"Micro-electrolysis wastewater treatment technology" is especially for the treatment of organic matter concentration, high toxicity, high chroma and difficult biochemical wastewater, which can greatly reduce the color and COD of wastewater, and increase the B/C ratio to improve the biodegradability of wastewater. Can be widely used in printing and dyeing, chemical, electroplating, pulp and paper, pharmaceutical, scouring, pesticides, alcohol and other industrial wastewater treatment and treatment water reuse projects.
Puyinworun Environmental Protection Co., Ltd. is a professional manufacturer and supplier specializing in the production of micro-electrolysis and fillers (iron-carbon/filler). It is a micro-electrolysis and filler for micro-electrolysis wastewater treatment technology. The unique advantages of our company's new filler in 2013: no consolidation, low loss, large surface area, high strength, decolorization, COD reduction... excellent sewage treatment! Filler products are sold to all parts of the country
The experiment and application of iron-carbon micro-electrolysis process and oxidation technology have a long history. Generally, the iron-carbon micro-electrolysis process is applied in industrial wastewater treatment, and the oxidation technology is feed water pre-treatment and water body disinfection. The combined application of iron-carbon micro-electrolysis process and oxidation technology is still limited in domestic research. The development and utilization of this process is conducive to saving the operating cost of the system. The iron-carbon micro-electrolysis process utilizes electrochemical action, redox action and flocculation. This process has been used in experimental research and practical applications for decades, and has achieved COD removal and chromaticity removal. Very satisfactory processing effect, COD removal rate is 45%~70%, and chroma removal rate is as high as 65%~90%. Because of its advantages of simple process, convenient operation and good treatment effect, it is widely studied and applied in the treatment of electroplating wastewater, petrochemical wastewater and pharmaceutical wastewater, especially in petrochemical wastewater and electroplating wastewater. The research of carbon microelectrolysis technology in tanning and printing and dyeing wastewater has also been widely concerned. Due to the wide range of sources and low cost of fillers in the iron-carbon process, the range of applications is also expanding. In the early years, the ironation of the iron-carbon bed will increase with the running time. Sometimes, the occurrence of this situation is irreparable, resulting in a waste of a large amount of iron-carbon filler, but the domestically developed iron-carbon stream The chemical bed reactor solves this problem very well. The research direction of Puyinworun environmental micro-electrolysis technology is aimed at the current high concentration of industrial wastewater and large amount of water. Micro-electrolysis has become more and more important in the pretreatment and advanced treatment of wastewater. This process is degrading organic matter, improving biodegradability and reducing The excellent performance in terms of cost is also valued by people. How to better apply micro-electrolysis to wastewater treatment, and the combination of micro-electrolysis with flocculation, Fenton, electrolysis, biological bed, etc. has become the object of research. And one of all the joint technology nodes is the continuous activity and efficiency of microelectrolysis. The formal engineering application of the catalytically active micro-electrolysis treatment system and filler jointly developed by Puyinworun Environmental Protection Technology Co., Ltd. and the research institutes has been in its sixth year since 2005, and in the past six years, our products have also been Innovate constantly in accordance with technical and practical requirements. A lot of practical research and exploration have been done to prevent the "primary battery" effect of the knot and improve the treatment efficiency of the waste water.

I System description:
Heat Shrinkable Tape is designed to protect the weld joint of buried or exposed steel pipelines and insulated pipeline. This sleeves are manufactured from high quality cross linked polyethylene material. Hot melt adhesive provides excellent adhesion with the surface of steel pipeline, PE coating. Meanwhile it forms a continuous and firm anti-corrosive system with the surface of the pipeline.
The Polyethylene Heat shrinkable Tape needs no primer nor patch closure and reduces application time and labour costs.
â…¡ Structure
The specification of the tape consists of three layers,
Adhesive: butyl rubber based hot melt adhesive
Film backing: Radiation crosslinked polyethylene
Interleaf:Antiadhesive Film Treated with Silicone

Wrap spirally the tape over foreign matters-free and preheated surface, beginning at least 25~50mm (1~2 ) onto pipe coating. Wrap the tape with enough tension to obtain conformability and with minimum 50% of overlapping, while removing the release liner. Warm the end part of the tape and press down firmly. Using a torch, start at the edge of the tape and heat circumferentially around the coated pipe.
Finish off by heating over the entire tape vertically to ensure a uniform adhesion and by using a roller or gloved hands to remove wrinkle and air.
