Embodiment 1

[0033] see figure 1 , a device for treating wastewater by electron beam irradiation, mainly comprising a wastewater collection pool 1, an irradiation treatment pool 3 and a clean water pool 4 connected in sequence through a water delivery pipe, and an electron accelerator 5 is arranged directly above the irradiation treatment pool 3 . see figure 2 , each water delivery pipe is installed with water pump 6 respectively, the water inlet 7 of each water delivery pipe is located at the top of each pond side wall, the water outlet 8 of each water delivery pipe is located at the bottom of each pond side wall, and the top of each pool is provided with can open and close The pool cover9. An irradiation preparation pool 2 is added between the waste water collection pool 1 and the irradiation treatment pool 3, and the irradiation preparation pool 2 can be used as a buffer pool between the waste water collection pool 1 and the irradiation treatment pool 3, and can also play a role in s...

Embodiment 2

[0045] The technical solution of this embodiment is basically the same as that of Embodiment 1, the difference is that:

[0046] In this embodiment, this wastewater treatment process device can treat pharmaceutical fine chemical production wastewater such as ethyl benzoyl acrylate and 3,5-dihydroxytoluene. For wastewater containing pesticide residues, the accelerator accelerates the energy of electrons The electron beam intensity of the electron accelerator 5 is 0.6mA, the treatment time is 40 seconds, the removal rate is above 90%, and the chromaticity is reduced to close to 0. In this embodiment, the irradiation technology is used to effectively degrade the pharmaceutical intermediates in the wastewater, reduce the level of organic pollutants and the content of total organic carbon in the water body, and meet the emission standards. The treatment method greatly reduces the treatment cost and improves the economic benefit. In addition, the treatment effect of this technology...

Embodiment 3

[0048] The technical solutions of this embodiment are basically the same as those of Embodiment 1 and Embodiment 2, except that:

[0049] In this embodiment, this wastewater treatment process flow device can purify industrial circulating water. For example, for wastewater containing phthalates, the energy of the accelerated electrons of the electron accelerator 5 is 0.1MeV, and the electron beam current intensity is 0.1mA, the treatment time is 20 seconds, and the removal rate reaches over 98%. In this embodiment, effective treatment of the circulating water is achieved by developing effective treatment technologies for related pollutants. Among them, the degradation rate of phenolic substances reaches more than 95%, which meets the requirements of recycling and solves the key problems of enterprises. At present, with the help of the research group, 150,000 tons of circulating water have been effectively treated.

[0050] Radiation technology is generally carried out under n...

Abstract

The invention discloses a device for treating waste water by an electron beam irradiation method, which comprises a waste water collecting pool, an irradiation preparing pool, an irradiation treating pool, and a clear water pool which are communicated by water conveying pipes orderly; an electron accelerator is disposed right above the irradiation treating pool; each water conveying pipe is equipped with a water pump; a sinking-mode irradiation flowing water trough is disposed in the center of a pool cover of the irradiation treating pool; uniformly-arranged flowing water trough water inlets are disposed at the bottom surface of the irradiation flowing water trough; waste water to be treated spews upwards and flows into the irradiation flowing water trough from the flowing water trough water inlets; water-distributing pipelines are disposed below the irradiation flowing water trough; flowing water trough water outlets are uniformly arranged at the trough bottom of the irradiation treating pool; the flowing water trough water outlets are communicated with the irradiation treating pool; switch valves are mounted on the flowing water trough water outlets; when the switch valves are open, water treated by the electron beam irradiation method flows into the irradiation treating pool. The invention has high treatment efficiency for industrial organic waste water, can effectively solve the problem of industrial water pollution, has a simple structure, is safe and reliable, and has low treatment cost.

Description

technical field [0001] The invention relates to a device for treating waste water, in particular to a device for treating waste water by electron beam irradiation. The waste water treatment process flow device is suitable for irradiating industrially polluted waste water to degrade it. Background technique [0002] At present, high-concentration toxic organic wastewater in chemical, pharmaceutical and other industries is one of the main reasons for the aggravation of water pollution in my country. The common feature of this kind of wastewater is that it is difficult to degrade in the environment, exists stably for a long time, and has bioaccumulation, which seriously affects human health. Therefore, the treatment of high-concentration refractory organic wastewater is a research hotspot in water treatment technology and has important application value. [0003] At present, there are a variety of treatment technologies for high-concentration refractory wastewater, including c...
