Water supply period refers to the period when a place (or an enterprise) needs to provide safe, stable and qualified water to this direction in order to achieve a certain goal. This period is called water supply period. Generally speaking, this word is used more in agriculture. Cities generally use "peak water supply period" and "general water supply period".
Question 2: What does municipal water supply mean? 1. The urban water supply system consists of transportation facilities such as water treatment facilities and pipelines.
2. Water treatment facilities include lifting pump station, circulating filter pool, disinfection facilities, water quality inspection and supervision system and other water supply systems.
Question 3: What is the tap water supply system? Tap water supply system consists of microcomputer frequency conversion control cabinet, water pump unit, pressure sensor liquid level controller (optional), pipe fittings and valves. The tap water supply system adopts high-performance imported variable frequency governor and advanced digital microcomputer control technology, which has a high degree of automation and can realize multiple control modes and multiple start-stop modes of constant pressure variables, multiple constant pressure variables and variable pressure variables. The energy-saving effect is remarkable. Microcomputer control can realize variable frequency soft start of multiple pumps, with no impact current and little mechanical impact wear, which can prolong the service life of box-type pumping stations, improve the stability of the system and reduce the impact on the power grid. The technical department of Changsha Huadu Water Supply Equipment Co., Ltd. has finished answering.
Question 4: What industry does the water supply company belong to? 5 points are classified according to national economy industry, version 20 1 1.

Tap water production and supply
Refers to the activities of storing and purifying natural water (groundwater and surface water) to meet the drinking water or other water standards and supplying it to families, enterprises and other users.
Question 5: What is a water supply area? This is high school geography, and the water supply area is the water supply area.
Question 6: What is direct water supply? Direct water supply means that water comes from tap water and is directly connected to users without secondary pressurization. Generally, it is a multi-storey residential area with low floors, which is used by factories or businesses.
Question 7: What is urban water supply to supply urban domestic water and industrial water with specified quantity, quality and pressure? Also known as urban water supply. Urban domestic water is divided into: water for residents' daily life, such as drinking, washing and house greening; Municipal public water, such as commerce, service industry, schools, hospitals, fire protection, urban greening, street spraying, garbage removal, urban river and lake water supply and suburban commodity vegetable fields. Industrial water is mainly used for cooling, washing, temperature regulation and humidity regulation. Urban water supply sources are divided into surface water and groundwater. Surface water includes water in rivers, reservoirs, lakes and oceans. Groundwater includes well water, spring water and groundwater.
The water supply system is divided into four parts: water intake, water delivery, water treatment and water distribution. Tube well, large mouth well, radiation well and seepage canal are commonly used to take groundwater. Fixed water intake structures can be built to obtain surface water, such as coastal or riverbed-based water intake structures; Movable pontoons and cable car water intake structures can also be used. Water is transported from the water intake building to the water treatment plant through the water conveyance channel. Water treatment includes clarification, disinfection, deodorization, iron removal and softening; Industrial circulating water often needs cooling, and seawater and brine need desalination or desalination. The treated water that meets the water quality standard is delivered to users through the water distribution network.
Urban water supply system is affected by water source, topography, urban planning and other factors, and can be arranged in the following basic ways:
(1) gravity water supply system, that is, using topographic gravity to supply water;
(2) The water pump lifts the water supply system;
③ Single water supply system;
④ Multi-source water supply system;
(5) water supply system;
⑥ Partial (water) pressure water supply system.
The above systems can be combined into a new water supply system, such as multi-source gravity water supply system. In addition, industrial water supply includes circulating water supply and sequential water supply in addition to direct water supply (that is, it is directly discharged into the discharge area after one use). Circulating water supply is to treat the used water properly and then reuse it. Sequential water supply is to supply water to users with high water quality requirements, directly or slightly treat it after use, then send it to other users with low water quality requirements, and finally discharge it into the discharge area.
Question 8: What does full-time water supply mean? "Full-time water supply", playing word games, uninterrupted water supply and 24-hour water supply. It all means the same thing, that is, don't stop the water:)
Are you talking about the hotel?
Hehe, good luck.
Question 9: What do you mean by quality water supply? Candidates who enroll separately enter the school in the same year as those who enroll online in the college entrance examination. When students graduate and enter school, tuition fees and accommodation fees are the same. Candidates enrolled in separate schools, such as individual enrollment, counterpart enrollment, and unified examination enrollment, have the same welfare benefits such as starting time, academic system, diploma, charging standard and scholarship ~ ~
