Problems solved by technology

[0003] The traditional Chinese medicine treatment process needs to adjust the pH value of the wastewater to 8-9 to ensure the normal operation of the sewage treatment process. The anaerobic technology used in the traditional process is immature, and there are low impact load resistance and acid-base buffering during operation. Poor, low sludge load, floor space and other disadvantages

Embodiment

[0032] Such as figure 1 As shown, the wastewater generated in the process of traditional Chinese medicine pharmaceuticals comes from washing water, pot washing water, medicinal water, preparation water and other water.

[0033] Pretreatment: The sewage is input into the waste storage tank through different pipelines, passes through the grille and the wool filter successively, and enters the regulating tank by gravity, and the water quality and quantity are homogenized, and then enters the coagulation tank and the sand filter tank to remove suspended impurities;

[0034] Biochemical treatment: the water filtered by the sand filter enters the hydrolysis oxidation tank through the lifting pump, and the macromolecular organic substances are degraded into small molecular organic substances by hydrolysis and acidification to improve the biodegradability of the wastewater; it enters the SBR reaction tank through the lifting pump, The SBR pool is operated in a staggered intermittent m...

Abstract

The invention discloses a traditional wastewater processing system and technology, and belongs to the technical field of pharmacy wastewater processing. The system comprises a pretreatment system, a bio-processing system, an advanced processing system, and a sludge processing system, and the bio-processing system is the core processing system and comprises a hydrolysis-acidification tank and an SBR tank, wherein the SBR tank adopts an intermittent operation mode and has a strong performance on resisting impact. The adaptability to the introduced water quality change is greatly improved by the provided technology, the processed wastewater is clear and meets the national I-grade standards, the sludge can be subjected to a compost treatment to produce fertilizer, and the wastes are converted into valuable resource. The technology has the advantages of low cost and simple and easy operation, can save cost for entrepreneurs, and protects the local environment.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical wastewater treatment, and in particular relates to a traditional Chinese medicine wastewater treatment system and process. Background technique [0002] Pollutants in production wastewater can be roughly divided into two types: water-soluble and water-insoluble. Water-soluble pollutants are mainly organic substances such as tannins, alkaloids, organic acids, sugars, anthraquinones, and starches, as well as non-toxic pigments introduced in the preparation process and polymer substances discharged from tablet workshops. Water-insoluble pollutants mainly come from cleaning, decocting and other processes, mainly silt and plant suspended matter. Because it is a traditional Chinese medicine pharmaceutical enterprise, the toxic substances in its production wastewater are less, and the COD is lower than that of western medicine pharmaceutical wastewater. Among them, the wastewater from the washing...
