Design and Simulations of Water Purification Heating System in Cold Rural Areas
2015
Biological treatment process of water purification often cannot be completed under low temperature in northern rural areas. On the basis of determining the thermal characteristics of clarification pool and biofilter pool of the purification systematically, we designed and proposed a purification heating system in which solar collector and straw boiler run in parallel, and further built the mathematical model of purification. We simulated heating effect on clarification pool and biofilter pool when heating pipes were placed in different locations by using Fluent. It indicated that, the heating system mentioned in this article allows the temperature in clarification pool and biofilter pool of the purification meeting the demands of water treatment, thus the system has theoretical significance and value of engineering generalization.
