped fluid obtained by the second ultrafiltration treatment; (4) combining the trapped fluid after baicalin recovery, the permeate obtained by the second ultrafiltration treatment and the trapped fluid obtained by the first ultrafiltration treatment, adjusting the pH value to 7-9, and treating by using a membrane bioreactor; (5) carrying out nanofiltration treatment on effluent of the membrane bioreactor, and directly discharging permeate liquid; and (6) introducing trapped fluid obtained by nanofiltration treatment into the membrane bioreactor, and circulating the steps (4), (5) and (6). The treatment method disclosed by the invention can be used for simultaneously achieving the effects of recovering pharmacodynamic substances and discharging up to standard.

Description

technical field [0001] The invention relates to the technical field of waste treatment of traditional Chinese medicine production, in particular to a treatment method of semi-solid waste of Pudilan anti-inflammatory oral liquid. Background technique [0002] In recent years, with people's pursuit of natural products, the continuous progress of various separation technologies and refining technologies, the development and utilization of traditional Chinese medicine resources has entered a period of rapid development. develop. Emerging traditional Chinese medicine companies continue to emerge, and old-fashioned companies such as Yangzijiang Group, Kangyuan Pharmaceutical, Jichuan Pharmaceutical, etc. continue to expand their production scale. The rapid development of the traditional Chinese medicine industry has produced huge economic benefits. However, the waste generated after the extraction of a large number of Chinese herbal medicines brings urgent problems to manufactur...
