Below, the result of soil sludge treatment is described.
200 milliliters (below, mL) in the draining of mimic soil mud, adopt the flocculation agent of flocculation agent of the present invention (A), flocculation agent (B), market sale, their effect of comparative studies.
Its result, the flocculation agent of market sale must 800mg, but flocculation agent of the present invention (A) drops into 200mg, flocculation agent of the present invention (B) drops into 300mg, and stirs, then generate flocculation sediment, the transmissivity of the clarifying aqueous solution is that flocculation agent of the present invention (A) obtains good transmission result.
Below, the result that the draining that contains starch is handled describes.
As the potency test of the flocculation agent of the present invention (A) of simulation process agent, trial-production contains the draining of 10g/L and 20g/L starch, adds 200mg and 300mg flocculation agent of the present invention (A) in 200mL respectively, observes the flocculation state.
Its result, the whichever condition all is considered to generate good flocculation sediment.
Therefore, as the ability test of flocculation agent of the present invention (A), try to achieve the addition with respect to the draining of 10g/L starch, minimum as can be known addition is 40mg.
Below, the result that the draining that contains washing water of rice is handled describes.
(1 closes=180.39mL) implements common rice washing method, has used 200mL with the blended draining of washing rice for the second time for the first time to close rice to 4.
As flocculation agent, add the flocculation agent of flocculation agent of the present invention (A) and market sale, and compare their effectiveness.
Its result, flocculation agent of the present invention (A) begins flocculation when adding 170mg to, finish flocculation in 250mg substantially.
Final flocculation needs 500mg.In addition, can observe the flocculation of floss, gather in top along with the process of time.
On the other hand, the flocculation agent of market sale is adding under the situation of 800mg, does not generate flocculation fully, and outstanding turbid state is white in color.
And then the result that the draining of noodle soup is handled describes.
In experiment, adopt the noodle soup of 20 of noodles in 3L hot water (more than 90 ℃), having dissolved market sale.Doubly dilute at 200mL8, in 4 times of dilutions and the solution of 2 times of dilutions, adopt flocculation agent of the present invention (A) as flocculation agent, the solution of 8 times of dilutions has added 135mg, and the solution of 4 times of dilutions has added 195mg, and the solution of 2 times of dilutions has added 350mg.Owing to make the starch flocculation,, and can observe the state of flocculation so the floss that generates forms floating state in solution.
And, adopting flocculation agent of the present invention (A) and flocculation agent (B), the pH value representation of the draining of having handled at the draining of having dissolved soil mud, cooking starch, milk respectively and washing water of rice etc. is in following table 1.
