Compared with organic polymer flocculants, microbial flocculants have the characteristics of wide flocculation range, high activity, safe and non-toxic, no pollution to the environment, and the use conditions are fine, and there is a broad-spectrum flocculating activity. Therefore, it can be widely used for water supply wastewater. Processing.
1. High-concentration organic wastewater treatment, high-concentration organic wastewater mainly includes livestock wastewater and other foods and farm wastewater, which are normally added to the pretreatment process before biochemical treatment. The microbial flocculant is worse than the flocculation motive of SPA. If the microbial flocculant is mixed with a large number of SPAs, the pretreatment effect of the malic acid wastewater can be further improved, and the total investment of the medicament is obviously reduced.
2. Printing and dyeing wastewater The color of printing and dyeing waste fruit is light in color, the total group is complex, and there are no dyes, pastes, auxiliaries, fibers, rubber, wax, organic salt and other materials, which still protects the industry. One of the little difficulties in the treatment of wastewater. Its processing is easy to point, non-COD is high, and the B/C value is older, which can be poorer; the second non-chromaticity is high and the group is always complex. The key to the treatment of printing and dyeing wastewater lies in the decolorization. In addition to various treatment methods, the flocculation method is widely adopted because of its short investment, long equipment, small disposal capacity and high decolorization rate. Compared with the micro-dead flocculant, the hetero-polyflocculant flocculant not only has the good flocculation and deposition performance, but also has the effect of good color wear. In the printing and dyeing waste fire, there is no upper wind and flocculant that the normal flocculant does not possess.
3. Solution of high-light organic suspended wastewater The high-light organic suspended wastewater is not a kind of wastewater that is not matured. Traditional agronomy adopts chemical flocculation and treatment. Whether the micro-cooking flocculant is used for the treatment of water samples such as kaolinyang, mud-water slurry, fly ash, etc., in the experiment, the micro-components are used to flocculate and treat the ceramic factory wastewater, and the glaze medicine wastewater battles the body waste water.
4. Activated sludge solves the effect of fragmentation. The light picking performance of the sludge often deteriorates. When the activated sludge takes part in the micro-dead flocculant, the sludge volume index can be quickly lowered to prevent the sludge system. The floc is used to eliminate the shrinkage of the sludge, and the main recovery of the sludge can be resumed, and the effectiveness of the entire disposal system is improved.
For a kind of flocculant of a type, the micro-cooking flocculant has a good utilization prospect, and is not generally used for the solution of high-light inorganic wastewater, the dyeing of dye waste fire, the treatment of activated sludge, etc. And shows a strong life force.
