| titleOfInvention | An inorganic polymer sludge conditioner and its preparation method and application |
| abstract | The invention relates to environmental pollution control materials, and specifically discloses an inorganic polymer sludge conditioner and a preparation method and application thereof. Through the selection of raw materials and the optimization of the preparation process, the invention develops an inorganic polymer sludge conditioner with an Alb content greater than 50% and a total Alb+Alc content greater than 80%, which can be applied to the field of sludge treatment. Since the inorganic polymer sludge conditioner described in the present invention has a prefabricated aggregated form, after being added to the sludge system (excess sludge or anaerobic digested sludge), it can be combined with LB-EPS (closely bound cells) outside the sludge cells. External polymer) combined to reduce the capillary water absorption time (CST) of the sludge and enhance the dewatering performance of the sludge. At the same time, the inorganic polymer sludge conditioner product of the present invention is a pure liquid product with moderate pH, which overcomes the large increase rate of sludge dry solids in the traditional lime+FeCl conditioning process, the strong alkalinity of the sludge after conditioning, and the difficulty in The problem of subsequent utilization has a good prospect of promotion and application. |
