Abstract
The invention provides a method for eliminating odor emitting by the water and bottom sludge in a river. The method is characterized in that: ferric oxide and sodium humate complex preparation is added into river water with the dosage of 10-30g per cubic meter. The weight percentage ratio of the ferric oxide and the sodium humate complex preparation is 50-70 percent of ferric oxide and 30-50 percent of sodium humate. The method of the invention can obviously inhibit water and bottom sludge in a river emitting odor, so as to avoid disturbing people.
Description
Technical field
The present invention relates to a kind of method that the volatility repugnant substance discharges in the river water body that suppresses.
Background technology
Owing to influenced by sanitary sewage and pollution of area source, the smelly phenomenon that disturbs residents of city river blackout is general.There are some researches show that hydrogen sulfide, volatility organic compounds containing sulfur are to cause the malodorous essential substance in river course.Under the anoxia condition in water and the bed mud decomposition of sulfurous organic compound and sulfate reduction be the main generation approach of hydrogen sulfide, volatility sulfurous organic compound (thiomethyl alcohol, dimethyl sulfide, dimethyl disulfide etc.).The basic solution route of river course stench problem is to come the river training water surrounding by a section dirt, desilting, additional ecological water.Take under the situation of engineering measure being difficult to extensive enforcement, the method for taking to add on the spot medicament alleviates the water body stench and discharges and still have practical significance.Be used at present eliminating or alleviating the malodorous on-the-spot disposal method of water body mainly containing microbial process, and add the method that nitrate improves redox potential.Microbial process by adding effective microorganism preparation, is accelerated the oxygenolysis of malodorant, but need be combined with the oxygenation means exactly, generally is difficult at the shallow place of water realize, trouble is gone up in operation in addition, and cost is also than higher.The method that adds nitrate is to suppressing sulfate reduction, alleviate sulfurous gas and discharge and have obvious effect, and its shortcoming is to be difficult for adding in the river bottom mud, easily runs off, and easily causes secondary pollution.
Summary of the invention
Deficiency in view of existing related art method the objective of the invention is: proposes a kind of to suppressing and alleviate that the release of volatility malodorant has positive effect in river water body and the bed mud, and easy and simple to handle, lower-cost method.
The present invention is achieved by the following technical solutions: preparation ferric oxide and humic acid are received compound formulation, compound formulation proportioning following (weight percent): ferric oxide 50-70%, humic acid receive 30-50%.Add ferric oxide and sodium humate compound formulation in black and odorous water, each dosage is every cubic metre of water body 10～30 grams.Earlier with 10-20 times of water furnishing suspension liquid, in smelly water body, evenly spill when adding.Utilization the inventive method can obviously suppress the release of volatility malodorant in water and the bed mud, alleviates the degree of disturbing residents.
Useful technique effect of the present invention is as follows:
(1) the inventive method, by in water body, adding ferric oxide and sodium humate compound formulation, improve the water body iron level, build the iron reducing environment, thereby supression sulfate reduction, reduce sulfide content in the water, restrain the release of hydrogen sulfide and volatility sulfurous organic compound, alleviate the stench degree.Ferric iron is behind reduction formation ferrous iron in addition, and free divalent sulfur also is the approach that reduces hydrogen sulfide and the release of volatility sulfurous organic compound in conjunction with forming the iron sulphide precipitation among the Yi Yushui.
(2) find in the experimental study that ferric oxide and sodium humate are composite, compare, can obviously improve the inhibition degree that water body volatility sulfur-containing foul compound is discharged with adding ferric oxide separately.Aspect the release of inhibition volatility sulfur-containing foul compound, ferric oxide and sodium humate have obvious synergistic promoter action [experimental data is referring to embodiment 1 in detail].The effect of sodium humate mainly be promote ferric oxide dissolving, form iron complex, promote the growth of iron reducing bacteria, and then restrain the release of hydrogen sulfide and volatility sulfurous organic compound.
(3) ferric oxide that the present invention relates to and sodium humate compound formulation, easily sinking under water plays a role, and is difficult for running off.
(4) the water body stench inhibition method that the present invention relates to can less, the toxicological harmless of used chemical usage quantity, the stench that can be used for alleviating municipal pollution river course, sewage ditch, pond, the little lake problem that disturbs residents.
Below being ferric oxide of the present invention and sodium humate compound formulation is suppressing aspect the release of volatility sulfur-containing foul compound the test examples and the result of the collaborative promoter action of ferric oxide and sodium humate:
Sewage lagoon at four 0.8 meter * 1.5 meters compares test.Four pond initial condition are basic identical.Thick about 15 centimetres of bed mud, dark about 70 centimetres of overlying water.Sewage and bed mud are taken from serious pollution river, a place and are gushed.One of them is pond (numbering contrast pond 0#) in contrast, and the contrast pond is adding medicine not.Other three as experiment pool.All there is the measure of the rain of screening in four ponds, and duration of test does not change water.Duration of test temperature is 21～30 ℃.
In three experiment pool, (proportioning is a ferric oxide 50% to add 20 gram ferric oxide and sodium humate compound formulation when one of them pond (numbering experiment pool 1#) test is initial in water, sodium humate 50%), with evenly spilling behind the 400 gram water furnishing suspension liquids, in experiment pool, added 20 gram ferric oxide and sodium humate compound formulations later on every 30 days, test when initial and test the 30th day, the 60th day, the concentration (hydrogen sulfide of typical volatility repugnant substance in the air sample on the difference determination experiment pond and the contrast pond water surface, thiomethyl alcohol, dimethyl sulfide, dimethyl disulfide).
Other two ponds in three experiment pool are tested and add single compositions of 20 gram ferric oxide (numbering experiment pool 2#) and the single composition of sodium humate (numbering experiment pool 3#) when initial respectively in water.Add dosage, frequency, and the sampling analysis method is the same.
Following table is for contrasting volatility repugnant substance concentration changes with time situation (concentration unit: mg/m on pond 0# and experiment pool 1#, 2#, the 3# water surface
3).
