Influence of Small Water Streams on Water Disposal Processes on the Example of OAO Solombalsky TSBK
Summary
Influence of streams and small rivers on pollution of a zone of mixing of runoffs of the Solombalsky pulp-and-paper plant and the ostiary water of the river of Northern Dvina by organic substances identified according to the parameter of chemical oxygen demand (COD) is considered. Presence of very high values of COD (100–403 mg/l) in water of streams with strongly boggy watersheds is revealed. Obvious domination of natural organics over its volumes in the enterprise’s runoffs is shown. When controlling the discharge of wastewater of pulp-and-papers plants into water objects it is recommended to take into account polluting substances of natural origin coming to the site of their dilution through small waterways (small rivers, streams and drainage ditches).
