The Research Of Ammoniation Process Of Train Collection Bedpan Waste Water

Since long ago, passenger train always uses the straight platoon type restroom in our country, It's harmful to the environmental sanitation and the crowd's health along the route, causes the environmental pollution. Our country railroad implemented raised fast from 1996, started clear the highest speed 120～160km/h fast passenger train in three-main trunk lines different sectors, thus the straight platoon type restroom environmental pollution question changed prominently. With the implementation of type developmental strategy along with the railroad, the passenger train collection systematically is then listed as the one of the Ministry of Railways environmental protection "15" plan key attack projects.In order to protect the rail line environmental sanitation and crowd's health along the route, our country passenger train installs the collection bedpan gradually. Because of bedpan sewage pollutant density high, must be able satisfiedly to discharge there quest after processing, the railroad collection bedpan sewage processing oneself becomes the technology which our country railroad profession is imminent needs to solve.The present paper mainly through tires of the scene simulation test which the oxygen ammoniates, the analysis ammoniation process influence factor, understood joins the palms in greeting grasps NH3—N the change rule and the best operating mode, thus provides the basis for the actual operation movement. Obtains main conclusion as follows:(1)the best hydraulic retention time of Set the total Wastewater hydrazine train is 10-14 hours. The Ammonification time is associated with the component of Organic nitrogen; (2)By sequencing batch reactor under two different influent concentration of ammonia nitrogen in the determination of the law. We got to know which contains large amounts of organic nitrogen, into the sequencing batch reactor, ammonification and nitrification simultaneously. ABR to the influent water, water ammonia concentration increased with HRT , water ammonia concentration has been on a downward trend;(3)Two of anaerobic and aerobic processes under different circumstances hydrazine, come to a conclusion while containing large amount of organic nitrogen in waste water, that the effect aminate handles the sufficient anaerobism being in progress first to waste water to follow-up taking off a nitrogen is especially advantageous.
