Description
Technical field
The present invention relates to field of environment pollution control more particularly to it is a kind of for black and odorous water in-situ sediment remediation administer
Solid union biological agent and preparation method thereof.
Background technology
With China's sustained economic development, industrialized level is continuously improved, and urbanization rapidly promotes and living standards of the people
Constantly improve, the yield of sanitary sewage and trade effluent increases year by year, since the shortcoming and water pollution of people's environmental consciousness are controlled
The lag of facility is managed, a large amount of sewage is directly discharged into urban water-body, causes the black smelly phenomenon of Urban Water Ecological Environment.
The most immediate cause that water body generates black smelly phenomenon is exactly that organic pollution is excessive, and oxygen demand is big when microorganism decomposition,
Oxygen consumption in water body is set to be more than reoxygenation, content of oxygen dissolved in water is less than 2mg/L, eventually leads to water body self-purification ability and disintegrate comprehensively.
Urban water-body is black smelly mainly to be caused by following reason：
One, exogenous pollution object is divided into point-source pollution and pollution of area source.Wherein point-source pollution has the in line mouth of stain disease, conjunction
Stream overflow port, pipe network initial rainwater and unconventional water source moisturizing, pollution of area source have urban precipitation runoff, ice dissolution and livestock and poultry
Breeding wastewater.
Two, endogenous sediments re-suspension.Pollutant and ammonia nitrogen in bed mud go out under acid, reducing condition from sediment release
Come, the gases such as H2S, CH4 of generation bring the pollutant being adsorbed in sediment particles into water phase in uphill process, a large amount of to suspend
Object floats in water, leads to water body blackening.In addition, bed mud provides good growing environment for microorganism, wherein cyanobacteria and put
Line bacterium promotes bed mud methanation, denitrification by metabolism, causes bed mud floating and black and odorous water.
Black and odorous water is eliminated thus, in addition to control external source pollution, also needs to carry out improvement reparation to bed mud, currently, bed mud is controlled
Reason recovery technique mainly has a showering and in-situ immobilization, and wherein showering technology refers mainly to dredging for dredging technology and bed mud
Post-processing technology is dredged, bed mud Ex-situ remediation method is of high cost since quantities is big, and dredging depth is difficult to control, at follow-up sludge
It manages the big problem of difficulty and receives limitation.In-situ immobilization mainly include curing/stabilizing, the methods of chemical remediation, biological prosthetic,
The problems such as curing/stabilizing and chemical remediation discharge again there are reagent cost height, pollutant, it is biological prosthetic thus to obtain extensively
Favor, but at present there is the problems such as being easy to run off, dosage is big, efficiency is low, of high cost in bed mud bioremediation agents, thus, it would be highly desirable to develop
A kind of sediment in-situ bioremediation agents that treatment effeciency is high, adaptable, cheap.
