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 the first regulating tank 11, the first flocculation-settling tank 21, the second regulating tank 12, the second flocculation-settling tank 22, and the third flocculation-settling tank 23 connected in sequence; each regulating tank and flocculation-settling tank All have a built-in agitator 3; the device also includes a hydrochloric acid storage tank 5, a sodium polyacrylate storage tank 6, a sodium hydroxide storage tank 7, a polyacrylamide storage tank 8, a polyaluminum chloride storage tank 9 and a polyferric sulfate storage tank 10 The hydrochloric acid storage tank 5 is connected to the water inlet pipe of the first regulating tank 11 with a conduit with a metering pump 4; the sodium polyacrylate storage tank 6 is connected with the first flocculation-settling tank with a conduit with a metering pump 4 21 on the water inlet pipe; the sodium hydroxide reserve tank 7 is connected on the water inlet pipe of the second...

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 Aconitum processing wastewater first enters the first regulating tank 11, adjusts the metering pump 4 to extract the hydrochloric acid solution in the hydrochloric acid storage tank 5, enters the first regulating tank 11, adjusts the pH value of the wastewater to 6, and then enters the first flocculation and sedimentation tank 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 first flocculation sedimentation tank 21 is 0.1mg / L, and under the action of the agitator 3, complete the flocculation Enter the second regulating tank 12 after precipitation; The concentration of the so...

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. Chuanwu is the dry mother root of Aconitum carmichaelii Debx. of Ranun...
