Abstract

A key task in alcohol distilleries is the effective treatment of biomethanated spent wash after biogas recovery. This colored washwater exhibits low biodegradability index (BI?<?0.2), high chemical oxygen demand (30,000?<?COD?<?40,000?mg/L), and recalcitrance to aerobic treatment. In this work, pretreatment of biomethanated distillery wastewater by Fenton oxidation was proposed for improved biogas recovery. The effects of temperature, solution pH, and H2O2 dosage on the efficacy of the oxidation process were studied. Using ferrous sulfate catalyst (36?mg/L) for diluted wastewater (BOD5?=?81; COD?=?400?mg/L), 54% reduction in COD was achieved within 1?h in acidic medium (pH?=?3) at ambient temperature (T?=?30?°C). Post-oxidation, the BI value improved (0.33). After subsequent adsorption over activated carbon (loading 5%) for 1?h, COD reduction (70%), and BI value (0.43) improved further. Upon anaerobic treatment with 1% acclimatized biomass, 1?Nm3 of biogas (47% CH4) was additionally formed per m3 of treated wastewater; without pretreatment, this value was 0.9?Nm3 (just 11% CH4). Lastly, aerobic treatment was performed and the results were encouraging: BI?=?0.51 and COD reduction?=?94%. Many oxidation products were identified and first-order kinetic plots were made to describe COD conversion kinetics. In this way, useful insight on a plausible technique for valorization of biomethanated washwater was provided.  相似文献

In the present work, poly (vinylidene fluoride-co-hexafluoropropylene) [P(VDF-HFP)] and various amounts of NASICON-type LiZr1.5Sn0.5(PO4)3 (LZSP) as the active filler were used to fabricate composite solid electrolytes (CSEs) by solution-casting method and their structural and electrochemical behaviour were studied. The X-ray diffraction (XRD) data showed the compatibility of the rhombohedral LZSP with P(VDF-HFP). A uniform distribution of ceramic particles in the polymer was observed from scanning electron microscopy (SEM) images and energy X-ray dispersive maps. The addition of 15% wt. ceramic filler to the polymer matrix enhanced the room temperature ionic conductivity (σ ∼ 2.87 × 10−5 S/cm), lithium-ion transference number (tLi+ ∼ 0.55), and electrochemical stability window (∼4.87 V). The reversibility and endurance of lithium-ion conduction across the composite electrolyte at various current densities were confirmed through galvanostatic charge-discharge measurements on a symmetric lithium cell for more than 500 h. A full cell fabricated using a commercial grade LiMn2O4 cathode and the optimized CSE electrolyte showed excellent rate performance at room temperature. The cell delivered a discharge capacity of 105 mAh/g with a nominal voltage of 4.0 V and retained 93% of its initial capacity after 100 cycles at a current density of 0.1 mA/cm2.  相似文献

Conclusions With the incorporation of finely milled magnesite into the batch of chrome-magnesite there are significant improvements in the sinterability of the brick, and increases in strength after firing. Changing the setting scheme for the products on the kiln cars yields more uniform distribution of the temperature over the height of the kiln, improves the firing conditions, and reduces the loss. The roofs of the furnaces also have a longer life.Translated from Ogneupory, No. 2, pp. 5–6, February, 1969.  相似文献

The separation of ice from ice slurries is the final step in the process of freeze concentration, where wash column can be employed. Phenomena found in washing an ice bed, such as channeling, viscous fingering, clogging, liquid entrainment, and permeability were studied in an experimental wash column. The appropriate operating conditions that lead to a successful washing were proposed in this paper.  相似文献

It is well known that orientation can produce, at a minimum, an order of magnitude improvement in physical properties of low cost plastic resins. A unique, large-scale, commercial rolling mill process for continuous orientation of plastic sheet has been developed, A number of oriented materials have been commercially produced by this rolling mill process with a wide variety of physical properties attained. This has resulted in large volume sales of many interesting commercial products. Over the last thirty years, numerous researchers have conducted studies to evaluate the theoretical aspects of the rolling process, and the resultant properties. Most commercial oriented products are of relatively small cross sectional size such as fibers and film. The process reported herein produces heavy cross section oriented sheet. A new class of high strength thermoplastic materials is now available for design engineers to use. Long-term strength properties are often 10 to 100 times better than with unoriented thermoplastics.  相似文献
