| At present, China's industries are vigorously promote energy saving and consumption-reducing technology. As the large departments of electricity consumption, waterworks has great potential for energy saving and consumption–reducing. In the water industry, the pump energy consumption accounts for 80 percent to 90 percent of corporation energy consumption.Therefore, we must strengthen the management of water production operations, increase energy saving and consumption–reducing technological transformation efforts, under the premise of safety, quality water, reduce water costs and increase the economic efficiency of the water enterprises.The article discusses the topic source, analysis of researching waterworks energy saving and consumption–reducing status at home and abroad. In view of the waterworks power consumption, drug consumption, the consumption of chlorine problems and the status of waterworks structures, with examples of Zhongshan Sino-French Water Supply Co. Ltd. From the technical and economic comparison analysis, identified various energy saving and consumption–reducing technology in the waterworks:1. Cutting the pump impeller within the limits of the impeller cutting technology, with less investment, energy saving, economic and social benefits obvious advantages should be vigorously promoted.2. Made the input-drug system and input-chlorination system automated is to ensure that inputting accurate and guarantee for water quality, an effective way to control costs.3. Optimization choices of waterworks structures, the design phase should be according to the raw water quality to determine suitable processing technology, comparative analysis of the advantages and disadvantages of the various structures and meet with the realities of the situation, achieving the lowest energy consumption and material consumption. The old waterworks for energy-saving and tapping potential transformation of structures on the tank, as far as the reaction tanks and sedimentation tanks, improved import and export flow conditions can increase handling capacity; The filter, through to the rapid filter (single-water backwashing) and V-type filter (gas-water backwashing) performance comparison, backwash water alone will transform the gas water filter backwash is an important way of saving energy. |
