According to this result it can be seen that the obtained serosity of pulping process of the present utility model for ammonia-nitrogen content in treatment of acidic wastewater gained water far below ammonia-nitrogen content in the slurrying processing method of normal sands drainage, ammonia nitrogen removal frank improves more than 50%.
What deserves to be explained is, the slurrying that the carbide slag pulping device that above-mentioned comparative example 1 is based in this utility model carries out, if in common pulping device, lack ring type aeration tube, its ammonia-nitrogen content will be above detected 132.6mg/L, embodies the carbide slag pulping device of the present utility model superior function in removing ammonia-nitrogen content further.
In conjunction with actual production process, the displacement of pulping process of the present utility model is analyzed:
1, certain titanium dioxide sewage treatment process processes sewage 8000m day by day3, wherein H2SO4Content about 4%, FeSO4 content about 0.5%, supply dry carbide slag Ca (OH)2Content is about 50%；
2, the course of reaction of carbide slag and acid waste water is:
H2SO4+Ca(OH)2——CaSO4+2H2OFeSO4+Ca(OH)2——CaSO4+Fe(OH)2
987415274
According to above-mentioned formula, the odd-numbered day processes 8000m3Sewage need to consume the dry carbide quantity of slag:
8000 × 0.04 × 74 ÷ 98 ÷ 0.5+8000 × 0.005 × 74 ÷ 152 ÷ 0.5=522t；
3, carbide slag need to be made Ca (OH) by sewage disposal2Content is about the carbide slag slurries of 10% needs the water consumption to be:
522 × 0.5 ÷ 0.1-522=2088m3
4, can obtain drawing a conclusion according to above result of calculation:
With sand leaching water carbide slag slurries total displacement every day for 8000+2088=10088m3；
To produce remaining hot water carbide slag slurries total displacement every day for 8000-2088=5912m3；
Odd-numbered day water consumption, produces remaining hot water carbide slag slurries relatively sand leaching water carbide slag slurries and uses sand leaching water 2088m less3；
Odd-numbered day total displacement, produces remaining hot water carbide slag slurries relatively sand leaching water carbide slag slurries and discharges less:
(5912-10088) ÷ 10088=41.4%, by relative analysis it can be seen that pulping process of the present utility model need not provide sand leaching water when slurrying, decreases total displacement.
This utility model utilizes temperature, pH, the aeration combined influence to material NH_3-N treating, recycle heat energy and water resource, improved energy utilization rate, and reduce total water discharge capacity, reduce the TAN being brought into neutralized system by carbide slag, greatly alleviate Environmental Inputs and ambient pressure.
