Abstract
The invention belongs to the technical field of environmental protection and relates to a light fiber coagulant aid prepared by agricultural wastes.The light fiber coagulant aid is prepared from, by mass, cotton stalk alcohol-alkaline filtrate 60-70%, guar gum 18-32%, an etherification agent 5-7% and a catalyst 3-5%.Due to the fact that the light fiber coagulant aid uses natural cotton stalks as a main synthetic raw material, the repeated utilization rate of agricultural wastes can be improved, effective components of the light fiber coagulant aid can be also fully utilized, and the synthetic coagulant aid is used for treating wastewater and is in compliance with the straw recycling and commercializing policies currently advocated by our country.
Description
Technical field
Patent of the present invention belongs to environmental technology field, is specifically related to the light fibre flocculation aid utilizing cotton stalk to prepare for raw material with guar gum.
Background technology
Cotton is the industrial crops that China is important, is the strategic materials involved the interests of the state and the people, relatively wide in China's cultivated area, and cotton stalk about 3375～3750kg is produced in per hectare cotton field.Cotton stalk, as agricultural residue, is mostly used as fuel and burns, or be deposited in ground, field.In the course of time go bad and become unserviceable waste material, cause huge waste.
Cotton stalk is rich in cellulose, lignin and pentosan.Knowable to cotton stalk composition, it is the desirable material of synthesis light fibre flocculation aid.At present, cotton stalk is used for the fields such as weaving, papermaking, prepares flocculation aid with cotton stalk for raw material and have not been reported, and therefore, the flocculation aid preparing coagulating is the new way of cotton stalk recycling.
Carrying out the research of synthesis flocculation aid comprehensive utilization for cotton stalk, it is thus achieved that high added value product, it is economical, social, environmental benefit is the most considerable.
Summary of the invention
For solving the problem of complex utilization of cotton stalk, the invention provides a kind of with cotton stalk and the guar gum light fibre flocculation aid as Material synthesis.
The present invention utilizes cotton stalk to prepare light fibre flocculation aid with guar gum.First cotton stalk after grinding heats in the alcohol alkali mixed solution that glycerine and potassium hydroxide are made clears up certain time, takes supernatant liquid and filters standby；Then catalyst, etherifying agent, guar gum are injected in hydrothermal synthesis reaction still with upper strata filtrate and add thermal response certain time, be cooled to room temperature, filtering reacting liquid body concentrating and precipitating, dry sediment and i.e. prepare light fibre flocculation aid.Light fibre flocculation aid is cotton stalk alcohol alkali filtrate 60-70%, guar gum 18-32%, etherifying agent 5-7%, catalyst 3-5% by each Ingredient percent.
Utilize cotton stalk to prepare light fibre flocculation aid with guar gum, be possible not only to improve the recycling rate of waterused of farmland discarded object, and waste water treatment can be carried out while effectively utilizing waste resource, meet the policy of current national energy-saving and emission-reduction, the treatment of wastes with processes of wastes against one another.
Detailed description of the invention
Embodiment one:
Learn from else's experience the cotton stalk after grinding, be heated in the alcohol alkali mixed solution of the 3.0mol/L glycerine that volume ratio is 1:1 and 2.0mol/L potassium hydroxide 45 DEG C clear up 9h after to take the filtrate of supernatant liquid standby；Then catalyst APG, etherifying agent aminoguanidine hydrochloride leucoaurin, guar gum and upper strata filtrate are injected according to the ratio of mass percent respectively 3%, 5%, 32%, 60% and hydrothermal synthesis reaction still is heated to 100 DEG C of reaction 3h, it is cooled to room temperature, filtering reacting liquid body concentrating and precipitating, dry sediment at 45 DEG C and i.e. obtain light fibre flocculation aid solid.
Embodiment two:
Learn from else's experience the cotton stalk after grinding, be heated in the alcohol alkali mixed solution of the 3.5mol/L glycerine that volume ratio is 1:2 and 1.5mol/L potassium hydroxide 50 DEG C clear up 10h after to take the filtrate of supernatant liquid standby；Then catalyst APG, etherifying agent aminoguanidine hydrochloride leucoaurin, guar gum and upper strata filtrate are injected according to the ratio of mass percent respectively 4%, 6%, 25%, 65% and hydrothermal synthesis reaction still is heated to 105 DEG C of reaction 4h, it is cooled to room temperature, filtering reacting liquid body concentrating and precipitating, dry sediment at 50 DEG C and i.e. obtain light fibre flocculation aid solid.
Embodiment three:
Learn from else's experience the cotton stalk after grinding, be heated in the alcohol alkali mixed solution of the 2.5mol/L glycerine that volume ratio is 2:3 and 2.5mol/L potassium hydroxide 55 DEG C clear up 9.5h after to take the filtrate of supernatant liquid standby；Then catalyst APG, etherifying agent aminoguanidine hydrochloride leucoaurin, guar gum and upper strata filtrate are injected according to the ratio of mass percent respectively 5%, 7%, 18%, 70% and hydrothermal synthesis reaction still is heated to 110 DEG C of reaction 3.5h, it is cooled to room temperature, filtering reacting liquid body concentrating and precipitating, dry sediment at 55 DEG C and i.e. obtain light fibre flocculation aid solid.
