Abstract
The invention discloses a processing method of bean skim wastewater. The method includes the following steps of a, mixing and stirring alkaline matter, polyacrylamide and water so that alkaline matter and polyacrylamide can be sufficiently dissolved and mixed; b, adding the mixed materials to the bean skim wastewater so that suspended matter in the bean skim wastewater can be flocculated. By means of the method, by mixing alkaline matter and polyacrylamide for use, the pH value of the solution can be increased, the attraction of polyacrylamide and suspended solid particles with positive charges in the bean skim wastewater can be easily promoted, flocculation is promoted, the airflow flocculation effect is improved, and suspended matter removal rate is increased.
Description
Technical field
The present invention relates to air supporting flocculation treatment technology, more precisely, the present invention relates to a kind of Semen sojae atricolor and divide
The processing method of waste water in protein manufacturing process.
Background technology
Containing substantial amounts of float in the waste water produced during producing albumen, suspend containing a large amount of
The waste water of thing can have a strong impact on anaerobism and run after entering anaerobic system, makes seriously to run in anaerobism running
Mud, causes granule sludge to run off, and anaerobism can be caused time serious to paralyse, so before waste water enters anaerobism
The process of float must be removed, the general float used in air-float method removal waste water, often
Rule air supporting method uses aluminium polychlorid and two kinds of flocculant of polyacrylamide, because amide flocculating effect has
Limit, the removal efficiency of the method typically only 75%, removal efficiency is low, can't be complete
Meet the condition requirement of anaerobism water inlet, and aluminium polychlorid and polyacrylamide amount ratio are relatively big, make
Become cost higher.
Summary of the invention
The present invention is to solve problems of the prior art, it is provided that the process side of a kind of bean stripping water
Method.
The technical scheme is that the processing method of a kind of bean stripping water, comprise the following steps:
A) being mixed with polyacrylamide, water by alkaline matter, stirring makes alkaline matter, polypropylene
Amide fully dissolves, mixes；
B) above-mentioned mixed material is added to bean stripping water, make the float in bean stripping water flocculate.
Preferably, described alkaline matter is sodium hydroxide.
Preferably, the addition of described alkaline matter is that polyacrylamide adds the 5% of quality.
Preferably, in described step a), after mixing, the concentration of solution is 1.5 ‰.
The processing method of the bean stripping water that the present invention provides, mixes alkaline matter with polyacrylamide
Use, such that it is able to improve the pH value of solution, thus may advantageously facilitate in polyacrylamide and bean stripping water
Suspended solids with positive charge attracts each other, thus promotes the carrying out of flocculation, improves air supporting flocculation effect
Really, removal efficiency is improved.
Detailed description of the invention
Below by embodiment, the present invention will be further described, but these embodiments are not limiting as the present invention's
Protection domain.
The invention provides the processing method of a kind of bean stripping water, it comprises the steps:
Step 1: add clear water in dissolving tank to just flooding stirring wing；
Step 2: adding alkaline matter in dissolving tank, specifically, this alkaline matter can be sodium hydroxide,
Or other alkaline matter well-known to those skilled in the art, the addition of alkaline matter is preferably polypropylene
The 5% of amide quality, and stir 2 minutes so that it is it is sufficiently mixed dissolving after mixing；
Step 3: adding polyacrylamide in tank, fill it up with clear water simultaneously, the concentration of the final solution made is
1.5 ‰, can use after stirring 60 minutes.
Step 4: the polyacrylamide (containing alkaline matter A) dissolved is added in bean stripping water, bean
The float floccule body of stripping water increases so that removal efficiency improves 5%.
The processing method of the bean stripping water that the present invention provides, mixes alkaline matter with polyacrylamide
Use, such that it is able to improve the pH value of solution, thus may advantageously facilitate in polyacrylamide and bean stripping water
Suspended solids with positive charge attracts each other, thus promotes the carrying out of flocculation, improves air supporting flocculation effect
Really, removal efficiency is improved.
By this engineer testing, ton waste water alkaline matter often increases 0.2kg, and the consumption of polyacrylamide reduces
0.05Kg, totle drilling cost saving 0.25 yuan, removal efficiency improves 5% simultaneously.In the present invention above-mentioned
Each parameter can select according to being actually needed of those skilled in the art.
Above-described embodiment is only example character.For those skilled in the art, it is possible to understand that without departing from
These embodiments can be carried out in the case of the principle of the present invention and spirit multiple change, revise, replace and
Degeneration, the scope of the present invention claims again and equivalent thereof limit.
Claims (4)
