The analysis of the general physical and chemical indicators and the maintenance of heavy metals of sewage of a bioenergy complex is carried out. It is established that the sedimentation rate of suspended particles in wastewater depends on the location of filtration fields with wastewater from the source of contamination. At the source, there is a maximum excess of the number of suspended particles with a minimum deposition rate. In all wastewater samples, the indicators of chemical and biological oxygen consumption exceeded the permissible standards by three orders of magnitude for reservoirs for recreational water use and those located within the settlements. Thus, this water cannot be discharged into any natural water basin and requires additional purification from organic matter. Also for this water, the use of biological treatment methods without additional chemicals is ineffective. The presence of a complex of macro- and microelements in wastewater in combination with a high content of organic matter (humus and sulfonic acids) may be the basis for their use as raw material for fertilizer production.

Soil, itself means Soul of Infinite Life. Soil is the naturally occurring unconsolidated or loose covering on the earth’s surface. Physical properties depend upon the amount, size, shape, arrangement, and mineral composition of soil particles. It also depends on the organic matter content and pore spaces. Chemical properties depend on the Inorganic and organic matter present in the soil. Soils are the essential components of the environment and foundation resources for nearly all types of land use, besides being the most important component of sustainable agriculture. Therefore, assessment of soil quality and its direction of change with time is an ideal and primary indicator of sustainable agricultural land management. Soil quality indicators refer to measurable soil attributes that influence the capacity of a soil to function, within the limits imposed by the ecosystem, to preserve biological productivity and environmental quality and promote plant, animal and human health. The present study is to assess these soil attributes such as physical and chemical properties season-wise.

Oily Wastewater Treatment

Oily sewage is one of the wastes produced in the oil industry production process and its quantity has been increasing year by year, which influences the environment and human health severely. Electric flocculation method is one of the wide application electrochemical treatment technologies for the oily wastewater treatment at home and abroad, which has higher efficiency than other technologies at the aspect of the organic pollutants degradation. A simulative experiment device dealing with heavy oil sewage by the electric flocculation method has been designed in this paper. The mechanism of the electric flocculation method in removing organic matter of the heavy oil sewage by analyzing the change of the composition and content of the organic matter in water samples before and after the process of the electric flocculation has been studied. Research results show: the carbon/tin dioxide electrode is better than the carbon/ ruthenium dioxide electrode in removing organic matter; most alkanes matters in the oily wastewater have been removed in the dispersing oil form by the electric flocculation; as the current density increases, the types and quantity of the response organic matter can be improved while types of the new synthetic organics increase. At the same time, this paper provides a theory support in specific optimization of the electricity flocculation flotation in oily wastewater treatment technology and process.
