4) effluent quality is good, and is stable
Electromechanical equipment quantity is few, and the probability that produces fault is low.
5) running cost is low
The biochemical combined reactor of sewage disposal has merged self purification of water body and two functions of artificial aeration's intensive treatment, has integrated multinomial advanced reactor, need not handle mud, dirt for many years, and therefore, processing cost has only the 1/3----1/2 of popular response device.
6) reactor is succinct, operational administrative is simple, strong shock resistance.
7) flexible operation, processing power are adjustable in a big way.
8) perfect adaptation of realization sewage disposal and landscape construction makes peripheral land price increment;
Breaking the normal procedure, (air that is produced and mud pollute in sewage work, directly or indirectly reduce peripheral Land values) fixed pattern, the biochemical combined reactor of sewage disposal can build up ecological park, both can build ecoscape, improve the ecological environment, can be dissolved in the urban afforestation again, make peripheral land price increment.The shape of the biochemical combined reactor of sewage disposal can according to view require and topographical condition definite, can be rectangle, trapezoidal, circular, semicircle, Polygons, irregular polygon or other shapes, adopt a kind at least, its cross section can be for trapezoidal.
