Description
Technical Field
The invention relates to the field of water treatment medicaments, in particular to a preparation method of a natural composite organic flocculant of moringa seed meal.
Background
The organic flocculant is natural or synthetic organic molecular substance capable of generating flocculation, and natural product is protein or polysaccharide compound, such as starch, protein, animal glue, sodium alginate, sodium carboxymethyl cellulose, etc.; the synthetic products include polyacrylamide, sodium polyacrylate, polyvinyl pyridinium, polyethyleneimine, etc. The flocculant (coagulant) is a water-soluble linear polymer substance, and most of the flocculant (coagulant) can be ionized in water and is a polymer electrolyte. According to their dissociable group characteristics, they can be classified into anionic, cationic, and amphoteric; the chain molecules can generate bonding and bridging effects, and charged groups on the molecules play a role in electrically neutralizing and compressing a diffusion layer of the micelle. Because of the relatively high price of high molecular coagulants, they are often used in wastewater treatment for special purposes such as high concentration, high turbidity, high color and special odor.
The natural plant flocculant has long been used for purifying water, for example, residents in Africa and the like directly dry mature seeds and then dehulled, crushed, sieved, stirred with water, and the supernatant obtained by filtering can be directly used for purifying drinking water. The moringa seed protein has the advantages of higher protein content, no toxicity or side effect, safety and benefit for biodegradation, and can be used for water supply purification or wastewater pretreatment. However, the treatment effect of the coarse treatment and the single moringa seed flocculant does not reach the best level, and the moringa seeds also contain a large amount of fat substances, and the subsequent flocculation is negatively affected if the coarse treatment and the single moringa seed flocculant are not removed.

It can greatly shorten reaction time, reduce precipitation time, quicken filtration speed and reduce medicament cost.
In addition, sodium Alginate (SA), also known as algin, is a polyanionic polysaccharide carbohydrate extracted from kelp of brown algae or gulfweed. The linear polymer structure can penetrate through a water film, and a chelating network structure is formed by the functional groups such as hydroxyl, carboxyl and the like contained in the linear polymer structure and metal ions and polymers thereof in the flocculant, so that the electric neutralization effect of the flocculant is exerted, and the net capturing effect of the cross-linking network structure is exerted, and the flocculation efficiency is improved. Therefore, SA can be theoretically used as a natural polymer coagulant aid.

The difference compared to example 1 is that step (3) is omitted. Adding 5ml of flocculant into 200ml of kaolin suspension (turbidity 200 NTU) and stirring at 500rpm at normal temperature for 0.3h, and standing for 1.5h, wherein the turbidity removal efficiency reaches 91.45%.
Therefore, the moringa protein in moringa seed meal, anions, proteins and fiber substances in MR agaric glue are matched, and linear macromolecules in sodium alginate can provide adsorption bridging effect to obtain better flocculation effect, the turbidity removal efficiency is 92-96%, the removal rate is about 4-8 times of that of Shan Lamu seed meal flocculant, and the cost can be reduced, the flocculation time can be shortened and the effluent quality can be improved when the treatment efficiency of the monomer flocculant is improved. And the flocculant is prepared from plants with less environmental pollution, so the flocculant is environment-friendly, nontoxic, harmless and degradable.
