Method and system for controlling secondary water supply chlorination in complex loop

Abstract

The invention discloses a method and a system for controlling secondary water supply chlorination in a complex loop. The method comprises the steps of adding a sodium hypochlorite solution as a disinfectant to water in a water tank for disinfection, wherein the initial default adding coefficient is k1, the disinfectant is proportionally added according to the inflow rate Q1, and the adding amountQ2 is equal to k1Q1; after t1 time, adjusting the adding coefficient k according to the residual chlorine concentration signal of the effluent fed back from the water outlet of the water tank, whereink is equal to k1-k2, the adjustment time is t2, and k2 is the adding coefficient that needs to be adjusted; and when the residual chlorine concentration of the effluent fed back from the water outletdoes not reach a set value, refilling the disinfectant to the water tank, wherein the refilling amount V is equal to vk2, and v is the volume of water in the tank. The method and the system achieve chlorination disinfection on the water in the secondary water supply tank, and the equipment is intensive, efficient, simple and convenient; the whole equipment is fully automatic, the adding amount ofthe reagent is continuously analyzed and adjusted through the residual chlorine concentration of the effluent, thereby avoiding inaccurate adding amount caused by the concentration change of the reagent, and prolonging the changing cycle.

Description

technical field [0001] The invention relates to the field of water supply, in particular to a method and system for controlling the chlorination of secondary water supply by a composite ring, and provides a new idea and method for chlorination of secondary water supply. Background technique [0002] Since the pressure of the existing water plants (or pipe network booster stations) to the water supply network cannot meet the needs of high-rise water supply, the current high-rise water supply is all secondary water supply. Secondary water supply refers to the form in which we store the tap water of the urban water supply system through equipment, pressurize it, and then supply it to users. Secondary water supply is the only water supply method for high-rise residents, and the most commonly used method is non-negative pressure water supply. The non-negative pressure water supply equipment for general residents' water is equipped with water tanks, which can also ensure the safe...
