Abstract

The invention discloses a preparation process of a sludge pretreatment agent for sludge treatment, and belongs to the technical field of pretreatment agent preparation. The preparation process comprises the following steps of: S110, preparing a deoiling agent: selecting 1%-35% by mass of a component A, 15%-30% by mass of a compound surfactant and the balance water, and directly and uniformly mixing the substances to prepare the deoiling agent; S120, preparing modified activated carbon powder; S130, preparing tea powder, namely selecting tea leaves at the bottom layer of a tea tree, performingdrying in the sun, and conducting grinding into powder; S140, preparing a flocculating agent; S150, preparing modified bentonite; S160, preparing modified zeolite powder; and S170, preparing the sludge pretreatment agent. Grease activity is activated by adopting the deoiling agent, grease is separated from sludge, and the grease carries impurities dissolved in the grease during separation, so thatthe effect of purifying the sludge is achieved; after the viscosity of the sludge is reduced by the tea powder, the sludge is quickly separated from harmful substances dissolved in the sludge.

Description

Technical field[0001]The invention relates to the technical field of preparation of pretreatment agents, in particular to a preparation process of a sludge pretreatment agent for sludge treatment.Background technique[0002]In the process of water treatment in domestic urban sewage treatment plants, a large amount of solid waste such as sludge is formed. Among them, nearly 10 million tons of dry sludge needs to be treated for harmless treatment and resource utilization after probation. In addition to the large amount of river bottom sludge and lake bottom sludge affected by sewage discharge, environmental protection and harmless treatment and cleaning of the river and lake bottom sludge are required. At present, the total amount of sludge that needs to be treated, disposed and recycled in my country is nearly 100 million tons. (Wet sludge), these solid wastes must be timely and effectively treated in an environmentally friendly and harmless manner and recycled; they need to be treated...
