Abstract
The invention provides a sludge deodorant and a deodorizing method. The sludge deodorant comprises the following components by mass percent: 5wt%-20wt% of ethyl orthosilicate, 5wt%-20wt% of vinylidene fluoride, 1wt%-5wt% of polyethylene glycol, 10wt%-50wt% of methyl alcohol, and the balance of water. The sludge deodorant rapidly forms an isolating membrane on the surface of stacked sludge so as to close and isolate the sludge, so that odor of the sludge is prevented from leaking, and air is prevented from entering the sludge to cause the sludge to ferment, therefore, the sludge deodorant realizes the effects of isolating and deodorizing.
Description
Technical field
The present invention relates to a kind of Sludge deodorant and deodorizing method, belong to mud purification techniques field.
Background technology
Mud is in process disposal process, and can discharge foul gas, be the important source of pollution causing foul smell to discharge, and therefore must effectively control odor pollution problem in the whole transport and processing links of mud.
Mainly contain two class methods to the deodorizing of mud in prior art, a class is enhanced leaktightness and carries out foul smell extraction to focus on; Another kind of is spray sequestering agent to hide its stink.But in many occasions such as mud stockyard, site area is large, and open environment, is difficult to carry out sealing to whole region and bleeds, and amount of overflowing because foul smell is loose is large, and the effect of spraying sequestering agent is not good yet, therefore easily becomes discharge point environment being had to larger pollution.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is to propose a kind of Sludge deodorant and deodorizing method, isolation mud can be closed, realize sludge deodorization.
Object of the present invention is achieved by the following technical programs:
A kind of Sludge deodorant, by percentage to the quality, comprises following moiety:
Tetraethoxy 5wt%-20wt%, vinylidene 5wt%-20wt%, polyoxyethylene glycol 1wt%-5wt%, methyl alcohol 10wt%-50wt%, its surplus is water.
The present invention also provides the preparation method of above-mentioned Sludge deodorant, comprises the steps:
By soluble in water to tetraethoxy, vinylidene, polyoxyethylene glycol and methyl alcohol, regulate pH value to be 3-4 with acid, obtain Sludge deodorant.
The present invention also provides a kind of method using above-mentioned Sludge deodorant to carry out sludge deodorization, comprises the following steps:
Processed is carried out to mud, makes the water ratio of mud be less than or equal to 80%, dehydration, mummification etc. can be adopted to realize;
By soluble in water to tetraethoxy, vinylidene, polyoxyethylene glycol and methyl alcohol, regulate pH value to be 3-4 with acid, obtain Sludge deodorant;
With sprinker, reodorant is sprayed onto sludge surface with form of foam, piles up depth of foam and reach more than 1 centimetre, leave standstill.
In above-mentioned method, the acid related to includes but not limited to hydrochloric acid.
Above-mentioned Sludge deodorant and deodorizing method comprise the functional materialss such as membrane-forming agent, dispersion agent, whipping agent, can guarantee that formed mould material has good isolation effect, be sprayed onto after on sludge surface and form the barrier film that one deck has obviously blocking-up gas channel, the foul smell in mud can not only be avoided like this to reveal, also can block air and enter mud generation fermentation.
Outstanding effect of the present invention is:
The present invention utilizes medicament to form barrier film fast in sludge surface, can close isolation mud, avoids the foul smell in mud to reveal, and can also block air and enter mud generation fermentation, realize the effect of isolation deodorizing.
Embodiment
Following constipation closes embodiment and is described in further detail, and is easier to understand, grasp to make technical solution of the present invention.
