Project introduction:
Water supply projects are projects that supply living and production water as well as fire-fighting water, road greening water, etc. to residents and factories, mines, and transportation enterprises. It consists of water supply sources, water intake structures, raw water pipelines, water supply treatment plants and water supply pipe networks. It has the function of collecting and transporting raw water and improving water quality. ①Water supply source. There is surface water, groundwater and reused water. Surface water mainly refers to water in rivers, lakes, reservoirs and oceans. It is abundant and is the main source of water for cities and factories, but its water quality is susceptible to environmental pollution. Groundwater is clean and has stable water temperature, making it a good source of drinking water. Reused water is Reuse or recycling of industrial water. About 60% to 80% of industrial water in advanced countries is reused water. ②Water intake structure. There are surface water abstraction structures and groundwater abstraction.
Drainage projects are projects that remove human domestic sewage, various wastewaters from production, and excess surface water. It consists of a drainage system (or ditch), a wastewater treatment plant, and a final treatment facility. Lifting facilities (such as drainage pumping stations) are also usually included. ① Drainage piping system. The pipe network that collects and transports wastewater (sewage) has a combined pipe system and a diverted pipe system. The combined pipe system has only one drainage system, and rainwater and sewage are discharged through the same pipe. The diversion pipe system has two drainage systems: the rainwater system collects rainwater and cooling water and other industrial wastewater with very low pollution levels and is discharged directly into the water body without treatment. Its pipes are called rainwater pipes; the sewage system collects domestic sewage and needs to be treated before it can be discharged The pipes for industrial wastewater that enters water bodies are called sewage pipes. ②Wastewater treatment plant. Including sedimentation tanks, sedimentation tanks, aeration tanks, biological filters, clarifiers and other facilities as well as pumping stations, laboratories, sludge dewatering machine rooms, repair factories and other buildings. The general goal of wastewater treatment is to remove suspended solids and improve oxygen consumption. sex, and sometimes disinfection and further processing. ③Final processing facilities. Depending on the drainage objects, water pumps or other water-lifting machinery will be installed to discharge the wastewater that meets the prescribed discharge requirements after treatment in the treatment plant into water bodies or on land.
Fire protection engineering includes urban and building fire protection system engineering. The content includes fire hydrant system, automatic sprinkler system, water curtain fire extinguishing system, etc.
Engineering Technology Major:
Water supply and drainage engineering technology is a technology strongly promoted by the country. It is conducive to environmental protection such as municipal development policies and energy conservation and emission reduction. It can also promote the rapid development of the construction industry. However, there is currently a serious shortage of talents majoring in water supply and drainage engineering technology.
