The extraction of underground resources has accelerated globally, in response to the demands of advancing technology and the rapidly growing population. The increase in drilling activities has caused an increase in environmental pollution problems caused by waste generated during drilling activities, namely drilling sludge and drilling wastewater. In this study, the treatability of wastewater generated during drilling operations in a basin, where an underground gas storage area was created, was investigated using an electrocoagulation (EC) process, using different electrode pairs. The removal efficiencies of the pollution parameters were determined using the response surface method. The wastewater parameters included different organic and inorganic pollutants, such as sodium, chloride, magnesium, and chemical oxygen demand (COD). The concentrations of sodium, chloride, and COD in drilling industry wastewater were found to be very high, at 128,567, 185,292, and 7500 mg/L, respectively. The data obtained in this study yielded a removal efficiency of approximately 65% and above. Sodium achieved the highest pollutant removal efficiency of 85% and above. The statistical values were interpreted for all the pollutants and the suitability of second-degree regression was observed.
为了满足先进技术的需求和迅速增长的人口需求，全球范围内地下资源的开采速度加快。钻探活动的增加导致了钻探活动中产生的废物（即钻探泥浆和钻探废水）所造成的环境污染问题增多。在本研究中，使用电凝聚（EC）工艺，采用不同的电极对，对一个创建了地下储气区的盆地钻探作业期间产生的废水的可处理性进行了研究。使用响应面法确定了污染参数的去除效率。废水参数包括不同的有机和无机污染物，如钠、氯、镁和化学需氧量（COD）。钻探行业废水中钠、氯和COD的浓度分别非常高，达到128567、185292和7500mg/L。本研究获得的数据产生了约65%及以上的去除效率。钠实现了最高的污染物去除效率，达到85%及以上。对所有污染物的统计值进行了解释，并观察到二次回归的适用性。
