The removal of high-concentration C.I. acid orange 7 (AO7) in aqueous solution by the prepared iron/copper (Fe/Cu) bimetallic particles and zerovalent iron (ZVI) was investigated thoroughly. Fe/Cu were planting Cu on surface Fe. Experimental results confirmed superiority for degradation AO7 solution. Under optimal conditions ([Fe/Cu]0 = 40 g·L–1, [AO7]0 1000 mmol·L–1, initial pH 6.5, TMLCu 0.62 g Cu/g Fe), concentration chemical oxygen demand (COD) total organic carbon (TOC) efficiencies...
Heterogeneous electro-Fenton is one of the promising technologies to degrade refractory organic phosphonates. In this work, CoNWs@CoAl-LDHs/Fe3O4 and CoNPs@CoAl-LDHs/Fe3O4 were successfully synthesized by a co-precipitation method applied 1-hydroxyethane-1,1-diphosphonic acid (HEDP) glyphosate (PMG) via an process. The results indicated that removal rate HEDP (100 mg L-1) PMG increased from 62.09% 95.31% 82.45% 100%, respectively. system could remove 70.03% nearly 100% within 2 hours at pH...
Different types of materials were used as catalyst carriers to enhance the degradation salicylic acid in heterogeneous electro-Fenton system. During experiments, activated carbon, carbon felt and cloth selected based materials, sodium alginate, chitosan polyvinyl alcohol chosen polymer matrix, foam metal included zinc foam, iron nickel (NF). The changes surface structure morphology above studied, combined with effects on NF was best carrier for system, Ni Fe3O4 had synergistic effect...
Cd(ii) adsorption onto Fe(ii) modified Layered double hydroxide-graphene oxide (LDH-GO@Fe(ii)) was investigated using batch experiments. With the modification of Fe(ii), LDH-GO maintained its structure, while species formed non-crystalline iron clusters on surface LDH/GO. A kinetics study indicated that obeyed a pseudo-second-order rate law. The equilibrium data were fitted well with Langmuir isotherm model. maximum capacity LDH-GO@Fe(ii)10 28.98 mg g-1, higher those pure and...
The electro-Fenton (EF) process was applied to treat mother liquor of gas field wastewater (ML-GFW). Fe-Fe electrodes were used and H2O2 added the EF system. Effect initial pH on chemical oxygen demand (COD) removal efficiency, specific electrical energy consumption (SEEC), electrode plate (SEPC) organic matter mechanism investigated. results showed that COD efficiency reached maximum (71.9%) at 3 after reaction for h. Besides, considering with SEEC SEPC, also best choice, which 4.7 kW h...
A lab-scale anoxic-oxic moving bed biofilm reactor (A/O-MBBR) was used to treat simulated nitrogenous wastewater.Transition of compounds and total nitrogen (TN) removal performance were studied under extreme hydraulic retention time 8 h.The optimal NH 4 + -N TN achieved with dissolved oxygen (DO) concentration 5.4 mg/L in the oxic reactor, which 72% 34% influent urea around 30 50 mg/L.Polysaccharide concentration, protein PS/PN fluctuated significantly variation DO zone, 31.8 mg/g VSS, 7.1...
Most of the materials studied as catalysts in electro-Fenton system are variants iron oxide or hydroxide. However, iron-based often exhibit weak catalytic capabilities under neutral and alkaline conditions. In this work, we synthesized three cobalt based bimetallic oxides, Co2CuOx, Co2AlOx, Co2NiOx, using hydrothermal method evaluated them for heterogeneous to remove 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP) Methylisothiazolinone [2-methyl-4-isothiazolin-3-one] (MIT). Co2NiOx has...
Effect of C/N ratio and aeration rate on performance continuously operated internal circulation membrane bioreactor (ICMBR) was investigated thoroughly using synthetic domestic wastewater. The results show that COD total nitrogen (TN) removal efficiencies were improved with the increase under certain conditions (T = 25 °C, MLSS 10 g/L, 0.15 m3/h, influent NH3-N concentration 20 mg/L, -N 100 HRT 12 h). Meanwhile, a steady ammonia (AN) (~80%) obtained when increased from 2:1 to 6:1....
Shale gas fracturing flowback fluid contains various degradation difficulty organic compounds after hydraulic fracturing. A hybrid treatment method was developed for treating and produced water (FPW) using pre-treatment (NaClO) followed by the expanded granular sludge bed (EGSB) moving biofilm reactor (MBBR). Gas chromatography–mass spectrometry (GC-MS) employed to detect composition in FPW, pre-treated EGSB MBBR effluent. FPW had high chemical oxygen demand (COD) (3278 mg/L) majority of...
Different metal cation (Co2+, Fe2+, La3+, and Zn2+)-doped layered double hydroxides (LDHs), yielded CoMgAl-LDH, FeMgAl-LDH, MgAlLa-LDH, ZnMgAl-LDH, respectively. The four LDHs synthesized from same molar ratio of MII:MIII had different adsorption capacities toward Cr(VI) fluoride (F−). Single competitive kinetic isotherms Cr (VI) F− were studied. For each LDH, the capacity was higher compared with in single adsorption, which confirmed that more selective for adsorption. In CoMgAl-LDH...
The competitive adsorption of phosphate and nitrate from aqueous solution on calcined Mg-Al layered double hydroxides (Mg-Al CLDHs) were investigated.Experiments carried out as a function adsorbent dosage, contact time, initial pH temperature.The processes followed by the pseudo second-order first-order kinetics, respectively.The X-ray diffraction patterns (XRD) showed structural reconstruction during sorption, unchanged d-spacing d 003 indicated mainly adsorbed surface near-edge...
