In order to strengthen the prevention and control of water pollution in rural rivers, it is necessary analyze causes detail, calculate pollutant reduction amount put forward comprehensive treatment measures. Aiming at small basin a county southwest Guangxi, this paper carried out improvement environment, including specifically investigation degree basin, calculating present load environment cap...
Pollution reduction related to combustion engines is considered be an important issue around the world. Hydrogen as additive energy has been utilized for alternative fuel since it need not require any modification. Particularly, a sustainable option diminishing petroleum dependence and air pollutant emissions. In this study, we investigated tailpipe emission with hydrogen addition different dri...
Background and Objective: Triclosan is one of the substances as anti-microbial that is used in many of these pharmaceutical products. This compound can affect human such as reduction of thyroid hormone levels, antibiotic resistant, and increasing skin cancer. This study evaluated the performance nanophotocatalysis process UV/Xe/TiO2-GO on triclosan removal from aqueous solutions. Materials and...
As a promising conjugated polymer, binary carbon nitride has attracted extensive attention as a metal-free and visible-light-responsive photocatalyst in the area of photon-involving purification of water and air. Herein, we report sulfur-doped polymeric carbon nitride microrods that are synthesized through thermal polymerization based on trithiocyanuric acid and melamine (TM) supramolecular agg...
Activated carbon adsorbing materials were installed in a number of showcases with heritage objects belonging to English Heritage. The reduction of acetic plus formic acid concentration in air, which could be achieved by the installation of the different adsorbing materials, was investigated. The concentrations of the gases were measured before and after installation of the adsorbers. The reduct...
In this paper, we assume that a professional pollutant treatment enterprise treats all of the pollutants emitted by multiple small and medium-sized enterprises (SMEs). In order to determine the treatment price, SMEs can bargain with the pollutant treatment enterprise individually, or through forming alliances. We propose a bargaining game model of centralized pollutant treatment to study how th...
