Application of sludge dewatering press in chemical pharmaceutical industry

Introduction to sewage in pharmaceutical industry:

The rapid development of the pharmaceutical industry has also brought a big problem. How to deal with sewage and pollution? The wastewater from pharmaceutical industry has become one of the sources of water pollution.

Characteristics of wastewater from pharmaceutical industry:

The water pollution in the pharmaceutical industry mainly comes from the washing water and flushing wastewater in the production of antibiotics, Chinese patent drugs, synthetic drugs and various preparations. It is relatively difficult to handle because of its complex composition, high salinity, deep color, high toxicity and high organic content. Although there are a lot of water pollution treatment equipment for the pharmaceutical industry on the market, most of the treated water resources are mixed in quality.

Sludge dewatering press is good at wastewater treatment in the pharmaceutical industry, saving resources, electricity, water and labor. It is more convenient, fast and easy to maintain than traditional treatment methods. The equipment is not easy to be blocked and has a unique structure, requiring no large amount of water to wash; It can operate continuously for 24 hours without guard; No secondary pollution such as noise, water and odor; It has unique phosphorus removal function; The core components have been treated by special process and are durable. All materials of the body are made of stainless steel, which is solid and beautiful, and has strong corrosion resistance. It is more suitable for the treatment of wastewater containing residual corrosive substances in the drug production process.

Complexity of wastewater treatment in chemical pharmaceutical industry:

The production process of chemical pharmacy consists of the production of APIs and pharmaceutical preparations. APIs are obtained through chemical synthesis process and separation and purification from medicinal plants. The production process has the following characteristics: long production process and complex process; There are many kinds of raw and auxiliary materials, the quality standards of intermediates and products in the production process are high, and the quality of raw materials and intermediates is strictly controlled; The net yield of materials is low, with more by-products and more three wastes. The wastewater produced by chemical pharmaceutical enterprises in industrial production is one of the industrial wastewater with serious pollution and difficult treatment in China. It has the characteristics of high content of organic matter and inorganic salt, low and fluctuating ratio of BOD5 and CODcr, poor biodegradability, intermittent discharge, and large fluctuation of water volume.

Advantages of sludge dewatering press in treating chemical pharmaceutical wastewater:

Sludge dewatering press, as a new type of sludge dewatering equipment, uses flocculant to absorb sludge impurities. It is compressed into shape through the screw extrusion principle, which can effectively absorb toxic and harmful substances in sludge and improve the performance of reaching the standard of wastewater. The equipment is made of 304 stainless steel, which has corrosion resistance, stability, and long service life. During operation, it can be unattended, reduce labor, and avoid contact with toxic and harmful substances, Compared with the traditional filter press, there are fewer vulnerable parts, no need to replace the filter cloth, low energy consumption and low use cost.
