Problems solved by technology

However, its processing cost and reaction conditions are relatively high, and the operation is complicated.
Biological attenuation is mainly completed by microbial treatment, which has the advantage of low processing cost, but the biological attenuation method has problems such as long start-up time
At present, there is no effective treatment method for the toxic processing wastewater of aconitum medicinal materials, and it has not been effectively treated. Therefore, it is necessary to study an effective treatment method for the toxic processing wastewater of aconitum to completely solve the common technical problems in this industry.

Embodiment 1

[0023] Multi-stage combined flocculation device: including regulating tank 11, flocculation-settling tank 21, regulating tank 12, flocculation-settling tank 22, and flocculation-settling tank 23 connected in sequence; each regulating tank and flocculation-settling tank has a built-in agitator 3; the device also includes Hydrochloric acid storage tank 5, sodium polyacrylate storage tank 6, sodium hydroxide storage tank 7, polyacrylamide storage tank 8, polyaluminum chloride storage tank 9 and polyferric sulfate storage tank 10; said hydrochloric acid storage tank 5 uses belt The conduit of metering pump 4 is connected on the water inlet pipe of regulating tank 11; Described sodium polyacrylate reserve tank 6 is connected on the water inlet pipe of flocculation sedimentation tank 21 with the conduit of band metering pump 4; Described sodium hydroxide reserve tank 7 is connected on the water inlet pipe of regulating tank 12 with the conduit of band metering pump 4; On the water i...

Embodiment 2

[0032] The multi-stage combined flocculation device of Example 1 is used to selectively remove the toxic components of aconitine in the processing wastewater of Aconitum aconitum:

[0033] Step 1 Aconitum fruticosa processing waste water first enters regulating pond 11, adjusts metering pump 4 to extract the hydrochloric acid solution in the hydrochloric acid storage pond 5 and enters regulating pond 11 to adjust the wastewater pH value to 6, then enters in the flocculation sedimentation pond 21; the concentration of hydrochloric acid solution is 5mol / L;

[0034] Step 2 Adjust the metering pump 4 to extract the sodium polyacrylate solution in the sodium polyacrylate storage tank 6, so that the concentration of the sodium polyacrylate in the flocculation sedimentation tank 21 is 0.1mg / L, and under the action of the agitator 3, complete flocculation and precipitation Then enter the adjustment tank 12; the concentration of the sodium polyacrylate solution in the sodium polyacryla...

Abstract

The invention relates to a multistage combined flocculation device and a process for selectively removing aconitine type toxic ingredients from traditional Chinese medicine processing wastewater by using the same. The device comprises adjusting tanks and flocculation sedimentation tanks which are connected with one another in sequence, wherein a stirrer is arranged in each of the adjusting tanks and the flocculation sedimentation tanks. The device also comprises a hydrochloric acid storage tank, a sodium polyacrylate storage tank, a sodium hydroxide storage tank, a polyacrylamide storage tank, a polyaluminum chloride storage tank and a polymeric ferric sulfate storage tank which are connected with every adjusting tank or flocculation sedimentation tank. The process provided by the invention is particularly suitable for treating alkaloid in processing wastewater of aconite type traditional Chinese medicines including common monkshood mother root, kusnezoff monkshood root and the like, and can be used for realizing selective removal of alkaloids including hypaconitine, mesaconine, benzoyl mesaconine, benzoyl aconine, aconitine and the like; and moreover, a flocculant is easy to obtain and low in price, a constructed substance is small in volume, the cost is saved, the processing cycle is short, the operation is simple and convenient, the effect is obvious, and the stability is strong.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and in particular relates to a multi-stage combined flocculation device and a process for selectively removing aconitine-like toxic components in traditional Chinese medicine processing waste water. Background technique [0002] Aconitum Chinese medicinal materials are widely used in Chinese patent medicines, among which Chuanwu, Aconitum, Aconite and their processed products are most commonly used. According to statistics, the 2010 edition of the "Chinese Pharmacopoeia" and volumes 1-26 of the "Ministerial Standards of Traditional Chinese Medicine" contained more than 320 kinds of Chinese patent medicines containing Aconitum Aconitum, Aconitum Aconitum and Aconite. These medicinal materials are highly toxic in raw use and need to be processed before they can be used clinically, and have unique curative effects. Chuanconitum is the dry mother root of Aconitum carmichaelii Debx. of ...
