Determination of The Optimal Dosage of Chemical Compounds in the Wastewater Treatment Process in Trang Bach Coal Mine: the Laboratory Scale

The pH index of Trang Bach coal mine wastewater ranges from 2,8 to 6, meanwhile, the content of Fe, Mn, and turbidity & suspendedsolids (TSS) are rather high and it is impossible to discharge the wastewater directly to the environment. In order to achievethe requirement of QCVN 40:2011/BTNMT standard – The national standard for industrial wastewater quality after treatment ofVietnam and other purposes, the wastewater need to be treated by several methods such as coagulation-flocculation or sedimentation.In this article, we intend to find the optimal dosages of chemical compounds for the TSS, pH, Fe and Mn treatment processfor Trang Bach coal mine wastewater in the laboratory modular.

Langmuir And Freundlich Models

In this study the removal of Mn (II) ions from wastewater using magnetite nanomaterial was investigated. Some factors influencing the wastewater treatment process were studied such as: treatment time, pH and the concentration of Mn (II) ions from wastewater. The results showed that using magnetite nanomaterial adsorbent lead to a wastewater treatment efficiency higher than 97%. Langmuir and Freundlich models were applied to describe the adsorption process. The correlation coefficients (R2) showed that both models are applicable to the experimental data obtained.

Wastewater Treatment Process

Naturally, microorganisms decompose the organic material existing in nature, both in the presence or absence of oxygen. The majority of materials such as poisonous chemical compounds, heavy metals, would prevent the treatment process from taking place, lead to the entry of these contaminants into the environment results in the emergence of numerous diseases. In the present study, using the TOXChem4.1 simulation model, attempts were made to simulate a wastewater treatment plant and then assess the dispersions of contaminants including 1,2-Dimethylnaphthalene, 1,3-Dinitropyrene, 1,6-Dimethylnaphthalene, 1,6-Dinitropyrene, and 17a-ethinylestradiol (EE2) in concentrations of a common scenario. The results of computer simulations showed that the EE2 contaminant is of the highest percentage of decomposition among others, due to its wider chemical structure. Consequently, it is clear that such contaminant is of the highest mass in the sludge exiting the treatment plant. In addition, the results of the simulations demonstrated that the highest volumes of gaseous pollutants take place in the modulation and initial sedimentation units.
