Water treatment method for killing living animals such as fleas by O3/H2O2

Abstract

A water treating method for killing the flea kind of zooplanktons by use of O3 / H2O2 features that before the water is conventionally treated, the O3 and H2O2 are proportionally added to it and then stayed in water for 20-30 min.

Description

Technical field: [0001] The invention relates to a water treatment method, in particular to a method for killing zooplankton such as fleas in water so that they can be effectively removed. Background technique: [0002] The eutrophication of the water body provides a living space for the massive reproduction of Cyclops, and the overfishing of humans has become the driving force for the rapid growth of Cyclops. Cyclops have been found in the clear water ponds of water plants and even in the water of pipe networks in some large and medium-sized cities in my country, and there have even been many accidents in which water fleas have appeared in pipe network water. Practice has shown that Cyclops have tenacious vitality, mobility, and easy penetration of filters. The larger Cyclops can be seen with the naked eye, like white meat worms. Its appearance in the user's water not only violates the regulations on sensory traits in the sanitary standards for drinking water, but also bri...

Problems solved by technology

The larger Cyclops can be seen with the naked eye, like white meat worms. Its appearance in the user's water not only violates the regulations on sensory traits in the sanitary standards for drinking water, but also brings adverse sensory effects to users. More importantly, Yes, most Cyclops are intermediate hosts of pathogenic organisms in water such as schistosomes and nematodes, thus becoming an important medium for spreading diseases and posing a great threat to people's water safety. Therefore, drinking effectively removes from water

In response to the above problems, most water plants use the pre-chlorination process of pre-dosing chlorine and ammonia for control, but it has the following disadvantages: First, the use of pre-dosing chlorine and ammonia technology increases the by-products such as trihalomethanes after disinfection in the effluent water , haloacetic acid and other carcinogenic and mutagenic substances, which have affected the safety of drinking water; on the other hand, even if this process is adopted, it still cannot completely and effectively remove daphnia zooplankton, and it can still be detected in the effluent of the filter The existence of a small amount of flea-like zooplankton makes it difficult to guarantee the safe water supply of the water plant
