Overview of Energy Saving and Consumption Reduction Technologies for Rural Water Supply in Zhejiang Province
Energy saving and consumption reduction is the key to reduce operational costs,and ensure long term positive operation of rural water supply.This paper briefly analyses the existing problems of electricity,chemical and water consumptions in rural water supply of ZheJiang Province.Relevant researches and technical measures were overviewed from three aspects,including reducing electricity consumptions by optimizing water supply pumps configuration and pump retrofit,reducing chemical consumptions by improving adding mode and structure renovation,and reducing water consumptions by upgrading the operation and maintenance level of water-treatment facilities and pipeline networks.The analysis showed that current measures to save electricity consumptions mainly involve upgrading the pressurization system,which has characteristics with targeted and high efficiency,but costs highly.Current measures to reduce chemical and water consumptions mainly focus on dealing with various raw water conditions and supply needs by precision control,which has wide applicability and obvious benefits,but requires high standard management.It was suggested to strengthen the research in pump development,automation upgrading and management competence improving in the future,in order to promote the sustainable development of rural water supply in Zhejiang Province.
