Abstract
The utility model discloses an ammonia nitrogen blows system of taking off, include pH equalizing basin, elevator pump and blow and take off the tower, connect a shell and tube heat exchanger between pH equalizing basin and the elevator pump, the elevator pump passes through the pipe connection blow the water inlet that takes off the tower, blowing the top of the tower portion of taking off and being equipped with the gas outlet, blow tuo tanei and from top to bottom be equipped with demister, water distributor and clean shot packing layer in proper order, blow and take off the tower lower extreme and be equipped with the delivery port, the bottom is equipped with the air inlet, the air inlet is connected with the air -blower through the admission line, blow the gas outlet of taking off top of the tower portion and pass through a pipe connection vapour and liquid separator. The utility model discloses a waste water preheats waste water through the heat exchanger behind the pH equalizing basin again, and then the pump goes into to blow to take off to blow in the tower and take off, has improved greatly to blow and has taken off efficiency, the ammonia that blows the mid -career student gets into vapour and liquid separator through blowing the gas outlet of taking off top of the tower portion, and the ammonia of after -separating can be used to recycle, and the water of after -separating can continue to be used for circulation system, has improved the utilization ratio.
Description
Technical field
The utility model relates to a kind of Sewage treatment systems, especially a kind of ammonia nitrogen stripping system.
Background technology
A large amount of discharges of ammonia nitrogen, not only cause the phenomenons such as the pollution of water surrounding, body eutrophication and water body generation red tide, and in Industrial Wastewater Treatment and reuse project, cause the breeding of microorganism in watering equipment and form biofouling, blocking pipe and watering equipment, affect heat exchange.High-concentration ammonia nitrogenous wastewater wide material sources, complicated component, strong toxicity, large to environmental hazard, intractability is also large, and the NO3-N and NO2-N of oxidized generation also can affect the hydrobiont even health of the mankind.
At present, the physico-chemical process of process high-concentration ammonia nitrogenous wastewater is a lot, mainly contain air stripping method, steam stripped method, break point chlorination method, ion exchange method, chemical precipitation method etc., more be blow-off method, but there is a lot of defect in existing stripping process, the high or fluctuation of service of the low cost of removal efficiency.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide high, the economic environmental protection of a kind of ammonia-nitrogen removal rate to avoid the ammonia nitrogen stripping system of secondary pollution.
For achieving the above object, the technical solution adopted in the utility model is: a kind of ammonia nitrogen stripping system, comprise pH regulator pond, lift pump and stripping tower, a shell and tube heat exchanger is connected between described pH regulator pond and lift pump, described lift pump connects the water-in of described stripping tower by pipeline, described stripping tower top is provided with air outlet, from top to bottom scum dredger is provided with successively in stripping tower, water distributor and hollow ball packing layer, stripping tower lower end is provided with water outlet, bottom is provided with inlet mouth, described inlet mouth is connected with gas blower by intake ducting, the air outlet at described stripping tower top connects a gas-liquid separator by pipeline.
Described water distributor is made up of comb in upright arrangement, and described comb is provided with single water distributing pore, and be provided with volution nozzle under water distributing pore, water distributing pore not easily blocks, and can also ensure atomizing effect.
Described intake ducting is provided with constant pressure arrangement, and described constant pressure arrangement comprises pressure transmitter and magnetic valve, for controlling the gaseous tension entered in stripping tower.
The water outlet of described gas-liquid separator is connected on pH regulator pond by pipeline, makes the water after separation again get back to the recycle system, reuses.
The beneficial effects of the utility model are: waste water behind pH regulator pond, then carries out preheating through interchanger to waste water, and then pump in stripping tower and carry out stripping, substantially increase stripping efficiency; The ammonia that stripping produces enters gas-liquid separator through the air outlet at stripping tower top, and the ammonia after separation can be used for recycling, and the water after separation can continue on for the recycle system, improves utilization ratio.
