| TianJin, that is relative shortage of the water resources. Because the traditionalmodel of economic development and rapid expansion of population, we are faced withincreasing pressure on water resources of the trend. If we can better get wastewatertreatment in our city, and finding the new technology with high efficiency and lowcost in urban, not only can improve the environment condition and improve thepeople’s living standards, but also can make environment of our city developingsustainable.This paper based on the features of soil and water in the constructiondemonstration zone, By understanding the different soil permeability, choosing areasonable way of filling ratio, getting correlation analysis about the three factorswhich is hydraulic loading, pollution load, flow rate and the effect of wastewatertreatment. Based on the results, we will cultivate the active bacteria. This is a newtechnology, will also be effectively applied to the municipal wastewater treatment infuture.At present, most of the municipal wastewater treatment plant to pay the cost ofelectricity in the total running between60%and70%, with pharmaceutical costs,labor costs and transportation costs, making the plant can not function properly.Therefore, how to improve efficiency of the municipal wastewater treatmentplant,how to reduce operating costs,energy consumptionb, managementrequirements, and how to reduce the impact on environment, as the future problem tobe solved.This paper studies the land filtration treatment technology, through the analysisof "soil-microorganisms-animals-Plants" and the ecological system of self-controlmechanism and the comprehensive purification of pollutants, to achieve theadsorption, microbial degradation, nitrification and denitrification, filtration,absorption, redox simultaneously. This technology will enable water resource andharmless, and with less investment, low running costs, ease management, dealing withgood results and stability advantages. |
