Description

A kind of regulation and control municipal wastewater pipeline sulphur conversion system in situ and its operation method
Technical field
The invention belongs to technical field of sewage, and in particular to a kind of regulation and control municipal wastewater pipeline sulphur conversion system in situ And its operation method.
Background technology
Municipal wastewater pipeline corrodes the economic loss brought every year to the whole world and is up to multi-million dollar, wherein hydrogen sulfide （H2S）Corrosion has become a most important origin cause of formation of sewage conduct " short-lived " caused by release.Meanwhile sewage conduct H2S is released Put that the poisoning of initiation is of common occurrence, the life and health to municipal drainage facility maintenance worker brings great threat.With Urbanization in China is accelerated, municipal drainage pipe network during " 12 "（Rainwater and sewage conduct）Overall length reaches 510,000 kilometers, Meanwhile municipal drainage pipe network gradually will include underground pipe gallery during " 13 ", therefore, municipal wastewater pipeline is studied H2S controls meet national Important Project technical need.
Sulfate in municipal wastewater（SO4 2-）Concentration is generally in 20-200 mg/L, and some enterprises produce waste water node SO can then be dramatically increased by being discharged into pipe network4 2-Concentration.In municipal wastewater pipeline bottom anaerobic zone, SO4 2-First in bed mud sulfate also Opportunistic pathogen（SRB）Sulfide is converted under effect（S2-）, S2-Again with the hydrogen ion in water（H+）With reference to generation H2S is escaped.It is municipal dirty Waterpipe is difficult to set H2S centralized collection processing units, therefore, from H2S in root caused by S, i.e. sewage2-Produce and be transformed into Hand solves H2S releases problem has stronger realistic meaning.Conventional method is by adding bactericide into pipeline（As follows chlorine Sour sodium, molybdate etc.）, highly basic, metal ion etc., inactivated by SRB, improve pH, precipitation S2-Suppress etc. mode or eliminate S2-, Advantage is that effect is rapid, and shortcoming is that cost is higher and constitute unfavorable factor to follow-up sewage plant biochemical treatment.Bioanalysis converts S2-Technology then relative clean, mainly utilizes nitrate nitrogen（NO3 -）, oxygen（O2）Deng electron acceptor by S2-It is converted into other morphologizations Close sulphur（S0, SO4 2-, S2O3 2-Deng）, and bioanalysis is in S2-Convert and taken advantage in the controllability of target product, while cost is relative It is relatively low, it has also become the focus and emphasis of research and technology application.
Some crucial emission point positions or sewage in sewage conduct stockpile place, such as resident compact district floss hole, chemical industry The pipeline junctions such as plant effluent mouth, emphasis pumping plant, S caused by usual duct bottom2-Concentration is higher, H2S releases are stronger.NO3 -Deng Electron acceptor is together flowed with sewage in the duct, and advantage is, " face source " property can be played to the sewage conduct of certain length S2-Control action.At present, it is directed to and produces S2-The higher sewage conduct node of concentration, then lack " point source " of strong applicability Property sulphur transformation technology.
Microorganism electrochemical technology/system（Bio-electrochemical System, Bes）, it is Conventional electrochemical system The redox reaction that anode and the negative electrode at least side of system are carried out under microorganism catalysis effect, it combines microorganism and electricity The advantage of chemistry, electrode can be as " fixation " electron acceptors of microorganism, and electron acceptor need not be additionally provided by having, and reaction is held The advantages such as the continuous strong, non-secondary pollution of property.Taken in research fields such as wastewater treatment, underground water, bed mud, soil remediation, energy recoveries It must develop rapidly, to solve sewage conduct " point source " property S2-Control provides breach.
The content of the invention
It is difficult to produce S to municipal sewage pipe network for existing " flowing " electron acceptor that adds2-The higher sewage well point of concentration Position carries out the problem of intensive control, it is an object of the invention to provide a kind of in situ regulation and control municipal wastewater pipeline sulphur conversion system and Its operation method, the system architecture is simple, sulphur changing effect is good, environmentally safe.
