Abstract
The invention discloses the double de- techniques of sewage treatment plant's sulphur autotrophy nitrogen sulphur: in the water outlet of sewage treatment plant, contain nitrate nitrogen, in the biogas that Sludge Digestion in Wastewater Treatment Plant generates, contain hydrogen sulfide, water outlet is mixed into (and basic species are added) with biogas, then hydrogen sulfide is dissolved in water outlet, and biogas realizes desulfurization；And dissolved in the water outlet of hydrogen sulfide, it is reacted through over cure autotrophic denitrification, water outlet realizes denitrogenation.
Description
Technical field
The present invention relates to a kind of sewage disposal system more particularly to a kind of denitrification treatment process of sewage.
Background technique
Effluent index as defined in A standard in DB11/890-2012, the overwhelming majority have had reached the finger of earth's surface Group III water
It marks (earth's surface Group III water is the standard of potable water source district second protection zone), still, total nitrogen index is 10mg/L.
One of total nitrogen, and the factor for causing water eutrophication.That is: although having spent very big generation in Beijing
Valence makes the effluent index of sewage treatment plant, and the overwhelming majority has reached the standard of earth's surface Group III water, but since total nitrogen index is bad,
Therefore, the threat of water eutrophication is still very big.
In sewage disposal plant effluent, the substance of total nitrogen, mostly nitrate nitrogen are formed.Due to carbon source, nitrogen to remove
These last nitrate nitrogens, the cost is relatively high, and --- --- needs Xiang Shuizhong to add reducing agent.Usually methanol or reduced form sulfur-bearing
Substance.
In sewage treatment plant, it is generally fitted provided with sludge digestion technique unit, in the biogas that sludge digestion generates, contains
Hydrogen sulfide is a kind of harmful substance, it is necessary to first remove, biogas could be used.And hydrogen sulfide is exactly that a kind of reduced form contains
Sulfur material.Hydrogen sulfide is dissolved in sewage disposal plant effluent, the reaction of sulphur autotrophic denitrification is recycled, then nitrogen can be achieved, the double of sulphur take off
It removes.The exactly such thinking of this patent.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of double de- techniques of sewage treatment plant's sulphur autotrophy nitrogen sulphur, features
It is: runs according to the following steps:
Step 1, the biogas that the secondary clarifier effluent of sewage treatment plant and sludge digestion are generated, in a closed reaction
Alkaline matter is added when necessary in mixing in device；
Step 2 exports gas respectively and water, derived gas leaves system, into subsequent technique；
Step 3, derived water carry out denitrification reaction into sulphur autotrophic denitrification reaction tank；
Step 4, the water after denitrogenation, discharge.
Compared with existing treatment process, a kind of beneficial effect of the de- techniques of sewage treatment plant's sulphur autotrophy nitrogen sulphur pair is: benefit
The substance contained with sewage treatment plant itself carries out denitrogenation and desulphurization reaction, had not only eliminated the pollution of nitrogen, sulphur, but also saved medicine
Agent expense.
Specific embodiment
Embodiment:
The present embodiment is Pekinese's municipal sewage plant, which executes Beijing's provincial standard (in DB11/890-2012
A standard: COD < 20, BOD < 4, NH3-N < 1, TN < 10).From index, COD, BOD index are very low, through it is too long when
Between aeration, the composition of TN, mainly nitrate nitrogen.The factory is furnished with sludge digestion technique unit, and therefore, which has selected sulphur autotrophy
The double de- techniques of nitrogen sulphur, operating procedure are as follows:
Step 1, the biogas that the secondary clarifier effluent of sewage treatment plant and sludge digestion are generated, in a closed reaction
Mixing in device, meanwhile, powdered lime is added；Since the main ingredient of biogas is CH4、CO2And H2S, and the water pole of secondary settling tank
Greatly, therefore, whole H2S and partial CO2It dissolves in water, makes water in acidity, and the powdered lime being added just neutralizes acidity,
And generate CaCO3, so that whole H in biogas2S and partial CO2It is removed；
Step 2 exports gas respectively and water, derived gas leaves system, into subsequent technique；
Step 3, derived water carry out denitrification reaction into sulphur autotrophic denitrification reaction tank；
Step 4, the water after denitrogenation, discharge.
Above embodiments are only exemplary embodiment of the present invention, are not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can within the spirit and scope of the present invention make respectively the present invention
Kind modification or equivalent replacement, this modification or equivalent replacement also should be regarded as being within the scope of the present invention.
Claims (1)
1. a kind of double de- techniques of sewage treatment plant's sulphur autotrophy nitrogen sulphur, it is characterised in that: run according to the following steps:
Step 1, the biogas that the secondary clarifier effluent of sewage treatment plant and sludge digestion are generated, in a closed reactor
Alkaline matter is added when necessary in mixing；
Step 2 exports gas respectively and water, derived gas leaves system, into subsequent technique；
Step 3, derived water carry out denitrification reaction into sulphur autotrophic denitrification reaction tank；
Step 4, the water after denitrogenation, discharge.
