Abstract:The Babylon Governorate is situated in the middle of Iraq. It covers an area of 5,315 km 2 and has 2,092,998 inhabitants distributed throughout its five major cities (Qadhaa). Presently, there is no landfill site in the governorate that meets the environmental criteria for the disposal of municipal and industrial waste. Consequently, GIS (geographic information system) and methods of multi-criteria decision making were used here to select the best sites in each city in the Babylon Governorate that would fulfil the environmental requirements. Two sites were chosen in each city. As the groundwater is very shallow in this area, the design should ensure against groundwater pollution by leachate from these sites. To avoid this problem, soil investigation was conducted at these sites so that the most suitable landfill design could be accomplished. The results of soil investigation in these sites include the soil profile, groundwater depth, chemical properties, allowable bearing capacity, Atterberg limits test results and material characteristics of the soil strata. From the research, it is believed that the best design is one that puts the landfill above ground.

“…The ammonia in water is one of the major environmental pollutants, which may cause the increase of chlorine consumption and oxygen demand, toxicity to fish, eutrofication and diseases like ethaemoglobinaemia hypertension and stomach cancer, as well as other serious environmental [3]. Specifically, ammonium has been identified as one of major toxicants to microorganisms in the treatment system [4], suggesting that pretreatment of ammonium is very important in reducing the concentration of NH 4 + [5][6]. In Vietnam, with the strong economic growth and seemly uncontrolled urbanization, the amount of solid waste generated has been increasing dramatically, especially in big cities such as Hanoi -the capital.…”

Abstract:Leachate from municipal landfills of the city is often contaminated heavily, especially for parameters such as organic components, heavy metals, microorganisms. However, leachate also contains amounts of valuable nutrients (e.g. N, P, K) which can be used for agriculture as fertilizers. Precipitated of N and P in the form of struvite (MgNH 4 PO 4 .6H 2 O) might be applied as a technique for removal a huge amount of N as well as P in wastewater. This study investigated the recovery ability of N, P in leachate from Nam Son municipal landfill of Hanoi city. Different pH values, anaerobic time and stoichiometric Mg 2+ : NH 4 + : PO 4 3-was tested to determine the optimal conditions for precipitating struvite. The effect of pH on the forming of struvite was between pH 9 to 11. The results showed that nutrients in landfill leachate could be recovered with the optimum pH around 9.5 and the optimum Mg 2+ : NH 4 + : PO 4 3-molar ratio as 1.15: 1: 1. With the anaerobic interval of 21 days, COD value in landfill leachate was decreased to 60%, the retrieval reached 80.6% for nitrogen and 82.7% for phosphorus. According to estimates, with the application of struvite precipitation technique, the average annual retrieval amount of NH 4 + and PO 4 3-can reach 263 tons and 25 tons, respectively.

Metal–Organic Interactions in Landfill Leachates and Associated Groundwaters

Landfills are important facilities for proper waste disposal in modern societies, but they can also be the potential source of environmental problems. These are mostly due to leachate spilling and releasing through surface and groundwaters. Because organic compounds are the most abundant constituents of these leachates and have a wealth of reactive functional groups, their interaction with metals is of utmost importance to understand the mobility and bioavailability of these metals in the environment. Metal–organic interaction is mostly characterized by complex formation and stability. Predicting metal–organic complex stability is, however, a difficult task, but the electronic configuration of metal cations may provide some insight on that problem based on the classification into hard‐ and soft‐sphere cations. On the other hand, landfill leachates are complex solutions where these interactions are likely to occur with a wide range of organic compounds, rendering individual interactions almost irrelevant. Besides, the number of cations experimentally studied in this particular environment is limited to Cu, Ni, Zn, Cd, Pb, and Cr. What has been shown is that, depending on the cation, they may be predominantly associated with colloidal and/or dissolved organic matter, in particular, forming chelates with the organic compounds, or forming inorganic complexes as well as insoluble solid phases.
