Agent and preparation method thereof.
Background technique
It is sharply increased with the rapid development of industry with population, cities and towns drink earth's surface water demand and industrial wastewater, city
City's sanitary sewage, breeding wastewater discharge amount are growing day by day.Since sewage discharge type constantly rises, water pollutant ingredient becomes
It becomes increasingly complex, therefore the difficulty handled sewage is also increasing.It, can be to industrial and agricultural production and people if dealt with improperly
Class health is to seriously threatening.State lives the portion's of building notification and explicitly points out, and increases specific resistance to filtration working dynamics into next step work
Make emphasis, target is to the year two thousand twenty bottom, and ground level and the above municipal sludge harmlessness disposing rate reach 90%, other cities reach
75%；Strive reaching 60% in county town.
More commonly used in industry at present is to carry out flocculation treatment to water-containing sludge using polyacrylamide (abbreviation PAM).
But because mud, water can be coated togather simultaneously by its covering property, even if causing to be added to the auxiliary materials such as stalk during later stage fermentation
And strain can not also make sludge really be fermented.Since sludge is under anaerobic state always, it is not suitable for depositing for bacterium
It is living, so resulting in the mortality of strain；Longer drying cycle makes the organic matter transformation in sludge for ammonia, vulcanization
The gases such as hydrogen, alkanes are largely lost, and the stench constantly issued has also seriously affected surrounding enviroment.
Biological flocculant refers to various functional protein, functional polysaccharose substance with flocculation activity, it micro-
Seeing stereochemical structure mainly includes fibrous structure and chondritic, its flocculation mechanism mainly includes bridge linking effect, neutralization
With the volume effect of sweeping.Effectively overcome that inorganic flocculating agent and artificial synthesized organic flocculant are existing in terms of safety and environment to ask
Topic, is environmentally friendly green flocculant, the increasingly attention by various countries water treatment work person.
