Abstract
The present invention relates to process of treating non-degradable organic matter in drinking water by means of electron beam irradiation, and belongs to the field of deep water treating and environment protecting technology. The process includes the following steps: storing tap water in a water reservoir, making water pass through an electron accelerator in the flow rate controlled with a flowmeter to accept electron beam irradiation, further irradiating treatment in a irradiating container, and filtering in a sand filter to eliminate granular suspended matter to obtain drinking water. The electron accelerator has electron energy of 0.7-0.9 MeV and electron beam strength of 9-11 mA, and the treating time is 60-120 sec. The process is simple, and has effect of degrading organic matter in water and capacity of raising quality of drinking water.
Description
Technical field
The present invention relates to the method for hardly degraded organic substance in a kind of processing drinking water, mainly is the technology of handling by electron beam irradiation, belongs to water depth and handles and environmental protection technical field.
Background technology
City resident's tap water source is mainly the tap water in the public supply mains, and its problem that mainly exists is: inorganic ion content height such as chlorion; Adopt the hypochlorous acid sterilization in the tap water manufacturing processed, it combines with organic substance in the water and generates chlorinated compound, its strong toxicity; In addition, the organism kinds in the tap water is various, and complicated component also contains pesticide residue, medicine intermediate material sometimes in the tap water; Some harmful microorganism also are that hazardness is arranged; In this case, traditional pre-treating process can not be dealt with problems fully the past.
The treatment process of city resident's tap water is essentially the method that the physics method combines with chemical method at present, generally is divided into three steps: (1) filtering-depositing; Natural water flows into barrier, settling tank through water inlet pipe, effectively removes the macrobead suspended matter in the natural water body; (2) with the coagulating agent coagulating treatment through sedimentary water, in water, add chemicals such as alum according to national standard and be used to remove water small particles suspended substance; This method can produce a large amount of solid waste, produces secondary pollution, and can not remove the difficult degradation that is dissolved in the water, harmful poisonous organism; (3) sterilization; As disinfectant, but organic substance is in conjunction with generating chlorinated compound among the Yi Yushui with hypochlorous acid, and its toxicity is very strong, can have a negative impact.
Summary of the invention
The purpose of this invention is to provide a kind of method and treatment unit thereof that utilizes electron beam irradiation advanced treatment tap water.
A kind of method of utilizing the electron beam irradiation processing drinking water of the present invention, it is characterized in that having following process and step: will flow into as the former water in tap water source and be stored in the water reservoir, control its flow by-under meter adjustment, and make former water average rate stand the irradiation of electron beam by irradiation device for electronic accelerator, enter the radiation treatment container subsequently, further stand irradiation; The water of aggregation in this container flows into husky filter device by pipeline, to remove the particle suspensions in anhydrating; Treated then water flows out at the water outlet on husky filter device top, and this water is the Drinking Water that direct supply people use; Energy 0.7～the 0.9MeV of described rumbatron accelerated electron, electronic beam current intensity is 9～11mA, the treatment time is 60～120 seconds.
A kind of isolated plant that utilizes the method for electron beam irradiation processing drinking water, it includes water reservoir, under meter, rumbatron, husky filter device and radiotreatment container; It is characterized in that: water reservoir, radiation treatment container, husky filter device form an open piping system by pipe connection; Rumbatron directly be installed on the radiation treatment container directly over, make the direct radiation treatment container of beam energy directly over, make the direct irradiation of beam energy and act on the former water current body; The top that is located at the husky filter device of device tail end is provided with an outlet pipe, and tap water is after treatment flowed out directly by this outlet pipe to be drunk for life.
The principle of the inventive method is: electron beam is the high-energy electromagnetic radiation that is produced by rumbatron, and the energy by controlling electron beam can make the penetration power of electronics reach service requirements.Ionizing rays makes hydrolysis produce hydroxyl radical free radical, hydroperoxyl radical and hydrated electron, the organic substance generation oxidizing reaction that contains in they and the water, thus play the effect of degradation of organic substances.
The advantage and the effect of the inventive method are: technology is simple, and is easy to operate, non-secondary pollution, can reduce the toxicity of toxic organic compound in the water, be specially adapted to the organism of oxidation, organic clearance can be reached more than 99%, thereby improve drinking-water quality than difficult degradation.
