Description
Technical field
The present invention relates to a kind of chloramines preparation facilities and method thereof that automatically regulates pharmacy response usage ratio according to variations in temperature. Relate in particular to a kind of chloramines preparation facilities and method thereof that automatically regulates ammonium chloride and clorox usage ratio according to variations in temperature.
Background technology
Liquid chlorine is during as disinfectant, because its cost is reliably widely used compared with low, technical maturity, effect stability. But chlorine is hypertoxic dangerous material, the steel cylinder of storage chlorine belongs to high-pressure bottle, has potential threat, and can react with free chlorine generation carcinogen (as haloform) when organic matter is more in water. And Comparatively speaking, chloramines as disinfectant advantage more as: in (1) chloramines and water humic substance effect less, the therefore general little generation haloform of chloramines disinfection (THMS) and halogen acetic acid (HAAS), generation Cancer-causing mutation compound also fewer. (2) good stability of chloramines, penetration capacity is stronger than chlorine, duration in pipe network is long, can effectively control breeding and the biomembranous formation of harmful substance microorganism in pipe network, sterilization persistence is strong, thereby can effectively suppress the breeding of remaining bacterium, more can ensure the requirement of the residual chlorine amount of pipe network. (3) chloramines disinfection is to be had an effect by the HClO slowly releasing, therefore oxidability comparatively speaking a little less than the rate of exchange, can slow down the residual stink of liquid chlorine disinfection greatly. (4) chloramines disinfection is less to the corrosivity of water supply network.
In recent years, due to the regulation of the concern to DBPs DBPS and Disinfection Byproducts in Drinking Water restriction, more and more water factories adopt chloramines to replace liquid chlorine disinfection as disinfectant. At present, preparation chloramines adopts artificial preparation then to add mostly, and the generation concentration of still adopting the chloramines of preparing is in this way subject to the impact of environment temperature, is unfavorable for quantitatively adding of disinfectant. For addressing the above problem, a kind of chloramines preparation facilities that automatically regulates pharmacy response (ammonium chloride solution and liquor natrii hypochloritis) usage ratio according to variations in temperature of design.
