Residual chlorine plays a vital role in the water treatment process. Its main functions include disinfection, prevention of secondary pollution, and maintaining stable water quality. The following are some specific roles of residual chlorine in water treatment:   Sterilization and disinfection As a strong oxidant, residual chlorine can effectively kill bacteria, viruses and other microorganisms in water, thereby preventing water pollution and the spread of waterborne diseases. By detecting the residual chlorine concentration, it can be ensured that the disinfection effect of water meets the hygienic standards and ensures the safety of the water supply system.   Preventing secondary pollution During the process of water being transported from the water plant to the user, it may be secondary polluted by pipelines and facilities along the way. The presence of residual chlorine can continuously sterilize and prevent the water from being contaminated again during the transportatio...

Definition and measurement object Soil water potential sensors are mainly used to measure soil water potential. Soil water potential refers to the relative level of soil water energy. It is used to illustrate the energy state of soil water and its dynamic changes, and can provide necessary parameters for soil management and water conservancy project control.   Measurement content and method The measurement of soil water potential usually covers the determination of matrix potential, solute potential and gravity potential. Different types of potential have different measurement methods: Matrix potential: commonly used to measure by suction plate, ultra-centrifuge , moisture absorption method, sand funnel and pressure membrane instrument. Solute potential: can be measured by osmotic pressure method, that is, calculated by measuring the concentration of aqueous solution. Gravity potential: calculated according to relative height difference. Pressure potential of saturated soil: can b...

horological data plays a vital role in urban planning. It not only provides a scientific basis for urban planning, but also has a far-reaching impact on the sustainable development of cities. The following are several major application areas of horological data in urban planning:   Predicting flood risks horological data can help planners predict and assess urban flood risks, thereby reducing the impact of floods on urban planning. By analyzing data such as precipitation, runoff, and groundwater levels, areas susceptible to floods can be identified, and corresponding flood prevention measures can be formulated accordingly.   Optimizing urban drainage systems Analysis of urban horological monitoring data can identify problems in urban drainage systems and propose optimization plans. For example, by analyzing runoff data, the design of urban drainage systems can be optimized to reduce the risk of urban water logging.   Rational allocation and utilization of water resources ...

Regulating soil temperature The vegetation coverage in urban parks is high, and plants such as trees and grass can block direct sunlight and reduce the solar radiation energy received by the soil surface. During the day, the canopy of plants is like a big umbrella, blocking a large amount of heat from being directly transferred to the soil, thereby reducing the temperature rise of the soil. For example, in the hot summer, the temperature of the soil covered with park vegetation may be several degrees Celsius lower than the temperature of the bare urban ground soil. At night, vegetation can play a certain role in heat preservation, slowing down the rate of heat loss in the soil, so that the soil temperature will not drop sharply and remain relatively stable. This regulation of soil temperature helps to maintain the activity of microorganisms in the soil and the stability of the soil ecosystem.   Influence on soil moisture evaporation The vegetation in urban parks absorbs moisture fr...
