Description

A kind of system for handling nitrogen-containing wastewater
Technical field
The utility model is related to environmental pollution process for comprehensively treating field, more particularly to it is a kind of handle nitrogen-containing wastewater be System.
Background technology
Ammonia nitrogen is one of pollutant main in China's water body, can result in body eutrophication, promotes algae reproduction, greatly Dissolved oxygen in amount consumption water body, causes organism in water is dead, water body fouls etc..Waste water containing ammonia nitrogen is mainly derived from coloured smelting The industries such as gold, chemical industry, biofermentation, ammonia nitrogen pollutant is mainly present in water with ammonium root, free state molecular forms in ammonia nitrogen waste water In.
In the prior art, it will usually nitrogen-containing wastewater is handled using single technique, technology common at present There are evaporating, concentrating and crystallizing method, distillation rectification method, stripping hair, chemical precipitation method, but single handling process is higher except cost Outside, the waste water containing finite concentration ammonia nitrogen can also be produced.
Publication No. CN102060406A Chinese patent application discloses a kind of method of blow-off method processing ammonia nitrogen waste water, Recovery by the ammonia-nitrogen desorption in waste water and is absorbed by packed tower.Publication No. CN1958471A Chinese patent application discloses A kind of processing method of ammonia nitrogen waste water, this method first have to add a large amount of alkali in waste water, to adjust pH value, to go through separation of solid and liquid Except the suspension in waste water and the sial ion and its compound of dissolving;Calcium ion generation calcium sulfate precipitation is added, through solid-liquid point From the acidic materials reduced in waste water;Carbanion generation precipitation of calcium carbonate is added, the calcium in waste water is removed through separation of solid and liquid Ion;PH value finally is adjusted between 9.5 ~ 13 with alkali again, is carried out stripping deamination and biochemical treatment, is that waste water reaches national discharge Standard.
The above method, it is required for that ammonia nitrogen waste water regulation is arrived into suitable pH using alkali, but when ammonia nitrogen concentration is higher, pH is not In the case of height, regulation pH can consume a large amount of alkali, so as to cause secondary pollution to water body.Therefore, a kind of use of research and development is needed badly In the processing system of the ammonia nitrogen of Coal Gas Washing Cycling Water.
The content of the invention
In order to solve the above technical problems, the utility model provides a kind of system for handling nitrogen-containing wastewater, including reaction Device and crystallization apparatus, the first pipeline is connected with the reaction unit, is connected between the reaction unit and the crystallization apparatus It is connected to the second pipeline.
Wherein, in addition to wash mill, the 3rd pipeline is connected between the wash mill and the reaction unit.
Wherein, in addition to wash mill and back extraction device, the wash mill and it is described back extraction device between connect There is the 4th pipeline, the 5th pipeline is connected between the back extraction device and the reaction unit.
Wherein, in addition to device is stripped, the 4th pipeline is connected between the wash mill and the back extraction device, The 5th pipeline is connected between the back extraction device and the reaction unit.
Wherein, pump and valve are respectively arranged with first pipeline and second pipeline.
Wherein, pump and valve are provided with the 3rd pipeline.
Wherein, pump and valve are respectively arranged with described the 4th pipeline and the 5th pipeline.
The beneficial effects of the utility model:
By it is provided by the utility model processing nitrogen-containing wastewater system, can in metal carbonate technology of threonates not It is respectively processed with waste water caused by link, when the ammonia nitrogen concentration in waste water is more than or equal to 20g/L, the second pipeline can be passed through Crystallization apparatus is directly entered, generates ammonium salt crystal.
When the ammonia nitrogen concentration in waste water is between 10g/L~20g/L, can be entered by the 3rd pipeline reaction unit be used for after Continuous dissolving ammonium carbonate or ammonium hydrogen carbonate, can also be by carbon unnecessary in waste water so as to can not only reduce deionized usage amount Acid ion further generates metal carbonate precipitate, while improves further the ammonia nitrogen concentration in waste water, so as to logical The second pipeline is crossed into crystallization apparatus generation ammonium salt crystal;Or first pass through the 4th pipeline and enter back extraction device, make organic phase In metal ion enter in waste water, then entered by the 5th pipeline in reaction unit, can not only make the gold in waste water Belong to the raw material that ion can again as generation metal carbonate, avoid directly discharge from causing water pollution, while can also make to give up Ammonia nitrogen in water is further improved in reaction unit, and ammonium salt crystal is generated so as to enter crystallization apparatus by the second pipeline.
When the ammonia nitrogen concentration in waste water is less than or equal to 10g/L, it can directly stay in wash mill and metal carbonate is sunk Shallow lake is cleaned, and is on the one hand reduced direct discharging of waste water and is caused water pollution, still further aspect also saves metal carbonate The usage amount of production process reclaimed water.
By system provided by the utility model, caused waste water in metal carbonate production process can be handled respectively, The ammonia nitrogen waste water directly discharge that not only avoid high concentration pollutes to water body, while can also effectively utilize the carbonic acid in waste water Radical ion and metal ion, make its raw material as production metal carbonate again.The system architecture is simple, easily operated, just In Industry Promotion.
