“…************************************************** The above three kinds of WW treatment technological processes were studied initially by using a different specific MW-enhanced WW treatment method in each case[58, 61,69,81,87]. However, these processes are universally adaptable; in other words, after modification they can still be applied when other kinds of MW-enhanced WW treatment methods are used.…”

“…However, these processes are universally adaptable; in other words, after modification they can still be applied when other kinds of MW-enhanced WW treatment methods are used. An understanding of the common ground of the WW treatment technological processes has the potential benefit of improving the understanding of the MW non-thermal effect because this can allow comparison of data from different studies to some extent.The reaction system inFigure 4A(batch mode) was used for the MICD process initially[81,87]. However, it could still be used directly in other kinds of MW-enhanced WW treatment methods such as the MW-oxidant, MW-Fenton, MW-Fenton-like, and MICO (except for MW-CWAO process) processes.…”

“…However, investigations into the degradation of carbofuran by pyrite are depleting to date and the available information is of limited use in elucidating mechanistic pathways of carbofuran degradation. In contrast, there is substantial information on the degradation of carbofuran by photochemical [16], chemical [2,3], pyrolytic [21] and biological [22] methods and in most of them are routinely used in advanced oxidation processes of water treatment. In pyrolytic degradation, carbofuran has disintegrated into 83 low molecular mass fragments, viz.…”

HighlightsCarbofuran (2,2-dimethyl-2,3-dihydrobenzofuran-7-al-methylcarbamate) was partially degraded by natural pyrite Degradative pathways of carbofuran were suggested Pyrite showed a potential as a geo-catalyst in pollution control Abstract This work provides new insight into the degradation of 2,2-dimethyl-2,3-dihydrobenzofuran-7-yl-methylcarbamate (hereafter carbofuran)by natural pyrite as a function of pH and adsorbent loading. In the presence of tert-butyl alcohol i.e. OH • scavenger, the degradation efficiency of carbofuran was almost stopped. In acidic solutions (pH < 5) the degradation kinetics was pseudo first order in carbofuran as [ ] .[ ] observed d carbofuran k carbofuran dt − = − . The dependence of k observed on [FeS 2 ] was given as k observed =k 0 +[FeS 2 ].k 1 where k 0 = 1.16 x 10 -7 h -1 and k 1 = 0.137 h -1 .The elucidation of precise steps of carbofuran degradation by pyrite has yet to be solved.

Nonylphenol (NP) is a common endocrine disrupting compound that is hazardous to the bio-environment. Microwave peroxide oxidation (MPO) is an energy-efficient technology that can destroy toxic organic compounds in hazardous waste. The objective of this article is to study the rapid degradation of NP in wastewater sludge discharged from a detergent manufactory using MPO with HNO 3 . The major finding is that nearly all NP, over 95% in the sludge, can be degraded in 3 min at a temperature of 423 K using the MPO treatment. The results obtained in this work imply that MPO provides the potential to degrade NP and lower its toxicity. Significant NP degradation efficiency was achieved, showing sufficient toxic level reduction for further sludge reutilization. A useful correlation between degradation efficiency and treatment conditions is proposed based on the experimental data obtained in this study. For engineering applications, the necessary minimum treatment time is solved using a graphic illustration method, by which the minimum treatment time is obtained if the desired degradation efficiency and treatment temperature are known. The treatment time and temperature effects are also discussed in this article.
