Utilize the different character of the free ammonia content of ammonia nitrogen under different PH and differing temps, the present invention has realized pure physical treatment art breading high concentration ammonia nitrogen sewage, when guaranteeing treatment effect, improving processing efficiency, realized saving land, the energy-conservation and purpose that reduces discharging.
The present invention has the following advantages:
(1) sewage is not heated, only air is heated, with respect to water-to-water heat exchanger, the investment of airheater is much smaller, and has realized saving land and saves the purpose of investment;
(2) energy consumption in treating processes only is created in blower fan, airheater and water pump, and energy consumption is low, has realized purpose of energy saving;
(3) in treating processes, do not consume steam, realized purpose of energy saving;
(4) the high-efficiency cyclone gas pipe makes liquid in the sewage, gas phase finish twice separation, effectively reduces liquid-gas ratio, has realized purpose of energy saving;
(5) stripping and the secondary separation of sewage in the ammonia-nitrogen desorption treatment unit has the function that reduces COD;
(6) ammonia-nitrogen desorption is provided with the multistage stripping device that a plurality of one-tenth distribute up and down in handling, and has effectively avoided single-stage stripping device to handle the not generation of phenomenon up to standard;
(7) every grade of stripping device all has air outlet, has effectively avoided the generation of the ammonia secondary pollution phenomenon that gone out by stripping;
(8) this treatment system is carried out selective use for the air of discharge outlet, and the gas that meets discharging standards is directly discharged, and the gas that ammonia nitrogen concentration is higher is recycled.
In sum, the present invention focuses on a plurality of processing units in the treatment system, not only having improved efficient and the treatment effect of sewage disposal, also realized saving the purpose of capital construction cost and working cost, is a kind of Sewage treatment systems with very high practical value.
