Description
Summary:Planktonic algae when grown on a large scale on undiluted city sewage sharply accelerate the process of self-purification; this is expressed in faster initial lowering of the BOR, early termination of the anaerobic phase, the appearance of free oxygen, and in the accelerated onset of nitrification. The accumulation of a large quantity of organic substances synthesized by the algae in the composition of the bodies of the living cells is not reflected in the magnitude of the BOR. With the large-scale development of green algae in self- cleaning sewage the death rate of coliform bacterium is sharply increased. The construction of ponds filled with undiluted sewage is the simplest way to use green organisms as agents of self-purification; it draws attention also as an effective method of purification, especially applicable in regions with warm dry climates. Further study of the conditions favorable to the development of photosynthesizing planktonic organisms will allow setting up problems in the large-scale cultivation of algae as one of methods of utilizing sewage. In particular one should clarify the possibility of using algae grown on sewage to increase of the productivity of piscicultural ponds.
