摘要
对煤矿采掘水的化学和物理浓度用于网箱渔业的可行性进行了研究。这项研究旨在分析已形成湖泊的煤矿采掘水的化学参数(NH3、pH 值、铜和铁)和物理参数(溶解氧、温度和浊度)的浓度条件。样品在分析前通过添加浓硝酸进行制备。使用原子吸收分光光度计分析铜和铁的浓度,使用紫外可见分光光度计分析氨的浓度,使用滴定法分析溶解氧的浓度,使用浊度计分析浊度,使用温度计分析温度,使用 pH 计分析 pH 值。研究结果表明,原煤矿采掘区湖水的物理参数为 pH、温度、溶解氧、NH3 和浊度,由于尚未通过指定为养殖淡水鱼网箱的质量标准,因此适合养殖淡水鱼。煤矿采掘废水中重金属 Cu 的浓度已经超过了淡水鱼养殖的质量标准,而金属 Fe 的浓度则没有超过规定的质量标准。研究分析了原采煤池水样中重金属的平均浓度,即 Cu(0.166;0.278;0.284 mg/L)和 Fe(0.020;0.029;0.023 mg/kg)。
Feasibility study of concentration of chemical and physical parameters in excavated water coal mining as a cage fishing destination
A research was carried out on the feasibility of chemical and physical concentrations in coal mine excavation water for use in cage fisheries. This research aims to analyze the concentration conditions of chemical parameters (NH3, pH, Cu and Fe) and physical parameters (DO, temperature and turbidity) in water originating from coal excavations which are already in the form of lakes. Samples were prepared before analysis by adding concentrated nitric acid. Analysis of Cu and Fe concentrations was carried out using an Atomic Absorption Spectrophotometer (AAS), ammonia using a UV-Vis Spectrophotometer, DO concentrations were analyzed using the titration method, turbidity analysis using a nephelometer, temperature using a thermometer and pH using a pH meter. From the research results, it was found that the physical parameters of lake water from former coal mine excavations were pH, temperature, DO, NH3 and turbidity is suitable because it has not yet passed the quality standards for designation as a cage for cultivating freshwater fish. The concentration of the heavy metal Cu in coal excavation water has exceeded the quality standards set for cultivating freshwater fish and the metal concentration Fe has not exceeded the quality standards set. Research analysis of the average concentrations of heavy metals in water samples from former coal mining pools, namely Cu (0.166; 0.278; 0.284 mg/L), and Fe (0.020; 0.029; 0.023 mg/kg).
