Abstract
The utility model discloses an aeration denitrification device. The aeration denitrification device comprises a separating tower and an ammonia gas absorption tower, and is characterized in that the separating tower is provided with a water inlet, a water outlet, charging holes and air outlets, and an aeration plate is arranged in the separating tower; the aeration plate comprises a main aeration pipe and branch aeration pipes, the branch aeration pipes are uniformly distributed on the main aeration pipe, the air inlet of the aeration plate is connected with an air blower, and the air outlet of the separating tower is connected with the ammonia gas absorption tower through an induced draft fan. The aeration denitrification device disclosed by the utility model has the advantages that the air and waste water are contacted in a uniform and largest area manner, the rate of reaction between the waste water and a denitrification agent is increased, the waste water handling capacity is large, the ammonia gas discharging speed is high, and the denitrification efficiency is high.
Description
Technical field
The utility model relates to a kind of aeration nitrogen rejection facility.
Background technology
Domestic adopted nitrogen-containing wastewater treatment process mainly contains following several at present: traditional biological denitrogenation, ammonia blow-off method, ion exchange method, break point chlorination, magnesium ammonium phosphate method.Traditional biological denitride technology is by ammonification, nitrated, denitrification and assimilation completes, the technical maturity of traditional biological denitrogenation, denitrification effect is better, but exist technical process long, take up an area many, often must additional carbons, energy consumption greatly, high in cost of production shortcoming, ammonia blow-off method is divided into air stripping method and steam blow-off method, method technique is simple, effect stability, strong adaptability, but energy consumption is large, there is secondary pollution.Ion exchange method is actually the exchangable ion that utilizes on insoluble ionic compound and other same sex ion NH in solution
4 +there is permutoid reaction, thereby by the NH in waste water
4 +be adsorbed on securely ion-exchanger surface, reach the object of removal of ammonia and nitrogen, but efficiency be low, resin demand is large, difficult for regeneration, and working cost is high, has the shortcomings such as secondary pollution.Break point chlorination is to add excessive chlorine or clorox, makes ammonia nitrogen in waste water be oxidized to the chemical denitrification process of nitrogen, and the method efficiency can reach 90%-100%, treatment effect is stable, be not subject to Water Temperature, but working cost is high, by product chloramines and chlorinatedorganic can cause secondary pollution, magnesium ammonium phosphate method technique is simple, easy to operate, and reaction is fast, can fully reclaim ammonia and realize waste water reclaiming, but the precipitation dosing that the method is used is excessive, causes processing cost higher, need further to be researched and developed.No matter use which kind of method in the past to process nitrogen-containing wastewater, all unavoidable working cost is high at present, and the ammonia nitrogen waste water after processing is all difficult to be up to state standards.
Summary of the invention
The purpose of this utility model is just to provide a kind of simple in structure, working efficiency is high, production cost is low aeration nitrogen rejection facility.
Aeration nitrogen rejection facility of the present utility model, comprise knockout tower, ammonia absorption tower, it is characterized in that, knockout tower is provided with water-in, water outlet, charging opening and air outlet, aeration board is equipped with in its inside, and aeration board comprises main aeration tube and an aeration tube, and an aeration tube is evenly distributed on main aeration tube, the inlet mouth of aeration board connects gas blower, and the air outlet of knockout tower is connected with ammonia absorption tower by induced draft fan.
Aeration nitrogen rejection facility of the present utility model, starts gas blower, and waste water is sent into from water-in, during to certain liquid level, toward charging opening, adds medicament, and it is fully reacted, and the ammonia producing after denitrogenation is sent into ammonia absorption tower through induced draft fan and carried out ammonia recovery.
Aeration nitrogen rejection facility of the present utility model, air and waste water evenly and maximum area contact, accelerated the speed of reaction of waste water and denitrfying agent, wastewater treatment capacity greatly, ammonia emission speed is fast, nitric efficiency is high.
