Journal Title: Бюллетень науки и практики - Year 2018, Vol 4, Issue 5
Abstract
The problem of utilization of waste treatment facilities every year becomes more acute for many urban, rural settlements in Russia. Over the years near their territories, numerous sludge–infested sludge plots, tailing dumps, dumps, and quarries were formed. Their presence significantly affects the living conditions of the population, environmental safety in the regions. The purpose of this paper is a comparative description of the method for disinfecting sewage fecal waste and a device for utilization of sludge from sewage treatment plants. Precipitation formed in the process of wastewater treatment in the form of excess silt, although they are of value due to the content of a number of organic components, but do not have a permanent composition. This, in turn, requires certain compliance with the processing conditions for use as fertilizers in obtaining agricultural products. In sediments, heavy metals are often found. Getting into the soil, they can adversely affect plants, animals and humans, the natural environment in general. Meanwhile, the introduction of various composts into the soil or production on their basis is one of the ways to solve the problem of getting rid of the huge amount of waste that accumulates in populated areas. The soil is enriched with nutrient macro– and microelements and organic substances. Utilization of precipitation in the form of fertilizers in agriculture will reduce the costs of mineral fertilizers to 600–1000 rubles/ha. To regulate the introduction of sewage sludge into the soil, taking into account the requirements of environmental safety, it is necessary to introduce a system of legislative acts.
