Embodiment 1

[0009] Take the ground and pulverized corn stalks, heat to 60°C in a mixed solution of 1.5 mol / L ethylene glycol and 2.0 mol / L sodium hydroxide with a volume ratio of 1:3, soak for 6 hours, and then take the filtrate and filter residue for later use; then the filtrate , flax glue, catalyst and filter residue were injected into the hydrothermal synthesis reaction kettle according to the mass percentage of 40%, 28%, 5% and 27%, heated to 115°C, reacted at 1.5MPa for 4h, cooled to room temperature, and took the upper layer The liquid is concentrated and precipitated, and the precipitate is dried at 40°C to obtain a light coupling coagulant solid. The catalyst is trialkyl ammonium chloride.

Embodiment 2

[0011] Take the ground and pulverized corn stalks, heat to 65°C in a mixed solution of 2.0mol / L ethylene glycol and 2.5mol / L sodium hydroxide with a volume ratio of 2:3, soak for 7 hours, and then take the filtrate and filter residue for later use; then the filtrate , flax glue, catalyst and filter residue were injected into the hydrothermal synthesis reaction kettle according to the mass percentage of 41%, 25%, 6% and 28%, heated to 120°C, reacted at 2.0MPa for 5h, cooled to room temperature, and took the upper layer The liquid is concentrated and precipitated, and the precipitate is dried at 45°C to obtain a light coupling coagulant solid. The catalyst is dodecyltrimethylammonium chloride.

Embodiment 3

[0013] Take the ground and pulverized corn stalks, heat to 70°C in a mixed solution of 2.5 mol / L ethylene glycol and 3.0 mol / L sodium hydroxide with a volume ratio of 1:2, soak for 8 hours, then take the filtrate and filter residue for later use; then the filtrate , flax glue, catalyst and filter residue were injected into the hydrothermal synthesis reaction kettle according to the mass percentage of 45%, 17%, 8% and 30%, heated to 130°C, reacted at 1.8MPa for 6h, cooled to room temperature, and took the upper layer The liquid is concentrated and precipitated, and the precipitate is dried at 50°C to obtain a light coupling coagulant solid. The catalyst is dimethyl diallyl ammonium chloride.

Abstract

The invention belongs to the technical field of environmental protection and relates to an environment-friendly light coupling coagulant aid. The light coupling coagulant aid is prepared from, by mass, 40-45% of a corn stalk alcohol-alkaline filtrate, 17-28% of flax gum, 27-30% of corn stalk alcohol-alkaline filter residues and 5-8% of a catalyst. Due to the fact that the light coupling coagulant aid adopts corn stalks as a main synthesis raw material, the novel way for current corn stalk resourceful treatment and comprehensive utilization is expanded, natural material and energy circulation is achieved, environmental protection is facilitated, and the good social, environmental and economic benefits can be obtained.

Description

technical field [0001] The patent of the invention belongs to the field of environmental protection technology, and specifically relates to the synthesis of a lightweight coupling coagulant by using corn stalks and flax glue as raw materials. Background technique [0002] Corn stover is a by-product of the agricultural production process. Before the modern scientific methods and awareness of using straw have not been established, the excess straw is becoming a source of pollution in the rural ecological environment, deteriorating the rural living environment and exacerbating the pollution of the agricultural environment. Therefore, using corn stalks as raw materials to synthesize coagulant aids is a new way for comprehensive utilization of straw. [0003] At present, the resource utilization of corn stalks mainly includes straw fertilization, straw feed, straw fermentation to produce biogas, and straw briquette fuel, etc., but these technical methods are very easy to genera...
