Description
Technical field
The present invention relates to the method that a kind of activity that strengthens sulphate reducing bacteria improves waste water treatment efficiency.Belong to and utilize sulphate reducing bacteria to handle waste water technology.
Background technology
Acid waste water is modal a kind of in the trade effluent, and it is mainly from mine (draining), plating, electrolysis, dyestuff and pharmaceutical industry etc.Its principal character shows as: low pH value, contain high density vitriol, contain the heavy metal ion of solubility.The acid waste water that contains heavy metal is very harmful to environment, industrial and agricultural production and human beings'health, must handle.Handle this type of waste water at present and mainly use lime neutralisation and wetland method, the lime neutralisation can produce a large amount of solid waste (gypsum and heavy metal hydroxide) in treating processes, need secondary treatment, otherwise will cause secondary pollution, so increased difficulty and the cost handled.Wetland method floor space is big, is restricted in actual applications.
Utilize the physiological property of nature sulphur cycle principle and sulphate reducing bacteria, handling acid heavy metal waste water with microbial method is a kind of emerging technology.Sulphate reducing bacteria is one group of general designation of carrying out the relevant bacterium of sulfate reduction metabolic reaction, at present, existing 12 of the bacterial classification of the sulphate reducing bacteria that research obtains belongs to nearly more than 40 kinds, comprising Desulfovibrio, Desulfomonas, Desulfotomaculum, Desulfococcus, Desulfobacter, Desulfonema etc., what be used for wastewater treatment mainly contains Desulfovibrio, Desulfomonas and Desulfotomculum.So their unique distinction is in unique microorganism that can carry out anaerobic respiration with sulfate radical as final electron acceptor(EA).This bacterium utilizes organism as electron donor, by under anaerobic the required energy of existence being obtained in organic degraded, simultaneously sulfate radical is reduced to sulfonium ion and elemental sulfur.In this course, the pH value of waste water obtains improving, and sulfate concentration descends, and the sulfonium ion of heavy metal ion and generation forms the metallic sulfide precipitation and removed, and waste water quality improves.This technology is compared with existing treatment process to have and is removed heavy metal ion efficient height, generates that sludge quantity is few, precipitation is difficult for the secondary dissolving and characteristics such as adaptability is strong, has higher using value in practice.But the metabolic activity of sulphate reducing bacteria is subjected to the limitations affect of multiple factor, as organic carbon source concentration, sulfate concentration, temperature, waste water ph and heavy metal ion kind and concentration etc., so in the actual waste water treating processes, may cause it actively to reduce even be suppressed owing to the growth that waste water condition (low pH value, contain heavy metal ion) or operational condition (normal temperature is operation down) are not suitable for bacterium, thereby make the waste water treatment efficiency reduction.
Summary of the invention
The object of the present invention is to provide a kind of activity that strengthens sulphate reducing bacteria to improve the method for waste water treatment efficiency.This method has strengthened the activity of sulphate reducing bacteria effectively, has improved the processing efficiency of waste water, and process is simple, applied range.
For achieving the above object, the present invention is realized by following technical proposals.Adopt upflow type anaerobic multiple-hearth bio-reactor, utilize the sulphate reducing bacteria mixed strains, handle and contain Cr

2+Acid waste water process etc. heavy metal ion, strengthen the activity of sulphate reducing bacteria, improve the method for waste water treatment efficiency, it is characterized in that, in reactor or in the wastewater trough (jar), add fe, add-on causes the pH value of sewage to reach 5.5～8.5, and carries out biochemical reaction at 25～30 ℃.
Above-mentioned fe is iron powder, iron filings, iron sand.
The invention has the advantages that, in the system of utilizing sulphate reducing bacteria processing acid heavy metal waste water, by adding fe, can improve the pH value of waste water, improve the living environment of bacterium, nutraceutical matrixes such as iron ion and hydrogen are provided for bacterium simultaneously, thereby can make bacterium can keep good metabolic activity, shorten the cell cessation of growth cessation phase, strengthen sulphate reducing bacteria sulfate radical is reduced to the ability of sulfonium ion, improve bacterial adaptation and waste water treatment efficiency.
Embodiment
The present invention has carried out utilizing fe to strengthen the research of sulfate reducing bacteria activity, and its conclusion can be widely used in utilizing the various field of waste water treatment of sulphate reducing bacteria method, as same for treating acidic mine wastewater, electroplating wastewater, leather-making waste water etc.When using this technology, conditions such as treatment capacity that reaches according to composition, character, pH value and the requirement of treatment sewage and treatment effect are earlier determined the add-on of fe; Load carrier filler then, seed sludge; After treating microorganism colonization, earlier iron powder is added in the reactor, with peristaltic pump sewage is sent into reactor again and handle.In continuous treating processes, should regularly add iron powder according to wastewater treatment capacity, to keep the activity of sulphate reducing bacteria.
This research is adopted is mixed sulfate reduction bacterium bacterial classification based on Desulfovibrio (desulfovibrio), and processing is by Cr
