A sewage treatment plant that will serve 200,000 people will look like, how to dispose of sewage? 3, the reporter went to the construction of Minhou Zhuqi sewage treatment plant "Quest." Bamboo Qi Town sewage treatment plant is located in Bailong village, backing the river, the surrounding scenery pleasant. The construction of sewage treatment plant here, from the very beginning, the local villagers' concerns are unavoidable, for example, will not damage the environment will not affect everyone's normal life? "On the contrary, we are a factory established to protect the local ecological environment," said Wang Xianlin, project manager in charge of the project. Originally, there was no sewage treatment plant in the area before. The large amount of domestic sewage of the villagers was discharged into the surrounding natural water only after simple treatment or no treatment at all, resulting in environmental pollution such as water, soil and air. With the speedy construction of Minhou Zhuqi new area, large projects such as the Jinshui Lake Tourism Complex and Minyue Water Town have settled in succession. The industry and population in Zhundi continue to gather, and the discharge of production and domestic sewage will also increase sharply. In order to create a livable environment, especially to protect the water environment in the Min River basin, the construction of sewage treatment system project is imminent, and the project construction of Zhuqi Township Sewage Treatment Plant is put on the agenda. It is understood that, Zhuqi Township Sewage Treatment Plant and supporting pipe network project a total investment of 123 million yuan, included in Fuzhou 2017 tackling projects. Construction started in December last year, plans trial operation in November this year, the recent day handling capacity of 10,000 tons. The long-term sewage treatment capacity of the project will reach 50,000 tons per day. Its service scope includes Baisha Area (west of Minjiang River), Jinshui Lake Area and Zhuki Area, serving 200,000 people. About 14 km of sewage pipe network connecting the sewage treatment plant and the surrounding 7 administrative villages is also stepping up its laying. Bailong Village, where the project is located, will rebuild villagers 'self-built houses' sewer network in the near future. Afterwards, all sewage from the village will be treated in WWTP. A large number of sewage into the sewage treatment plant, the treatment process is like? Minhou County Water Company Manager Zhang open country to answer our doubts. He said that Zhuqi Township Sewage Treatment Plant adopts advanced sewage treatment technology, domestic sewage comes in from the sewer pipe and reaches the standard discharge, with a "seven-off" in the middle. The first level, between the coarse grid, filtered out "big rubbish", such as branches and leaves, mineral water bottles, plastic bags, etc .; The second pass, through the fine grid and cyclone grit chamber, filter out "small garbage", such as fine sand and so on; The third stage, the filtered sewage came to sediment sand pool, sediment deposition; The fourth pass, into the oxidation ditch, biological reactions, degradation COD, BOD, ammonia nitrogen, total phosphorus and other organic matter; Fifth off, into the second settling tank, mixed liquid mud water separation, clarification of sewage; Sixth, once again precipitation, filtration, to further reduce pollutants; Seventh off, disinfection, discharge after compliance. It is understood that, in the process of production and operation of Zhuqi Township Sewage Treatment Plant, most of the processes are carried out in the underground professional facilities and equipment, silent and tasteless, and will not affect the surrounding environment. Plant construction will also be based on garden design, green area of ​​30% or more.
A Heat Exchanger Unit is a device used to transfer thermal energy (heat) between two or more fluids. Heat exchangers are used in a wide variety of applications, such as heating and cooling of buildings, industrial processes, and power generation.
The heat exchanger unit essentially consists of heat exchangers such as Plate Heat Exchanger, Shell and Plate Heat Exchanger, or other counterpart, a circulating pump, a fluid make-up pump, thermometers, a filter, sensors, a pipeline and valves. It is also possible to design a temperature control system, pressure stabilization system, variable-frequency controller, heat metering and communication controller, etc. according to the client`s requirements.
Big advantage of heat exchanger unit is that, by adopting a modularized structure, it maximizes each component`s function to the most. The precise control for heat exchange process also saves time and efforts for maintenance and installation.
Feature is that intelligent control, excellently energy-saving, high automation and easy to operate, high cost performance and wide application.
