Abstract
The present invention relates to a water treatment method, in particular, it is a water treatment method for utilizing ozone to kill the fleas animal plankton. The method is characterized by pre-introducing ozone into the primary water before conventional treatment, the introduced guantity of ozone into every litre of primary water is 2.5-3.0 mg, and the ozone-introducing time is 15-20 min.
Description
Technical field: the present invention relates to a kind of water treatment method, particularly a kind ofly kill flea class zooplankton in the water so that its method that can effectively be removed.
Background technology: the eutrophication of water body provides living space for a large amount of breedings of Cyclop class, and human excessive fishing becomes the power of Cyclop rapid growth, in water factory's clean water basin of some big and medium-sized cities of China and even pipe network water, all once found Cyclop, even the accident of Cyclop took place to occur in a lot of pipe network water.Practice shows, Cyclop class vitality tanacity, and motility is arranged, easily penetrate the filter tank.Bigger Cyclop naked eyes as seen, like the white meat worm, it occurs in user's water, has not only violated in the drinking water sanitary standard the regulation of sensory properties index, has brought bad organoleptic effects to the user, what is more important, most of Cyclopoidas are the vectors such as pathogenic organisms in the water such as schistosomicide, nematode, thereby become a pathophorous important media, have brought very big threat for people's water safety problem, therefore, must from tap water, remove effectively.At this problem, most water factories adopt pre-prechlorination technology of throwing chlorine, ammonia to control, but there is following shortcoming in it: the one, and the pre-throwing of employing chlorine, ammonia process have increased the by product after sterilizing in the water outlet such as haloform, halogenated acetic acids etc. are carcinogenic, the content of mutagenic matter, and drinking water safety has been caused influence; Even adopt this technology still can not carry out removal in full force and effect on the other hand to water flea class zooplankton, in the water outlet of filter tank, still can detect the existence of a small amount of flea class zooplankton, make the safety water supply of water factory be difficult to guarantee.
Summary of the invention: the object of the present invention is to provide a kind of ozone that utilizes that flea class zooplankton is carried out the water treatment method that oxidation is killed, this treatment process is: pre-logical ozone in the former water before conventional processing, ozone feeding amount in every liter of former water is 2.5～3.0mg, and the time that feeds ozone among the Xiang Yuanshui is 15～20 minutes.The invention solves in the past and flea class zooplankton in the water is removed existing increase disinfection byproduct (DBP) and can not remove the problem of flea class zooplankton fully with pre-prechlorination technology of throwing chlorine, ammonia, the present invention adopts the water technology of pre-logical ozone, utilize the strong oxidizing property of ozone that water flea class zooplankton is carried out deactivation, make it in follow-up coagulation, precipitation and filtration process, obtain thoroughly effectively removing.Ozonization has very strong oxidation sterilizing effect, and does not produce " three cause " by products such as haloform, and the ozonize of water greatly reduces the mutagenicity of water than chlorination, and under the enough condition of ozone dosage, can not increase the mutagenicity of water.Experiment showed, method effect of the present invention obviously, reliable, kill method with chlorine and compare, ozone kills flea and is better than chlorine at aspects such as killing effect, security, economy angles and kills method.The present invention can effectively control the water flea class zooplankton in the water, thereby guarantees the qualified of effluent water quality index, and uses present method, and operational safety, convenience have high feasibility.
Embodiment one: present embodiment is a pre-logical ozone in the former water before conventional processing, ozone is produced by ozonizer, add by closed conduit, the ozone feeding amount in every liter of former water is 2.5～3.0mg, and the time that feeds ozone among the Xiang Yuanshui is 15～20 minutes.
Embodiment two: present embodiment is, in Xiang Yuanshui, add ozone before the dosing coagulant, because it is very fast that ozone scatters and disappears in water, its killing action obviously is embodied in after the feeding 20 minutes, the different actual water body that utilizes experimental summary to go out consumes the rule of ozone, in production practice, verify, draw actual water body feasibility and add scheme, when ozone dosage is 2.88mg/l, can reach the purpose of whole deactivation Cyclops, can when feeding ozone, adopt the ozone retrieving arrangement to reclaim.
Claims (2)
1, a kind of water treatment method that utilizes ozone kill fleas class zooplankton is characterized in that in the former water before conventional processing pre-logical ozone, and the ozone feeding amount in every liter of former water is 2.5～3.0mg, and the time that feeds ozone among the Xiang Yuanshui is 15～20 minutes.
2, the water treatment method that utilizes ozone kill fleas class zooplankton according to claim 1 is characterized in that ozone produced by ozonizer, adds by closed conduit.
