Abstract

The possibility of utilizing native waste from drinking water treatment as an absorbent material for petroleum products (motor oil grade 5W-40, diesel fuel, gasoline grade A-92) has been investigated. The mineralogical composition of the water treatment waste has been determined, according to the results, it primarily consists of quartz, calcite, sepiolite, anorthite, and gallwazite. Values of the maximum absorption capacity for the investigated petroleum products and the maximum water absorption have been established. To reduce water absorption properties, the native material have been modified by thermal treatment at a temperature of 550 °C, treatment with 5 % solutions of sulfuric acid and sodium hydroxide, as well as a 5 % solution of silicone fluid of the «Ecodom Bio» brand. Values of the maximum absorption capacity of the modified water treatment waste for petroleum products and water under static and dynamic conditions also have been determined. It has been revealed that thermal treatment contributes to achieving maximum absorption capacity values for both petroleum products and water absorption. It has been established that the minimal water absorption is observed in the sample of the investigated material treated with a siliconorganic fluid solution. Purification of liquids containing hydrocarbons at a concentration of 2 mg/dm3 in dynamic conditions has been carried out. Overall, it has been determined that the maximum solution purification is observed for motor oil, and the minimal one – for gasoline grade A-92.

水处理废料改性样品对石油产品的吸附作用

研究了利用饮用水处理产生的本地废物作为石油产品（5W-40 号机油、柴油、A-92 号汽油）吸附材料的可能性。根据研究结果，水处理废料的矿物成分主要由石英、方解石、海泡石、阳起石和五倍子石组成。确定了所调查石油产品的最大吸收能力值和最大吸水率。为了降低吸水性能，对原生材料进行了改良，包括在 550 °C 的温度下进行热处理、用 5% 的硫酸和氢氧化钠溶液以及 5% 的 "Ecodom Bio "品牌硅油溶液进行处理。此外，还确定了改良水处理废料在静态和动态条件下对石油产品和水的最大吸收能力值。结果表明，热处理有助于实现石油产品和水吸收的最大吸收能力值。经证实，用硅有机流体溶液处理过的调查材料样品的吸水性最小。在动态条件下，对浓度为 2 mg/dm3 的含碳氢化合物液体进行了净化。总的来说，机油的溶液净化效果最好，而 A-92 号汽油的净化效果最差。
