Embodiment 1

[0037] This embodiment provides a method for preparing the waste residue extract. The waste residue extraction obtained according to the method mainly contains amylopectin, and the amylopectin can be used in the sewage treatment process. The method comprises the steps of:

[0038] Step 1: Take the freshly steamed dregs and grind it into a paste with a rolling juicer while it is still wet. It is advisable to disperse the pasty grains in clear water to form a suspension that is easy to stir, then add sodium carbonate to adjust the pH of the suspension to 9, and soak for 2 hours at a speed of 300r / min to obtain an alkali foam.

[0039] Step 2: Filter the alkali bubble solution with gauze to obtain the first filter residue and the first filtrate. Put the first filter residue back into clean water to form a suspension, soak it for 4 hours under the condition of 150r / min to obtain a blister solution, and filter the blister solution with gauze to obtain a second filtrate and a secon...

Embodiment 2

[0043] This embodiment provides a method for preparing the waste residue extract. The waste residue extraction obtained according to the method mainly contains amylopectin, and the amylopectin can be used in the sewage treatment process. The method comprises the steps of:

[0044] Step 1: Take the freshly steamed dregs and grind it into a paste with a rolling juicer while it is still wet. It is advisable to disperse the pasty discarded grains in clear water to form a suspension that is easy to stir, then add sodium carbonate to adjust the pH of the suspension to 10, and soak for 5 hours at a speed of 250r / min to obtain an alkali foam.

[0045] Step 2: Filter the alkali bubble solution with gauze to obtain the first filter residue and the first filtrate. Put the first filter residue back into clean water to form a suspension, soak it for 3 hours under the condition of 160r / min to obtain a blister solution, and filter the blister solution with gauze to obtain a second filtrate ...

Embodiment 3

[0049] This embodiment provides a method for preparing the waste residue extract. The waste residue extraction obtained according to the method mainly contains amylopectin, and the amylopectin can be used in the sewage treatment process. The method comprises the steps of:

[0050] Step 1: Take the freshly steamed dregs and grind it into a paste with a rolling juicer while it is still wet. It is advisable to disperse the pasty grains in clear water to form a suspension that is easy to stir, then add sodium carbonate to adjust the pH of the suspension to 12, and soak for 8 hours at a speed of 200r / min to obtain an alkali foam.

[0051] Step 2: Filter the alkali bubble solution with gauze to obtain the first filter residue and the first filtrate. Put the first filter residue back into clean water to form a suspension, soak it for 2 hours under the condition of 180r / min to obtain a blister liquid, and filter the blister liquid with gauze to obtain a second filtrate and a second f...

Abstract

The invention discloses the application of waste waste extracts in sewage treatment, and relates to the technical field of comprehensive utilization of waste waste. The application of the discarded grains extract in sewage treatment includes the following steps: preparing the discarded grains extract; polymerizing the discarded grains extract with acrylamide to prepare a sewage flocculant; adding the sewage flocculant into the sewage and stirring evenly After standing still for sedimentation, the solid particles in the sewage are flocculated and precipitated to realize the treatment of sewage. The invention provides the application of waste waste extract in sewage treatment, expands the application idea of ​​waste waste, promotes the rational utilization of waste waste, avoids resource waste and environmental pollution, thereby improving social and economic benefits; provides a sewage flocculant The preparation method can effectively avoid the monomer polymerization of acrylamide and improve the utilization rate of raw materials; the prepared flocculant has large flocculation particles, fast settling speed, branched chain structure, avoids dispersion protection, and has good flocculation effect. It is easy to degrade and does not produce secondary pollution.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of waste waste, in particular to the application of waste waste extract in sewage treatment. Background technique [0002] Distilled grains are the residues of sorghum, wheat, corn, grains, etc. after solid-state fermentation and distillation to extract alcohol. After the solid state fermentation process, some nutrients in the raw materials are consumed, but starch (10%-13%), protein (10%-16%) and fat (3.83%-8.04%), crude fiber and crude fiber are still left in the waste. (18.0%-24.0%) and a large amount of amino acids, abundant inorganic elements such as phosphorus and potassium, and trace beneficial ingredients such as ribonucleic acid and purine produced by microbial cells. According to incomplete statistics, my country's liquor brewing industry produces about 30 million tons of waste every year. Liquor dregs have high acidity and moisture content above 65%. They are easily ...
