Abstract: With the frequent appearance of haze weather, haze-preventing has become one of the serious environmental problems. Among all measures, preventing inhalable particulate matter from the source is one of the most effective ways to eliminate haze. Based on the traditional water mist dust suppression technology, this paper developed a water-saving integrated system, by exploiting PROFIBUS-DP to connect water mist dust suppression system to gantry crane in port. This integrated system was demonstrated accurately spraying water mist while the crane dropping down coal. In this way, the suspended particulate matter is successfully inhibited, while fresh water is saved.

Abstract: Water shortage due to deterioration of water quality is quite serious near Hangzhou Bay, that is connected with regional water sustainability in water's five aspects, namely drainage water, flood water, sewage, water supplies, water-saving. Jiaxing city is near the Shanghai and Hangzhou city, located at Zhejiang province in the South China, mainly with totally three river systems. The research focuses on water pollution of Jiaxing city, and summary to improve regional water environment social economic system in the near future are given.

Abstract: Water pinch technology for the water system of enterprises is one of the focuses on water-saving and emission reduction research of enterprises in recent years. This technology is characterized by the design minimal fresh water consumption and waste water emissions minimum and aims to achieve economic benefit optimum process integration technology. The application of water pinch technology to integration and optimization of the water system was reviewed, and engineering application examples of water pinch technology were introduced. The water pinch technology is simple and intuitive. Besides, it could achieve optimal solution for a single impurity system. But for multiple contaminants system, this method will no longer apply. Taking into account its limitations, the possible optimization solutions to application of water pinch technology in combination with other types of analysis tools in enterprise water system were put forward.

Abstract: Using the analytic hierarchy theory and method to evaluate the related project for optimal selection of water-saving irrigation in the area of Xiaoshan in Zhejiang province. Establish the analysis model of optimal irrigation level and get the total ordering of water saving irrigation mode. Ultimately choose the sprinkling irrigation as the optimal irrigation.

Abstract: In order to solve the problem which is very common when we use a solar water heater for a shower but the hot water can not come immediately because of the cooled water remained in the pipeline, a no-pump cycling water-saving equipment is designed based on a pressure-regulated suction device, temperature acquisition control circuit and a water-saving box. The kinematics and mechanics parameters are confirmed on the result of calculation and software simulation, and are tested by doing physical experiment. It can make it come true to economize the water and energy for solar power heater.

Abstract: Abstract. A great number of agricultural sheds are used in the China's farmland. With the development of science and technology and water use of tension , nowadays various proposed micro-irrigation techniques for the agricultural shed irrigation have been put forward , but as high-tech product and extremely high cost, the farmers cannot afford it, thus they have no choice but to use the traditional slow methods. To seek for the low cost of water-saving irrigation way, this paper put forward the original canopy stents arch tube after drilling converted into a canopy of the support and the unity of the new irrigation micro-irrigation technique, which has been combined with the new type of irrigation trellis to make complete design planning.

Abstract: Through the analysis on the situation of water-saving in water supply and drainage system of our country, we recognize that there are still some problems in water-saving of buildings and we still have many works to do on water-saving. In order to build a water-saving society, and to save and protect water resources, we must improve our consciousness on water-saving, innovate water-saving technology, and promote the applications of water-saving equipments and facilities.

Abstract: A type of wastewater reuse system for domesticity with remote-control is presented in this paper. For domestic water-saving, the wastewater reuse system is designed via hydromechanics, and its remote-control system is discussed. The system consists of wastewater storage tank, electromagnetic valve, electronic remote-control device, and pipelines. The principle of its water-saving is also analyzed in three control models. The results indicate that the wastewater reuse system can make the best of reusing domestic bathing and washing wastewater to wash down toilet bowl in order to save water supply. Electromagnetic valve is convenient to control and has good seal performance for avoid wastewater leak. Two enactment time control models and a manual control model can effectively satisfy with user, farther to save wastewater

Abstract: The situation was analyzed in this paper about the wastewater treatment of the nylon chemical engineering. According to the types and characteristics of the industrial water, the processes were improved including cooling water, condensate water, desalination water and wastewater. The results indicated that the recycling efficiency was increased and the unreasonable emissions were reduced, which were beneficial to save water, reduce production costs and reduce pollution to the environment.

Abstract: Abstract. In order to promote the application of water-saving technology, to use natural resources effectively and to realize the sustainable development of our economy, we should explore and summarize the experience of water-saving for water supply and drainage and meanwhile create conditions for the design and layout of buildings and districts.
