Specific implementation mode
Be described further below technical scheme of the present invention, but claimed range be not limited to it is described.
As shown in Figure 1, a kind of disinfection nitrogen rejection facility for handling landfill leachate, including liquid storing barrel 1, reactive tank 2, receipts
Collect slot 3, medicament addition device 4, the level height of the liquid storing barrel 1 is higher than the level height of reactive tank 2,1 He of liquid storing barrel
Reactive tank 2 forms waterway circulating by pipeline and circulating pump A7, and the reactive tank 2 is connect by air pump 9 with collecting tank 3, described
Medicament addition device 4 is connect with the top of reactive tank 2.
Landfill leachate water quality is complicated and changeable, and pH value is between 4-9, and COD is within the scope of 2000-62000mg/L, BOD5
From 60-45000mg/L, when being handled, if the water quality of landfill leachate is deteriorated suddenly, the sewage that is easy to cause that treated
Water quality is not still up to standard, and the present apparatus is mounted on the rear end of conventional garbage percolate treatment plant, passes through wastewater influent before sewage discharge
Mouth 5 enters in liquid storing barrel 1, and the level height of liquid storing barrel 1 is higher than the level height of reactive tank 2, and sewage flows into reaction by gravity
In slot 2, medicament addition device 4 controls the additive amount of sodium hypochlorite according to the amount of sewage and the concentration of pollutant, using secondary
The strong oxidizing property of sodium chlorate before sewage discharge, then carries out once sterilizing, and sodium hypochlorite can effectively reduce the Cod of sewage
Value, ammonia nitrogen value, coloration, make its indices meet the emission request of GB16889-2008, are drawn back sewage using circulating pump A7
In liquid storing barrel 1, waterway circulating is formed, sodium hypochlorite can be made to be uniformly dispersed in sewage in cyclic process, in liquid storing barrel 1
Sewage after indices meet the requirements, is discharged online by disinfection.
Sodium hypochlorite is easy to be influenced by light, heat and heavy metal ion in use, is easy to decomposite chlorine, is
It prevents chlorine to be diffused into air, air pump 9 is equipped on reactive tank 2, make to form negative pressure in reactive tank 2, and chlorine is pumped into
1% to 3% sodium hydroxide solution is housed, and by circulating pump B8 constantly from collecting tank 3 in collecting tank 3, in collecting tank 3
Portion sprays into collecting tank 3, reacts with chlorine, generates sodium chloride and sodium hypochlorite, sodium hypochlorite under alkaline condition steady
Qualitative height can prevent sodium hypochlorite from decomposing again, after the concentration of sodium hypochlorite is stablized, open valve 10, will be in collecting tank 3
Solution be introduced into reactive tank 2, carry out recycling use, the production cost of enterprise can be reduced.
