The technical solution of the utility model is achieved in that synthetic ammonia Waste Water Containing Sulfur purification system, comprise hot tub, hot water pump, automatic regulating valve, cooling tower, water cooling pond, water supply pump, monobasic cleaner, chemicals dosing plant, water coolant uses system and horizontal sedimentation tank, the water side of described hot tub successively pipeline connects hot water pump, automatic regulating valve, cooling tower, water cooling pond, water supply pump and water coolant use system, described automatic regulating valve the first water outlet connects cooling tower, the second water outlet is the top that purifies liquid-inlet pipe, the end that purifies liquid-inlet pipe connects the feed-water end of monobasic cleaner side, the middle part of described purification liquid-inlet pipe connects chemicals dosing plant, the supernatant liquid outlet of described monobasic cleaner upper end connects water cooling pond, and bottom feed-water end connects the end that cleans liquid-inlet pipe, and the top of described cleaning liquid-inlet pipe is on the pipeline between water supply pump and water coolant use system.
As to further improvement of the utility model, the bottom feed-water end of described monobasic cleaner is three inlet channels, and middle inlet channel is main road water-in, and both sides are bypass water-in, on described three inlet channels, all establish arm, after three arm series connection, connect horizontal sedimentation tank.
As to further improvement of the utility model, on the bottom inlet channel of described monobasic cleaner one side bypass, connect the top of flushing pollution discharge pipe, the end of flushing pollution discharge pipe connects hot tub; Described lateral inflow end is two pipelines, connects respectively opposite side bypass and the main road of monobasic cleaner.
As to further improvement of the utility model, described automatic regulating valve is flow control T-valve, and 80%～90% liquid is sent into the first outlet, and 10%～20% liquid is sent into the second outlet.
The utility model adopts after said structure, by automatic regulating valve, 10%～20% water coolant is sent into monobasic cleaner and carry out circularly purifying, intrasystem sewage is remained on fouling, the nonvolatile steady state of sulfide do not occur, greatly reduced dosing, reduced cost; In time blowdown is also reclaimed, and in system, sewage is difficult for occurring side reaction, and material after reclaiming is recycling; Unlike the prior art, by the shunting of automatic regulating valve and the recovery of flushing pollution discharge pipe, make system enter sulfide concentration in the liquid of cooling tower lower, even fluid surface does not produce sulfide foam when temperature drift, sulfide is non-volatile, can not cause environmental air pollution; The utility model works very well simple in structure, while being particularly suitable for Chemical Manufacture, synthetic ammonia Waste Water Containing Sulfur purifies and uses.
