Background technique
With the problem of industrialized collection neutralizes the process of Population Urbanization, and water pollution is at that cannot avoid.Especially arrange
The pollution of nitrogen phosphorus in water, the harm become apparent is caused to environment.Current total polluted by nitrogen (nitrate in municipal wastewater treatment plant draining
The ratio that nitrogen accounts for total nitrogen weighs about minimizing technology 90%), exactly using anaerobe in the presence of carbon source, carries out the anti-nitre of heterotrophism
Change, the nitrate nitrogen in water is reduced to nitrogen, to leave water body, achievees the purpose that purification of water quality.
In order to promote the progress of this reaction, it is necessary to meet the condition of reaction, exactly there are enough carbon sources in draining, essence
For really, it is BOD:TN=3-5, is calculated according to average value 4, almost 90% sewage plant all suffers from carbon source deficiency, has no alternative, just
Artificial that carbon source is added, some addition sodium acetates, some addition methanol, What is more is added glucose, white sugar etc., causes resource
Significant wastage.In addition there are also technical risk, carbon source not enough will cause that water outlet total nitrogen is exceeded, and carbon source is excessive, will cause water outlet
COD is exceeded.In addition, generating a large amount of anaerobic sludges in reaction, needs periodically to backwash, workload is caused to increase.To sum up, currently
Heterotrophic denitrification technique, at high cost, complex process, cumbersome, risk is big.In view of this, developing a kind of completely new denitrogenation
Technique has very great meaning.

Sludge fragment in the process；Using structure of the invention can adding to avoid carbon source, reduce cost, equipment is simply not necessarily to add
Other optional equipments.
Preferably, the hybrid particles the preparation method comprises the following steps: by white lime, sodium thiosulfate and sulphur powder by weight 1:
1-4:1-3 mixing, obtains mixed-powder；Then add water into the mixed-powder, stirring keeps white lime abundant with carbon dioxide
Reaction generates calcium carbonate, is solidified into bulk, is then crushed, at graininess.
Preferably, the additive amount of the water is the 15-20% of the mixed-powder total weight.It can guarantee that white lime is abundant
Reaction, and can be poor to avoid excess moisture solidification effect.
Preferably, the filter layer with a thickness of 150-300mm.
Preferably, the purifying layer with a thickness of 250-350mm.
Preferably, the compactedness of hybrid particles is 360-420g/dm in the conversion zone3。
Preferably, treatment sewage is by the water flow linear velocity of the conversion zone in 1m/h or more.
Preferably, the water flow linear velocity that treatment sewage passes through the conversion zone is 1.5m/h.Guarantee sewage in filler
Residence time, improve purification efficiency.
The beneficial effects of the present invention are:
The present invention overcomes in traditional wastewater denitrification process the drawbacks of supplementary carbon source, without adding carbon source, save the cost, Er Qieshi
Sand, volcanic rock, white lime, sodium thiosulfate and sulphur powder are resourceful, and required device structure is simple, generally use upwards
The water intake mode of stream, and the speed of water flow by the size of hybrid particles is controlled and adjusts, so that guaranteeing water in filler
Residence time, wastewater purifying efficiency is good, and nitric efficiency is high.
