Technical field
The present invention relates to the technical field of environment remediation, more particularly to a kind of in-situ immobilization black and odorous water bed mud medicament and
Preparation method and application.
Background technique
With the fast development of industrial or agricultural, more and more productions and sanitary wastewater excess emissions lead to river into river
Nutrient in flowing water body increases to be enriched with polluter, so that water quality deteriorates, generates black and odorous water.Black and odorous water is not
River crowd's living environment nearby is only influenced, and will lead to human health problems' appearance.Therefore, it is for black and odorous water improvement
The hot spot of aquatic ecological restoration.
Current black and odorous water recovery technique mainly includes external source Control Technology and endogenous Treatment process.With national policy and
The development of the relevant technologies, external source Control Technology repairing effect is significant, has prevented the discharge of xenobiotic pollutants substantially, therefore endogenous improvement
Technology is research hotspot instantly.According to the space-time boundary of recovery technique, endogenous Treatment process is divided into showering technology and original
Position recovery technique.It can destroy the aquatic environment of original water body relative to showering technology, rehabilitation cost height and be also easy to produce secondary
The problems such as pollution, based technique for in-situ remediation can effectively overcome problem above, and such as without a large amount of constructions, easy to operate, cost is relatively low,
It is smaller to the disturbance of original aquatic ecosystem, and be not easy to bring secondary pollution.Therefore, in-situ techniques are more paid close attention to.At present
Based technique for in-situ remediation mainly includes physical method, chemical method and three kinds of bioanalysis.Wherein physical method includes aeration oxygen replenishing, hidden covering
With riverbed landfill etc. technologies；Chemical method includes the technologies such as redox and passivation；Bioanalysis includes that phytoremediation and microorganism are repaired
Recovering technology.Because of bed mud diversity of organism and the complexity containing substance, using single physics, chemistry or biotechnology are all
It is difficult to repair black and odorous water, so how to be efficiently the weight of researcher's concern for the reparation of black and odorous water in conjunction with several technologies
Point.
