Abstract The study aimed to evaluate the ability of some terrestrial and aquatic plants for wastewater purification. Aquatic plants can remove pollutants from wastewater by consuming and accumulating various contaminants in different parts of plants. Different aquatic and terrestrial plants (Rosa sinensis, Typha latifolia, Ocimm bacilicum, Azolla pinnata, and Salvinia molesta) which have the ability to decrease water pollution were utilized in this study. The capability of five different species of plants was investigated by measuring chemical oxygen demand (COD), biological oxygen demand (BOD), electrical conductivity (EC), total dissolved solids (TDS), and pH of the medium. In this research, some aquatic… More >

Abstract With the development of urbanization in China, the problem of garbage disposal has become increasingly serious. Among the existing waste treatment technologies, pyrolysis is an emerging treatment technology, which has obvious advantages in terms of reduction and secondary pollution. It has good development prospects. This article first compares the advantages and disadvantages of various existing waste treatment technologies, and proposes an organization method that combines thermogravimetric analysis, kinetic analysis, tube furnace experiments, and domestic waste pyrolysis and low-calorie heat the decomposed gases burn together. Urban garbage is one of the main pollution sources of modern urban environmental pollution in the… More >
