在工業(yè)污水領域,生物制劑也是比較科學的技術(shù)手段,其所呈現(xiàn)的降解效果是比較顯著的,也能夠讓污水處理工藝得到合理優(yōu)化,同時也能夠保證水體的生態(tài)環(huán)境受到保護。一般情況下,在利用該技術(shù)進行污水處理的過程中,需要在細菌的類型上進行規(guī)范選擇,合理利用有益細菌,并在此基礎上與水體中的有機物發(fā)生一定的生物反應,從而達到良好的分解處理效果。同時,在投入微生物菌株期間,還可以選擇相關的消化酶,并將其有效地作用到水體環(huán)境當中,促進微生物在水體中的綜合分解效能,也能夠?qū)⒂袡C物進行有效地轉(zhuǎn)化,能夠讓水環(huán)境呈現(xiàn)出良好的凈化效果,也能夠有效地去除工業(yè)污水中的異味。
In the field of industrial wastewater, biological agents is also a more scientific technical means, its degradation effect is more significant, it can also make the wastewater treatment process reasonable optimization, but also can ensure that the ecological environment of the water body is protected. In general, in the process of using this technology for wastewater treatment, it is necessary to select the type of bacteria, make rational use of beneficial bacteria, and on this basis, have a certain biological reaction with the organic matter in the water, so as to achieve good decomposition treatment effect. At the same time, during the period of microbial strain input, relevant digestive enzymes can also be selected and effectively applied to the water environment to promote the comprehensive decomposition efficiency of microorganisms in the water, and effectively transform the organic matter, which can make the water environment present a good purification effect and effectively remove the odor in industrial sewage.
(三)高級氧化處理技術(shù)
(3) Advanced oxidation treatment technology
該技術(shù)簡稱AOPs,在降低污水毒性方面所具有的功能價值比較顯著[2]。其工作原理具體體現(xiàn)在,經(jīng)過一系列的反應,能夠產(chǎn)生羥基,并借助其所具有的氧化功能,對水體中的污染物進行有效地干預,從而達到有機物有效分解的目的。該技術(shù)所蘊含的類型具有一定的多樣性,具體包括Fenton氧化法,臭氧氧化法等,在針對工業(yè)污水進行作業(yè)處理的過程中,則可以根據(jù)實際情況進行規(guī)范選擇。
This technology is called AOPs for short, which has significant function value in reducing the toxicity of wastewater [2]. Its working principle is embodied in that after a series of reactions, hydroxyl can be produced, and with the help of its oxidation function, the pollutants in water can be effectively intervened, so as to achieve the purpose of effective decomposition of organic matter. The types contained in this technology have certain diversity, including Fenton oxidation, ozone oxidation, etc. in the process of industrial wastewater treatment, it can be selected according to the actual situation.
(四)樹脂交換法
(4) Resin exchange method
該技術(shù)的處理和應用效果也是比較顯著的,尤其是在針對重金屬的處理方面,所具有的功能價值比較顯著,也能夠讓水體的顏色更加的透徹、干凈,有效地控制污水的毒性。因此,在今后在針對工業(yè)污水進行有效處理的過程中,相關部門需要從實際情況出發(fā),確定工業(yè)污水類型,在此基礎上科學選擇深度處理技術(shù),從而達到水體凈化的效果,或者,可以將多種處理技術(shù)進行有效結(jié)合,構(gòu)建完善性、綜合性的深度處理技術(shù)體系,從而保證所呈現(xiàn)的功能效果更加突出。
The treatment and application effect of this technology is also significant, especially in the treatment of heavy metals, which has significant functional value, and can make the color of water more thorough and clean, and effectively control the toxicity of sewage. Therefore, in the process of effective treatment of industrial sewage in the future, relevant departments need to determine the type of industrial sewage from the actual situation, and scientifically select advanced treatment technology on this basis, so as to achieve the effect of water purification. Or, a variety of treatment technologies can be effectively combined to build a perfect and comprehensive advanced treatment technology system, So as to ensure that the presented function effect is more prominent.
