Abstract:

Acid mine drainage is a main environmental problem linked to coal and sulfide ore mining. Its treatment usually involves alkalinization and subsequent precipitation and immobilization of the dissolved species. Rainfalls over stockpiles can cause a very similar phenomenon. This work aimed to study the effluents from such a leaching process in steam-coal stockpiles Brazilian coal with a high pyrite content was used. The effluents have been chemically characterized. Effluent clarification by aggregation and settling in an attempt to simultaneously deplete heavy metal content was studied. Settling

Abstract:

Abstract The importance of coal carbonization industries is evolving with great interest from the national point of view. In coke ovens, naturally found coal is converted to coke suitable for metallurgical industries. Enormous quantities of liquid effluents produced contain suspended solids high in COD, BOD, phenols, ammonia, and other toxic substances disposed into the water bodies without proper treatment contamination of the aquatic ecosystem. A large coke plant of Steel Authority of India Limited (SAIL) at Rourkela Steel Plant (RSP) has been surveyed for this purpose, and the impact of its

Abstract:

Mining is an ancient occupation, long recognized as being arduous and liable to injury and disease. Coal mining carried dangers from exposure to noise, heat, and airborne dusts, causing many associated diseases. Respiratory diseases caused by coal mine dust are pneumoconiosis, chronic bronchitis, and emphysema. The process of coal mining involves the discharge of huge amount of effluent into the surface water. Effluent from coal mine contains high load of TSS, TDS, calcium carbonate and heavy metals accumulates in water, soil, sediment and living organism. Coal mining has long been established

Abstract:

The technical and economic analysis of supercritical water oxidation (SCWO) and biochemical process for Lurgi coal gasification wastewater (LCGW) treatment were carried out. The findings include the analysis of flow sheet, effluent quality and operation cost of the two processes. Studies show that the SCWO process is more simply and easier to control than the biochemical process. The effluent treated with SCWO process could reach national discharge standard I (GB 8978-1996) without other pretreatment and advanced processes, and could gain 2.3 yuan RMB/t(LCGW). While the operation cost of bioch

Abstract:

The effective treatment of membrane concentrate is a major technical challenge faced by the new coal chemical industry. In this study, a supported perovskite catalyst LaCoO3/X was prepared by a sol–impregnation two-step method. The feasibility of the supported perovskite catalyst LaCoO3/X in the UV-catalytic wet hydrogen peroxide oxidation (UV-CWPO) system for the purification of concentrated liquid of coal chemical wastewater was investigated. The effects of catalyst support, calcination temperature, calcination time, and re-use time on catalytic performance were investigated by batch experim

Abstract:

Polycyclic aromatic hydrocarbons (PAHs), 33 methylated PAHs (Me-PAHs), and 14 nitrated PAHs (NPAHs) were measured in wastewater treatment plants (WWTPs) to study the removal efficiency of these compounds through the WWTPs, as well as their source appointment and potential risk in the effluent. The concentrations of ∑PAHs, ∑Me-PAHs, and ∑NPAHs were 2.01–8.91, 23.0–102, and 6.21–171 µg/L in the influent, and 0.17–1.37, 0.06–0.41 and 0.01–2.41 µg/L in the effluent, respectively. Simple Treat 4.0 and meta-regression methods were applied to calculate the removal efficiencies (REs) for the 63 PAHs a

Abstract:

Abstract Land application of anaerobic digestion (AD) effluent as a fertilizer is desirable for nutrient recycle, but often supplies excess phosphorus (P), which contributes to surface water eutrophication. Reducing the P content in AD effluent using calcium treatment prior to land application is a potential strategy for improving effluent disposability. In order to solve the problems of low phosphorus removal efficiency and high operating cost in wastewaters, this study took flue gas desulphurization (FGD) gypsum, a by-product of coal-fired power plants, as a low-cost calcium source, and comb

Abstract:

Screen bowl centrifugation process is widely used for fine coal dewatering due to its relatively low cost, high capacity of providing low-moisture content product as well as relative ease of operation and maintenance. However, screen bowl centrifuge tends to lose a significant amount of ultrafine clean coal to the main effluent and screen-drain streams. This study aims at obtaining a better understanding of the parameter main effects and interaction effects with an ultimate goal of improving the dewatering performance of a screen bowl centrifuge.

Abstract:

Malaysia generated 156,665 gigawatt-hours (GWh) of electricity in 2016 of which the biggest share of 48.4% was sourced from coal and coke. Malaysia coal consumption was met by 90.5% of imported coal due to high demand from the power sector. Malaysia also has a vast biomass resource that is currently under-utilised for electricity generation. This paper reviews the potential of oil palm residues and municipal solid waste (MSW) for alternative coal replacement employing hydrothermal treatment (HTT). In 2017, about 51.19 million tonnes (Mt) of oil palm waste was available with 888.33 peta-joule (

two roadways in adjacent working face of Baode Mine may have the risk of water inrush at the same time, so it is necessary to construct long borehole to cover the roadway excavation. On the basis of the hydrogeological conditions of the mine, the safe water insulation thickness and water inrush coefficient of coal seam No .8 are calculated. The results show that the water inrush coefficient is 0.035-0.037 MPa/m, which is less than the critical value 0.06 MPa/m and the bottom plate has no sudden water hazard. In the construction of No .10 coal seam, the directional long borehole is used to dete
