Description
Technical field
The invention belongs to environmental protection and technical field of new energies, more particularly to a kind of two-stage mineralized waste reactor combination dress
Put.
Background technology
With the continuous improvement of fast-developing and people's consumptive power of Chinese national economy, the yield of house refuse is not yet
It is disconnected to increase.China's domestic waste yield has reached 1.51 hundred million tons within 2012, and China's municipal refuse total amount is up to 1.8 within 2013
Hundred million tons, municipal refuse accounts for the 30% of national rubbish total amount.The main method of China's domestic rubbish disposal is sanitary landfills, this side
Method can produce a large amount of percolates.Percolate is a kind of high concentrated organic wastewater of complicated component, ammonia high with organic loading
The features such as nitrogen and content of beary metal are higher, later stage biodegradability is poor for landfill, water quality and water are changed greatly.Traditional percolate
Processing method has that investment cost is high, processing cost is high, and later stage operation energy consumption is big, complex technical process, big, system of taking up an area place
The problems such as being easily hit difficult with effluent quality up to standard, thus the safe handling of percolate is the current a great problem for facing.
Aged refuse reactor processes percolate, and not only high treating effect, sufficiently utilizes changing waste into resources, reaches
To the purpose of the treatment of wastes with processes of wastes against one another, and processing cost is low, and technological process and operational management are simple and convenient, with the life of preferable environment
State meaning and economic benefit.
Since the nineties in last century, some scholars have carried out some and have ground to aged refuse reactor treatment percolate
Study carefully work.Forefathers' research all shows that mineralized waste bed has good treatment effect to ammonia nitrogen, but but fails to solve water outlet nitre state
Nitrogen content problem high, causes nitrogen removal rate not high, and one of reason is that denitrification process carbon source is not enough, into anoxic zone
Percolate carbon-nitrogen ratio with anaerobic zone is low, hinders the denitrification of nitrate nitrogen.
The content of the invention
It is an object of the invention to provide a kind of two-stage mineralized waste reactor combined apparatus.

Change diffusion in waste layer cylinder, gauze is wrapped up in outside ventilation duct, prevent mineralized waste from blocking air vent；Mineralized waste reactor top
Add a cover, covered funnel, for water filling, valve is set between funnel and lid, base adds one layer of PVC board of uniform cloth hole, for equal
Even water distribution；Mineralized waste reactor loads gravel layer, mineralized waste layer and inclined-plane gravel layer respectively from top to bottom, uniform cloth hole
Swash plate supporting oblique surface gravel layer, three temp probes uniformly imbed mineralized waste layer, for determining heap body temperature.
Described two mineralized waste reactors are respectively first order mineralized waste reactor and the reaction of second level mineralized waste
Device, first order mineralized waste reactor is synchronous nitration and denitrification reactor, and its aeration rate is 0.2 ~ 3.0 m3/(m3·d)；The
Two grades of mineralized waste reactors are denitrification reactor or the reactor based on denitrification, and its aeration rate is 0 ~ 0.4 m3/
(m3·d)；Aeration position is arranged on any between reactor bottom to reactor head 1/3rd as the case may be
Position；Influent load is 30 ~ 70 L/ (m3·d)；The water inlet frequency is 1 ~ 2 time/d；The particle diameter of the mineralized waste is 4 ~ 10mm.
Two-stage mineralized waste reactor Combined Treatment of the invention is percolated liquid device, is gone in first order mineralized waste reactor
On the basis of except part total nitrogen, denitrification is supplemented by the way that certain proportion stoste percolate is injected into second level mineralized waste reactor
Carbon source, farthest realizes denitrification denitrogenation, improves nitrogen removal rate；And percolate is processed using mineralized waste, is realized
The treatment of wastes with processes of wastes against one another.
