In waste water, the composition of ammonia nitrogen is mainly with the presence of two kinds: the ammonia nitrogen (e.g., ammonium sulfate, ammonium chloride etc.) that the ammonia nitrogen of ammonia form formation and inorganic ammonia are formed.At present, main denitrogenation method has bioanalysis (nitration denitrification), break point chlorination, air stripping stripping and ion exchange etc..Wherein blow-off method is owing to apparatus and process is simple, practicality is used widely more by force.Many defects such as but legacy equipment exists treatment effeciency to be reduced, and operating cost is high.
[utility model content]
The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of three grades of sewage-treatment plants based on Venturi effect.
In order to solve the problem existing for background technology, a kind of three grades of sewage-treatment plants based on Venturi effect of the present utility model, it comprises housing, one-level dividing plate, two grades of dividing plates, outlet valve, bottom outlet, one-level gas outlet, one-level water pump, two grades of water pumps, tertiary effluent pump, one-level venturi Self inhaling device, two grades of venturi Self inhaling devices, three grades of venturi Self inhaling devices, water inlet, outlet, two grades of gas outlets, three grades of gas outlets, packing layer, packing support plates；Enclosure interior arranges one-level dividing plate and inner space is separated into three sections by two grades of dividing plates, water inlet and outlet are arranged on housing side, one-level gas outlet is arranged on case top, two grades of gas outlets and three grades of gas outlets are arranged on housing side, one-level water pump, one-level venturi Self inhaling device and water inlet are sequentially connected with, two grades of water pumps, two grades of venturi Self inhaling devices and water inlet are sequentially connected with, tertiary effluent pump, three grades of venturi Self inhaling devices and water inlet are sequentially connected with, in housing, bottom arranges packing support plate, it it is packing layer on packing support plate, on the outlet of bottom, outlet valve is set.
As preferably, the ratio of height to diameter of described housing is between 5:1 to 6:1.
As preferably, the polytetrafluoroethylmaterial material coating of employing inside of described housing.
As preferably, described packing support plate gathers sieve aperture.
As preferably, described packing layer uses activated carbon to do adsorbent.
This utility model has the beneficial effect that the mixing certainly utilizing Venturi effect to achieve dirty water and air, greatly improves sewage treating efficiency, and treating capacity is big, can effectively remove the ammonia nitrogen in sewage, it is to avoid body eutrophication problem.
