In this article, the results of the research on organic pollutant treatment in the wastewater of printing processes on fabric by H2O2 under the catalytic role of the complex between ion Ni2+ and Citric acid (H4L) were presented. The condition of pH, H4L/Ni2+, H2O2, Ni2+ concentration has been explored to get the optimal conditions for improving COD efficient treatment. The results provide the solutions of the homogeneous complex  catalysts in the industrial wastewater treatment at room temperature and atmosphere.

Biodegradation Process

The metabolic potential of microorganisms plays an important role in the biodegradation of petrochemical waste. The characteristics of the microbial community involved in industrial wastewater treatment have been reviewed in many studies. Within this review, a complete understanding was provided about the characteristics of microorganisms such as bacteria, yeast, micromycetes, and the role of enzymes in the biodegradation process. Data on the structure of the microbial community and the metabolic potential of individual strains are promising for improving the procedure for preliminary wastewater treatment with an increase in the spectrum of strains that can degrade more toxic and resistant xenobiotics. Deciphering the structure of the microbial community is the key to create a rationally and functionally stable purification system.

The article deals with the role of electrodes materials in improving the industrial wastewater treatment from pollutants by electrochemical action. The instability constants of the complexes and coordinated ligand molecules were calculated. Based on the research conducted regarding the rationalisation of the poly-ligand electrolytes and electrolysis modes, a variative flow scheme of the coatings deposition by triple alloy has been developed. The corrosion resistance characteristics of the coatings obtained in the form of alloy, that were obtained from complex electrolyte that satisfy the necessary coatings requirements for effective treatment of wastewater have been researched. The obtained coatings have better corrosion resistance than in special steels of electrochemical purpose.

Abstract With the development of industry, the industrial wastewater produced by all walks of life become more and more, which cannot be overestimated, studies on the technology of industrial wastewater treatment are conducive to the development of industrial wastewater treatment. The paper analyzes in detail the treatment methods of industrial wastewater, including physical method, chemical method and biological method, The application of the three methods is relatively simple, and several methods have been merged. Moreover, the current industrial wastewater treatment in the paper industry, printing and dyeing industry, pharmaceutical industry is analyzed, the results show that industrial wastewater treatment in the pharmaceutical industry is difficult. In addition, the role of Aquamats ecological technology in industrial wastewater treatment is analyzed. In addition, this paper analyzes and discusses the status quo of industrial wastewater treatment and the main existing problems, and proposes countermeasures to further improve the treatment level of industrial wastewater.
