[Complex evaluation of self-purifying capacity of reservoir water].

Self-purification ability of water reservoirs is determined by a complex of indices: ratio of 5-day biochemical consumption of oxygen to full consumption of oxygen; chemical consumption of oxygen, content of dissolved oxygen; ratio of lactose-positive to faecal coli; total specific loading on the water object. Complex assessment of the intensity of self-purification makes it possible to characterize the process as sufficient, insufficient, low, very low.
