Description
Technical field
The invention belongs to water environment pollution control techniques field, be specifically related to a kind of black smelly compound and preparation and method of use of water body that suppress.
Background technology
A large amount of trade effluents, the unprocessed water body that just enters of sewage have caused water quality deterioration, and dissolved oxygen concentration reduces, even approach exhaustion.Under anaerobic; Organism in water body and the bed mud can be produced black deposits such as Iron sulfuret in the process of anaerobic digestion; Produce foul gass such as hydrogen sulfide, ammonia simultaneously; Black deposit can cause water body black smelly under the supporting of foul gas is stirred when serious, the self function is lost basically.In China, southern area especially, the black smelly phenomenon of water body is comparatively general.How suppressing black smelly, the recovery self function of water body effectively, is one of content that needs to be resolved hurrily in the water environment pollution control.
The black smelly technology of inhibition water body commonly used comprises bed mud dredging, biological prosthetic, artificial aeration etc.The bed mud dredging is controlled through the polluted bed mud of excavating the top layer and is reduced black smelly source, but bed mud dredging technology quantities is big, and cost is high, can cause certain destruction to water ecosystem, and the engineering Failure cases also has appears in the newspapers.Mikrobe preparation for repairing cost is high, and the quality guaranteed period is short, and effect slowly also receives the water surrounding condition restriction, is difficult to use on a large scale; The phytoremediation growth cycle is long, needs regularly harvesting, and actual effect is not obvious.The artificial aeration can increase oxygen in water content fast, and water body is black smellyly to have better effects to suppressing, but this technical costs is higher, and oxygen transfer efficiency is lower, also possibly cause on the bed mud when using in the shoaling water and turn over, and discharges certain pollutent.Therefore, development and operation convenient, with low cost, use widely the black smelly inhibition technology of water body to have the important engineering meaning.
Summary of the invention
The object of the invention is to overcome the prior art deficiency, and a kind of dissolved oxygen, the black smelly compound of inhibition water body and preparation method thereof and method of use of increasing is provided.
Inhibition water body provided by the present invention is deceived smelly compound, is that the zeolite powder of 70%-90% and the A material of 10%-30% are formed by the quality percentage composition; Wherein, said A material be selected from following any one: calcium superoxide, sodium carbonate peroxide and nitrocalcite.
Said compound exists with the particulate form, and said particle grain size is preferably 3-10mm.
The preparation method of compound provided by the present invention comprises the steps: zeolite powder and the said A material ratio mixing according to mass ratio 70-90: 10-30, processes the particle that particle diameter is 3-10mm through mechanical-moulded, promptly obtains said compound; Wherein, said A material be selected from following any one: calcium superoxide, sodium carbonate peroxide, nitrocalcite.
The method of use of compound provided by the present invention is that said compound is evenly thrown to the lake water environment of river, and dosage is 0.5-2kg/m
