Abstract
An efficient sludge dehydration agent is disclosed. The dehydration agent comprises acrylamide, acryloyloxyethyltrimethyl ammonium chloride, a polymerization auxiliary agent, urea, azodiisobutyronitrile, deionized water, an initiator and a reducing agent. The dehydration agent has good solubility and can be dissolved in water rapidly. Flocs formed by biochemical sludge treatment in a sewage factory are large and rapid in settlement. The dehydration agent is high in water yield and increases the sludge treatment efficiency.
Description
Technical field
The present invention relates to a kind of dewatering agent, particularly relate to a kind of High Efficiency Agent of Sludge Dehydration.
Background technology
Municipal sewage plant produces a large amount of mud in the process of disposing of sewage, and because moisture percentage in sewage sludge is very high, will take too large space, and the transportation cost of mud can improve greatly if do not processed.Therefore, the volume sludge dewatering treatment of Sewage Plant is most important.
Usually, these Organic Sludge army things are made up of the colloidal solid that wetting ability is electronegative, and granular size is very uneven and very tiny, and contractibility is large, and specific filtration resistance resistance value is also large, thus filter dehydration poor-performing.Need to add sludge dehydrating agent before mechanical sludge dewatering to nurse one's health, improve its filter dehydration performance, reduce cost of water treatment, improve purifying water effect.Therefore, in process, sludge dehydrating agent is used to become a kind of trend at cities and towns tap water, process water, trade effluent and municipal effluent.
At present, domestic researchist has carried out more concern to sludge dehydrating agent, and be engaged in the study on the synthesis of corresponding laboratory stage, but China exploitation sludge dehydrating agent kind few, yield poorly, unstable properties, the dewatering agent product of present stage sewage disposal station-service depends on imported product.Therefore, the sludge dehydrating agent product that independent research is new and effective has important practical significance.
