Abstract
The invention relates to the technical field of water treatment chemicals, in particular to papermaking sewage treatment flocculant and a preparation method thereof. The papermaking sewage treatment flocculant is made of, by weight, 20-30 parts of polyacrylamide, 3-8 parts of chitosan, 5-15 parts of polymeric ferric sulfate and 100-120 parts of distilled water. The papermaking sewage treatment flocculant is effective on papermaking sewage flocculated sedimentation, quick in treatment and easy in sedimentation.
Description
Technical field
The present invention relates to the water treatment agent technical field, especially a kind of papermaking wastewater flocculant for treating and method of manufacture thereof.
Background technology
At present, paper industry is one of the world's six big industrial pollution sources, and the wastewater flow rate that it produces accounts for 10% of the total wastewater flow rate of domestic industry.Paper waste produces link by it and is divided into pulping waste liquor, middle section water and paper machine white water.Pulping waste liquor can obtain recycling through the alkali recovery process of routine; But direct reuse was in production after paper machine white water was handled through air supporting or polydisc vacuum filtration etc.; Usually said paper waste mainly refers to middle section water; It contains lignin, semicellulose, carbohydrate, residual alkali, inorganic salt, volatile acid, organic chloride etc.; Have that quantity discharged is big, COD is high, Ph vary within wide limits, colourity are high, characteristics such as thio-alcohol foul odour, biodegradability difference are arranged, and belong to more unmanageable trade effluent.For effectively controlling the water environment degradation and alleviation water resources situation in short supply day by day that paper industry brings; Countries in the world continue to increase the environmental law enforcement dynamics to paper industry; Both required waste discharge water quality reaching standard, total emissions of major pollutants up to standard, again ton product fresh water consumption had been controlled.
Summary of the invention
The object of the present invention is to provide a kind of papermaking wastewater flocculant for treating and method of manufacture thereof, mainly solve above-mentioned existing in prior technology technical problem, it is to have good effect to the papermaking wastewater flocculation sediment, the fast deposition easily of its processing speed.
For realizing above-mentioned purpose, the present invention realizes like this.
A kind of papermaking wastewater flocculant for treating is characterized in that: it is 20～30 parts of SEPIGEL 305s according to the composition of parts by weight, 3～8 parts of chitosans, 5～15 parts of bodied ferric sulfates, 100～120 parts of zero(ppm) water.
A kind of method of manufacture of aforesaid papermaking wastewater flocculant for treating is characterized in that: earlier zero(ppm) water is added in the reaction vessel, then successively with SEPIGEL 305; Chitosan, bodied ferric sulfate adds in the reaction vessel, stirs; Fully dissolving gets product.
The advantage that prescription of the present invention and method can embody is:
1, employed chitosan in the disclosed a kind of papermaking wastewater flocculant for treating of the present invention, it has the porous globule, and heavy metal is had sequestering action, and the suspended substance in the sewage is flocculated rapidly, natural sedimentation, the yield of raising stoste.
2, employed bodied ferric sulfate in the disclosed a kind of papermaking wastewater flocculant for treating of the present invention, it is good that it has coagulation performance, and alumen ustum is closely knit, and settling velocity is fast; And to papermaking wastewater have turbidity removal, decolouring, de-oiling, dehydration, degerming, deodorizing, remove algae, to remove in the water effects such as COD, BOD and heavy metal ion remarkable.
3, the disclosed a kind of papermaking wastewater flocculant for treating of the present invention is in use nontoxic, safe and reliable, and low than other products of the same type to the corrosion of system device.
Embodiment
Embodiment 1: earlier 100 parts of zero(ppm) water added in the reaction vessel, and then successively with 20 parts of SEPIGEL 305s, 3 parts of chitosans, 5 parts of bodied ferric sulfates add in the reaction vessel, stir, and fully dissolving gets product.
Embodiment 2: earlier 115 parts of zero(ppm) water added in the reaction vessel, and then successively with 25 parts of SEPIGEL 305s, 5 parts of chitosans, 10 parts of bodied ferric sulfates add in the reaction vessel, stir, and fully dissolving gets product.
Embodiment 3: earlier 120 parts of zero(ppm) water added in the reaction vessel, and then successively with 30 parts of SEPIGEL 305s, 8 parts of chitosans, 15 parts of bodied ferric sulfates add in the reaction vessel, stir, and fully dissolving gets product.
Being merely preferred embodiment of the present invention in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should be technological category of the present invention.
Claims (2)
1. papermaking wastewater flocculant for treating, it is characterized in that: it is 20～30 parts of SEPIGEL 305s according to the composition of parts by weight, 3～8 parts of chitosans, 5～15 parts of bodied ferric sulfates, 100～120 parts of zero(ppm) water.
2. the method for manufacture of a papermaking wastewater flocculant for treating as claimed in claim 1 is characterized in that: earlier zero(ppm) water is added in the reaction vessel, then successively with SEPIGEL 305; Chitosan, bodied ferric sulfate adds in the reaction vessel, stirs; Fully dissolving gets product.
