SUBSTANTIATION OF THE POSSIBILITY OF THE FLUID DISCHARGE IN THE SEWAGE SYSTEM, OBTAINED BY MEANS OF THE SOLID HOUSEHOLD WASTE DEHYDRATION IN THE PROCESS OF THE LOADING INTO THE DUST-CART

Abstract

In recent years the total area of the solid household waste landfills and sites has considerably increased, this threatens with the pollution of the environment with the harmful substances, including high toxic filtrate. The aim of the research is the substantiation by means of the regressive analysis of the possibility of the discharge in the sewage system the fluid, obtained by means of dehydration of the solid household waste during the loading in the dust-cart, that is actual scientific-engineering problem. The adequate regressive exponential dependence of the percentage ratio of the fluid, discharged from the solid household waste to actual productivity of the waste treatment plants of the sewage system on the population of the city has been obtained . Graphic dependence of the percentage ratio of the fluid, removed from the solid household waste, on actual productivity of the sewage treatment facilities system on the population of the city, that enables to illustrate the given dependence and show the sufficient convergence of the theoretical results with actual results. It is determined that in the cities with the population of at least 200 thousand people, there is a possibility to discharge in the sewage system the fluid, obtained as a result of solid household waste dehydration during the loading in the dust-cart as the percentage ratio of the fluid, removed from the solid household waste to actual productivity of the sewage treatment facilities does not exceed the scientifically grounded value of 0,2%. For the cities with the population of less than 200 thousand  people the dependence for the determination of the percentage volume of the possible safe dehydration of the solid household waste with the discharge of the fluid in the sewage system, that is one of the components for the solution of the problem of the creation scientific-engineering fundamentals for  the design of high efficient working organs of the mechanisms, intended  for the primary processing of solid household waste is suggested.
