Synthesis of Environmental Functional Materials and its Application in Domestic Sewage

Abstract

Environmental functional materials have unique physical, chemical and biological properties, and have excellent environmental purification effect, so they can be used to eliminate or reduce water environmental pollution, play the role of decolorization, deodorization and sterilization. In this paper, the composite method was used to prepare environmental functional materials, and the treatment effect of domestic sewage was studied. COD, TP and TN were the research indicators. Single factor experiment and orthogonal experiment were carried out. The results show that the best reaction conditions of COD, TP and TN are as follows: reaction time is 45 min, 55 min, 45 min, dosage is 0.180 g, 0.100 g, 0.130 g, temperature is 40°C, 60°C, 40°C. The best removal rate of COD, TP and TN was 81.8%, 59.4%, 51.1%, respectively. The treatment effect of environmental functional materials of COD in domestic sewage is better than that of TP and TN. Therefore, environmental functional materials can be used to treat sewage of high concentration of COD.
