Embodiment 1

[0028] A preparation method of a traditional Chinese medicine wastewater treatment agent based on microorganisms, comprising the following steps:

[0029] A. Add deionized water to the mixer, adjust the speed to 380rpm,

[0030] B. Slowly add citric acid and ethylene glycol diglycidyl ether into the mixer, and the adding time is controlled at 18 minutes;

[0031] C. Adjust the rotation speed to 200rpm, slowly add polyaluminum iron silicate into the mixer within 12min, and stir for 45min;

[0032] D. Add modified cornstarch slowly, and control the maximum reaction temperature to be 53°C. When the reaction temperature rises rapidly, slow down the feeding speed until the feeding is completed, and the whole reaction process is completed within 35 minutes;

[0033] E, continue to slowly drop in sodium acetate, control the highest reaction temperature to be 53°C, and the entire reaction process is completed within 16 minutes;

[0034] F. Lower the temperature to normal temperature...

Abstract

The invention discloses a preparation method of a microorganism-based traditional Chinese medicine wastewater treatment agent. The method comprises the following steps: adding water to an agitator, slowly adding citric acid and ethylene glycol diglycidyl ether; adding polyaluminum ferric silicate, then slowly adding modified corn starch, controlling the highest reaction temperature to be 52-55 DEGC, reacting for 30-40 minutes, then adding sodium acetate, continuously reacting, finally cooling to room temperature, slowly adding attapulgite, a complex microbial inoculant and chitosan, uniformlystirring, concentrating, and carrying out spray drying, so as to obtain the product. The microorganism-based traditional Chinese medicine wastewater treatment agent disclosed by the invention has a very good treatment effect on total nitrogen, total phosphorus and organic matters in traditional Chinese medicine wastewater and suspended solids in water. Compared with corn starch, the polylactic acid modified corn starch has the advantages that the treatment effect is remarkably enhanced; by adopting the method to treat the traditional Chinese medicine wastewater, the speed is remarkably increased, and the treatment process can be generally completed within 60 minutes under the condition of introducing air.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment agents, in particular to a preparation method of a microorganism-based traditional Chinese medicine wastewater treatment agent. Background technique [0002] Traditional Chinese medicine wastewater mainly comes from the production workshop, which is produced in the process of washing and cooking medicinal materials, washing, and preparation. Traditional Chinese medicine wastewater includes raw drug washing water in the production process, raw drug juice residue, sewage generated in unit operations such as filtration, distillation, and extraction, production equipment washing, floor flushing water, steam condensate water, and ion exchange resin acid-base treatment Neutralizing water for solutions, etc. [0003] Pollutants in traditional Chinese medicine wastewater can be roughly divided into two categories: one is water-soluble, and the other is insoluble. The main components of wate...
