CALCULATION OF THE SYSTEM OF WASTEWATER TREATMENT FROM OIL PRODUCTS AT THE RAILWAY STATION
This article describes the processes of preparation, steaming, degassing of tanks and the subsequent stages of wastewater treatment, because railway transport there is a need to release wastewater from polluting oil products, used flotation units. The technological process of preparing tanks for filling provides for two main types of processing. After passing through these facilities, wastewater has the following characteristics: the amount of wastewater: 1297 m3 / day (approximately 54 m3 / h), oil products - 95 mg / dm3, suspended substances - 50 mg / dm3, aromatic hydrocarbons -100 mg / dm3 and so on. To decrease pollution to the required levels, it is necessary to install additional wastewater treatment facilities. Switching to drainless systems or systems with a minimum discharge of wastewater can be accomplished by reusing wastewater and replacing water cooling with air. With the transition of a number of industries to anhydrous technological processes, the formation of wastewater is excluded.
