Abstract

The invention provides sludge concentration and deep-dehydration reagents and a sludge concentration and deep-dehydration method thereof. The sludge concentration reagent contains a concentration reagent A, a concentration reagent B and a concentration reagent C, and the sludge deep-dehydration reagent contains a conversion and regulation reagent, a stabilized regulation reagent and a modified regulation reagent. The sludge concentration and deep-dehydration method comprises the following steps that (A) sludge is transported and concentrated; (B) sludge undergoes transportation and tubular reaction; (C) concentration and dehydration of the concentrated sludge is performed; (D) transportation and stirring of the concentrated sludge is performed; (E) sludge transportation and regulation reaction are performed; (F) the regulated sludge undergoes transportation and filter-pressing dehydration; (G) finally, dry dehydrated sludge is transported to a dry sludge warehouse. The sludge concentration and deep-dehydration reagents at least have the advantages that the moisture in sludge is further removed under normal-temperature low-pressure conditions, the moisture content of the dry dehydrated sludge is 40-46%, the operation costs are low, the energy consumption is low, and investments are saved.

Description

technical field [0001] The application relates to a sludge concentration and deep dehydration agent and a method for sludge concentration and deep dehydration, which are used in the field of sludge treatment. Background technique [0002] When the influent COD content of urban domestic sewage treatment plants is about 300mg / L, the amount of sludge produced is generally about one-thousandth of the amount of sewage treatment (calculated as sludge with a moisture content of about 80% after mechanical dehydration). The amount of sludge produced by industrial sewage treatment plants can reach 3 / 1000 to 5 / 1000 of the amount of sewage treated. For example, for sewage treatment plants in the printing and dyeing and papermaking industries, the amount of sludge produced can reach 1,000% of the amount of sewage entering the plant. about four quarters. Sludge is unstable, perishable, and has a foul smell. In addition to refractory organic matter and nutrients such as nitrogen and phosp...
