The Effectiveness of Some Coal-Based Mineral Compositions in the Decontamination and Environmental Protection of the Small Urban Rivers’ Watery

Abstract

The effectiveness of the “T”-brand coal processing sludge, technical pyrocarbon, and their mixture as adsorbents for the decontamination of drainage water from organic pollutants has been investigated. The contaminated water samples were collected from the ordinary car filling/service station’s drainage system and then treated with the adsorbents. Water absorbance and chemical oxygen demand (COD) were controlled as the water quality and decontamination effectiveness parameters. A 4:1 mixture of coal refinery sludge and technical pyrocarbon was used as the most efficient adsorbent for mixed petrochemical and mechanical pollution agents. It has been found that this composition effectively decontaminates water from mixed organic pollutants. The water cleaning cartridges filled with this composition of adsorbents showed high decontamination performance eliminating about 85 % of petrochemical water pollution agents. This performance does not degrade much, and a 4 kg adsorbent load should be sufficient to treat an amount of wastewater formed at the car filling station for at least one month.
