How to deal with the sewage of the Chinese medicine decoction factory? 5

It depends on which province.

In fact, there is nothing to treat in the sewage treatment of ordinary decoction pieces, mainly sandy soil.

As for the water soaked in medicine, strictly speaking, it should be treated with reference to traditional Chinese medicine preparations, but it is required that the medicine is permeable and the active ingredients are not lost, so there are usually no sewage treatment facilities.

However, toxic decoction pieces require special treatment facilities.

The investment in sewage treatment in Anhui is less than 100,000 yuan, and more than 200,000 yuan.

The cost of pharmaceutical wastewater treatment depends on what facilities you have, you can go to the sewage treasure to ask.

If you are a construction unit, please find a professional environmental protection company to solve this problem.

If you are an environmental protection company, you can take a look at the "Technical Policy on Pollution Prevention and Control in the Pharmaceutical Industry (Draft for Comments)".

What kind of pieces do you produce, and what are the main pollutants in the wastewater discharged?

The wastewater treatment equipment is very easy to use, consider the water treatment of the sewer doctor.

The three-effect evaporation crystallizer designed by Kang Jinghui for a pharmaceutical company in Henan Province has a design treatment capacity of 400t d and a concentration ratio of up to 1:5, which is 4-5 times higher than that of a single-effect evaporator, and the evaporation treatment of pharmaceutical wastewater greatly reduces the cost of pharmaceutical wastewater treatment.

It depends on what you have in your wastewater.

Hello, glad to answer for you :

Pharmaceutical Wastewater Treatment Methods:

Catalytic oxidation:

Under the action of catalyst, the organic compounds in the medicinal wastewater can be oxidized and decomposed by strong oxidants, the organic compounds in the organic wastewater can be decomposed by the strong oxidants, the double bonds in the organic structure of the organic wastewater can be broken, the double bonds in the organic structure of the organic compounds can be oxidized into small molecules, and the small molecules can be further oxidized into carbon dioxide and water, the password is reduced, the password is increased, the password is increased, the password is increased, the biodegradability of the medicinal wastewater and the discharge of the medicinal wastewater can be achieved. The catalytic oxidation method can be used to treat pharmaceutical wastewater, which can overcome the shortcomings of the traditional biochemical treatment method for the treatment of pharmaceutical wastewater, and can effectively destroy the conjugated system of organic molecules, effectively destroy the conjugated system, remove the conjugated system, improve the biodegradability of the conjugated system, and improve the biodegradability of the conjugated system. In catalytic oxidation, the choice of catalyst and oxidant is key.

Internal electrolysis method: The principle of internal electrolysis method is to use iron and graphite components in iron filings to form the negative electrode and positive electrode of microelectrolysis, and use the filled sewage as the electrolyte, and in the acidic medium, the positive electrode generates new ecological hydrogen with strong reducibility, which can reduce heavy metal ions and organic pollutants. The negative electrode produces reduced iron ions. The product iron ions and ferrous ions are polymerized by hydrolysis to form hydroxide polymers, which exist in the form of colloids, which play the role of precipitation, flocculation and adsorption, and can form flocs together with pollutants to produce precipitation.

The application of internal electrolysis method can remove part of the color and part of the organic matter in the pharmaceutical wastewater, improve the biochemical treatment performance of the pharmaceutical wastewater, and increase the removal effect of biological treatment on the organic matter.

Anaerobic Biological Treatment:

Anaerobic biological treatment of pharmaceutical wastewater is the use of the metabolic process of anaerobic microorganisms to convert organic matter into inorganic matter without increasing oxygen, and convert it into trace amounts of cytoplasm, mainly biogas and water. This method is an efficient and energy-saving treatment technology for low-concentration organic pharmaceutical wastewater. For high-concentration organic pharmaceutical wastewater, it is an energy-saving treatment technology, and it is also an efficient treatment technology.

Coagulation and sedimentation method:

Coagulation and sedimentation filtration can effectively reduce the turbidity and color of water, and remove suspended solids and impurities. The coagulation process is a very complex physicochemical process, which is a complex physicochemical process, which is to mix a certain amount of coagulant into the pharmaceutical wastewater under certain pH value, temperature and other conditions, and react and precipitate the suspended water-soluble and supersaturated substances in the sewage through the suspended water-soluble and supersaturated substances suspended in the wastewater, so that the pharmaceutical wastewater can be clarified from turbidity to clarity.
