Problems solved by technology

Among them, biochemical method is the most effective method for treating traditional Chinese medicine wastewater, because traditional Chinese medicine wastewater contains a large amount of polymer refractory organic matter, biochemical method can effectively treat and decompose a large amount of polymer refractory organic matter in traditional Chinese medicine wastewater, but in practice During production, since the components of traditional Chinese medicine usually contain various organic acids, some organic acids in the traditional Chinese medicine enter the wastewater during the production of traditional Chinese medicine, making the wastewater of traditional Chinese medicine acidic, and it is easy to form a relatively stable organic acid buffer system, and the acidic environment is not suitable The growth of microorganisms in the later anaerobic treatment and aerobic treatment, and the organic acid buffer system has a stronger inhibitory effect on the microorganisms in the biochemical system due to its strong stability, so the treatment efficiency of the organic acid buffer system on the biochemical system Increase has a greater negative impact

Embodiment 1

[0031] The mixed production wastewater of a traditional Chinese medicine pharmaceutical factory in Chengdu, Sichuan, mainly consists of seven categories: traditional Chinese medicine production wastewater, bottle washing, rubber stopper washing wastewater, resin regeneration wastewater, machine repair wastewater, domestic wastewater, quality inspection wastewater, and residual liquid after ethanol distillation and recovery. The composition of wastewater, the average CODCr value of wastewater is 18150mg / L, the pH value is 4.6, and the average value of ammonia nitrogen is 1100mg / L. Use the graded circulation device to adjust the pH value of the traditional Chinese medicine wastewater, pump part of the water in the adjustment pool to the second tank of the graded circulation reactor with the reaction device, turn on the agitator, and add slaked lime to adjust the pH to about 10 . The other part of the water in the adjustment tank is sent to the first tank of the graded circulatio...

Embodiment 2

[0033]The mixed production wastewater of a traditional Chinese medicine pharmaceutical factory in Sichuan is used, which is mainly composed of pharmaceutical raw material washing water, raw drug decoction and extraction process residue, tank (bottle) washing water, ground flushing water, boiler room drainage and factory domestic sewage, etc. The CODCr is 11000mg / L, the pH value is 4.9, and the ammonia nitrogen content is 300mg / L. Use a graded circulation device to adjust the pH value of traditional Chinese medicine wastewater, pump part of the water in the adjustment pool to the second tank of the graded circulation reactor with a reaction device, turn on the agitator, and add sodium hydroxide to adjust the pH to 10 or so. The other part of the water in the adjustment tank is sent to the first tank of the graded circulation reactor at the same time with the circulation pump of the reaction device, and the water flow enters the lower part of the first tank in a tangential flow,...

Embodiment 3

[0035] The mixed production wastewater from a traditional Chinese medicine pharmaceutical factory in Sichuan is mainly composed of extraction tank cleaning wastewater, raw material cleaning and soaking wastewater, and workshop floor flushing water. The CODCr in the water is 8000mg / L, the pH value is 6, and the ammonia nitrogen content is 58mg / L. Use the graded circulation device to adjust the pH value of the traditional Chinese medicine wastewater, pump part of the water in the adjustment pool to the second tank of the graded circulation reactor with the reaction device, turn on the agitator, and add slaked lime to adjust the pH to about 10 . The other part of the water in the adjustment tank is sent to the first tank of the graded circulation reactor at the same time with the circulation pump of the reaction device, and the water flow enters the lower part of the first tank in a tangential flow, so that the water in the first tank is rotated , the outlet water from the second...

Abstract

The invention discloses a traditional Chinese medicine wastewater treatment process. The process has the following beneficial effects: after the traditional Chinese medicine wastewater is pretreated and the pH value of the traditional Chinese medicine wastewater is adjusted to be 8-9, the traditional Chinese medicine wastewater is subjected to anaerobic treatment, biochemical reflux treatment and filter and drain treatment; by combining the treatment methods, the traditional Chinese medicine wastewater can be effectively treated, so that the effluent of the treated traditional Chinese medicine wastewater can reach the primary standard (GB8978-1996); and the process has good environmental and economic benefits.

Description

technical field [0001] The invention relates to a wastewater treatment process, in particular to a traditional Chinese medicine wastewater treatment process. 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 water-soluble pollutants are sugars (mainly polysaccharides), prot...
