PPPnamelyPublic-Private-PartnershipThe abbreviation of the letters refers to a partner-like cooperative relationship formed between the government and private organizations, as well as between the government and social entities(Enterprise)Establish a community relationship featuring "shared benefits, shared risks and full-process cooperation", so that all parties involved in the cooperation can achieve more favorable results than expected when acting alone.
PPPIt has the two major features of both capital conservation and efficiency improvement. Broadly speaking,PPPEmphasizing a cooperative relationship involves many business models, such asBOT,TOT,ROT,BOO,PFIWait.
willPPPThe model is applied to water treatment.At presentPilot programs have begun in many regions across the countryPPP"Mode"Work.The National Development and Reform Commission reported that the municipal government of Xiamen, Fujian Province, has made attempts in multiple fieldsPPPMode.It is learned that the new water project is currently undergoing preliminary research(Seawater desalination, wastewater treatment and reuse, and rainwater collection and utilization)After its construction, it will mainly supply water for industrial and social services in Xiamen, timely making up for the shortage of water resources and the increasing water consumption in Xiamen year by year, revitalizing the existing water resources of the city and enhancing the city's water resource risk resistance capacity. In addition to seawater desalination, Xiamen is also stepping up efforts in the freshwater sector.
Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.
The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.
Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
