Analysis Of Water Quality Problems In Xi’an Moat And Exploration Of Technical Scheme For Upgrading

As a typical urban river,xi ’an moat is an important part of the ancient city wall defense system.With the continuous social and economic development of xi’an city,as well as people’s imperfect protection measures and insufficient awareness to the value of water environment,which may pose a high risk to the water quality of the xi’an moat.As a result,polluted water may adversely affect the urban ecological environment and residents’ health,as well as restricted the development of urban economy and society.This paper takes xi ’an moat as the research object to evaluate the water quality though investigation and analysis of the general situation of the moat,the water system structure and the current water quality as well.Furthermore,achieve the technical scheme of moat upgrading,which may provide supporting basis for the comprehensive improvement and transformation of the moat in the subsequent section.The main research contents of this paper include the following aspects:(1)Through the analysis of water quantity and water quality in time and space,it is clear that the main factors affecting the water quality of the moat are insufficient water quantity,poor fluidity and unsatisfactory raw water quality;(2)In view of the water quality problems existing in different sections of moat,the comprehensive water quality improvement measures of the Moat is "Source controlling,Flowing,Purifying,Repairing".(3)Through the simulation calculation and analysis of the model,it is clear that the proposed scheme can achieve the expected goal of improving the water quality of the moat.
