Abstract

The present invention discloses a kind of Sludge deodorant, belongs to technical field of sludge treatment, is made up of the raw material of following percentage by weight：Bentonite 25 ~ 35%, ferrous sulfate 15 ~ 30%, calcium oxide powder 5 ~ 8%, magnesia powder 1 ~ 3%, hypochlorous acid calcium powder 10 ~ 20%, cane powder 15 ~ 20%, porous powder of straw 1 ~ 10%.The present invention by the use of bentonite, ferrous sulfate, calcium oxide powder, magnesia powder, hypochlorous acid calcium powder, cane powder, porous powder of straw as Sludge deodorant raw material, when being applied to sludge deodorization, by physical absorption and chemical reaction double action, the effectively quick foul gas removed in sludge, and raw material sources are abundant, cheap, economic and environment-friendly, it is adding less and preparation method is simple.

Description

A kind of Sludge deodorant
Technical field
The invention belongs to technical field of sludge treatment, and in particular to a kind of Sludge deodorant.
Background technology
Sludge be sewage through the product after treatment, the product yield is big, moisture percentage in sewage sludge is high, there is stacking floor space Greatly, cost of transportation is high, the intractable problem of percolate, is also easy to produce stench and grows mosquitos and flies, causes serious environmental problem, then Person, sludge concentration, mechanical dehydration, transport, storage, can also discharge a large amount of effluviums during the treatment such as compost and landfill Body.Therefore, the malodor problem that sludge causes turns into the bottleneck in Treatment of Sludge resource.
At present, the method for suppressing the release of sludge foul gas mainly has physical deodorization method, chemical deodorizing method, biological deodorizing Method.Physical deodorization method is mainly to sorbing material, such as activated carbon is added in sludge, to suppress the release of sludge foul gas but dirty The production cost of mud deodorant is high, and deodorizing effect is not good.Chemical deodorizing method is to adding chemical reagent, such as O in sludge3、 H2O2, NaClO etc., with the activity, the oxidation that reach the oxidation-reduction potential improved in sludge, reduce sulfate reducing bacteria in sludge The effect of the release of foul gas in the foul gas such as hydrogen sulfide, reduction sludge, but traditional chemical reagent, exist and are difficult to improve Oxidation-reduction potential, the problem that the deodorization time is short, additive amount of medicament is larger in sludge system.Biological odor removal method is to dirt Microorganism, such as CEM (EM bacterium) are added in mud, to reach using the degradation of microorganism, odorant is decomposed Innocuous substance is changed into, so that the effect of the release of foul gas in sludge is reduced, but breeding strain and preservation are difficult, and in the presence of at Manage the problem of the effect on driving birds is not good of stench.
Therefore, develop that a kind of economic and environment-friendly, preparation method is simple and Sludge deodorant of good deodorization effect, it has also become dirty The difficult point and focus of mud processing technology field.
The content of the invention
Present invention aim at a kind of compound type sludge deodorant of good deodorization effect of offer.
Based on above-mentioned purpose, the present invention takes following technical scheme：
A kind of Sludge deodorant, is made up of the raw material of following percentage by weight：Bentonite 25 ~ 35%, ferrous sulfate 15 ~ 30%, oxygen Change calcium powder 5 ~ 8%, magnesia powder 1 ~ 3%, hypochlorous acid calcium powder 10 ~ 20%, cane powder 15 ~ 20%, porous powder of straw 1 ~ 10%.
The porous powder of straw is selected from the mixed of one or more in sunflower pole powder, milled powders of cornstalk, kaoliang stalk powder Compound.
The calcium oxide powder, hypochlorous acid calcium powder, cane powder, the mesh number of porous powder of straw are 200 ~ 500 mesh.
The mesh number of the magnesia powder is 200 mesh.
The preparation method of Sludge deodorant of the present invention：Can be well mixed by siccative mixer by each raw material.
Application method during sludge deodorization：The addition 5% ~ 10% of Sludge deodorant of the invention, addition is removed for sludge The ratio between smelly dose and sludge quality, above-mentioned Sludge deodorant is divided into input sludge twice, and every time after input, stirring mixes it Uniformly, then stood under normal temperature.
Compared with prior art, the invention has the advantages that：
The present invention is using bentonite, ferrous sulfate, calcium oxide powder, magnesia powder, hypochlorous acid calcium powder, cane powder, porous powder of straw Used as the raw material of Sludge deodorant, raw material is cheap and easy to get, environmental protection, anti-by physical absorption and chemistry when being applied to sludge deodorization Double action is answered, the effectively quick foul gas removed in sludge, and raw material sources are abundant, cheap, economic and environment-friendly, and system Preparation Method is simple, adding less.
