Abstract
The invention aims at providing a preparation method of a flocculating agent to reduce the cost of the flocculating agent. The preparation method comprises the following steps of A, crushing dried bentonite into 200 meshes of bentonite powder by a crusher; B, crushing zeolite into 200 meshes of zeolite powder; and C, crushing specific plant into 150 meshes of fiber, modifying the fiber by NaOH, then grafting by poly epsilon-caprolactone (PCL) to obtain the modified plant fiber, putting the bentonite powder, zeolite powder and modified plant fiber obtained in the steps into an external heating dual-shaft mixer according to the weight ratio of 4 to 4 to 2, heating the mixture in the stirring process, and finally packaging the mixture when the temperature achieves 50 DEG C to obtain a flocculating agent product, wherein the weight ratio of NaOH to the fiber is 1 to 100 and the weight ratio of poly epsilon-caprolactone to the fiber is 1 to 200.
Description
Technical field
The invention belongs to technical field of sewage, specially refer to a kind of preparation method of flocculation agent.
Background technology
Flocculation agent has strong adsorptivity, can make the fine-grained solids that disperses in liquid form the high molecular polymer of throw out, is must apply while disposing of sewage in the industries such as city domestic sewage, papermaking, metallurgy, chemical industry.Existing flocculation agent is to produce according to different raw materials and purposes, mainly contains polyacrylamide, polymerize aluminum chloride, and above-mentioned two kinds of flocculation agent costs are high, has brought heavy economic pressures to corresponding sewage disposal work.
Summary of the invention
The object of the invention is to propose a kind of preparation method of flocculation agent, to reduce the cost of flocculation agent.
The preparation method of flocculation agent of the present invention comprises the steps:
A: utilize pulverizer that dry bentonite in powder is broken to 200 object wilkinite powder;
B; Zeolite powder is broken to 200 object zeolite powders;
C: specified plant is crushed to 150 object fibers, and utilizes NaOH to carry out modification to described fiber, and then utilize poly-epsilon-caprolactone (PCL) to connect skill, obtain modified plant fibers; This is 1: 100 for the weight of described NaOH and fiber; This is 1: 200 for the weight of described poly-epsilon-caprolactone and fiber;
D: this example that the wilkinite powder that above-mentioned steps is obtained, zeolite powder, modified plant fibers are 4: 4: 2 according to weight ratio is put into external-heat double-shaft mixer and carried out mix and blend, in whipping process, mixture is heated, finally when mixture reaches 50 ℃, take out and pack, obtain flocculation agent finished product.
In aforementioned production method, in advance wilkinite and zeolite are pulverized, can make it fully mix with modified plant fibers, and reduce grinding cost.Raw material need not calcination and cleaning, and operation is simple, has reduced production cost.Product does not have strict high fineness and large this surface-area requirement, has both reduced production cost, has saved again facility investment; Adopt external-heat double-shaft mixer heat and mix, good uniformity, product performance are stable.
Further, described specified plant is one or more in rice husk, straw, sawdust, weeds, Pericarppium arachidis hypogaeae, tangerine bar.The plant waste that employing is easy to get is produced, and can further reduce costs.
Further, described wilkinite is calcium-base bentonite, to reduce costs.
Further, for guaranteeing to pulverize smoothly, in described B step, first utilize jaw crusher zeolite to be crushed to the particle of 0-20mm, and then utilize raymond mill by zeolite granular grinding to the 200 object zeolite powder obtaining.
The natural mineral that utilization of the present invention is easy to get and natural phant are as raw material, compound prescription is made flocculation agent, have advantages of that raw material sources are wide, cost is low, productivity is good, purposes is wide, can be widely used in the flocculation treatment of city domestic sewage, trade effluent, there is splendid application value.
