Abstract
In this paper, the issue of clearing the territory of snow with the use of snow melting units is being considered. The operating principle of the snow-melting stations is based on sewage heat) melting the snow collected in the snow collection chambers. Snow melt water mixed with wastewater is discharged into the collectors and transported to have a full treatment cycle at the wastewater treatment plant. Three problems of urban snow-melting process are considered. The solution of three problems is proposed: compiling a list of signs of mandatory snow removal zones; the allocation of the main zones corresponding to the proposed features; method of determining the amount of snow that is mandatory for export from the territory of the zone.
Highlights
Snow, which is collected from streets, squares and roads, until recently was discharged into the nearest ponds without treatment, since it was not attributed to the waste of the settlement, as is done in most parts of the world [1], but to conventionally pure natural precipitation
Snow belongs to the category of waste of the 4th class of danger [2], the solution of the problems associated with its disposal is a serious link in the chain of measures to clean up city streets
The urban area of compulsory export of snow can be divided into three zones by possible to place stationary snow melting units
Summary
Snow, which is collected from streets, squares and roads, until recently was discharged into the nearest ponds without treatment, since it was not attributed to the waste of the settlement, as is done in most parts of the world [1], but to conventionally pure natural precipitation. More recently, the processing of snow is quite harmless and does not aggravate the work of treatment plants [3].
