Problems solved by technology

It is a thick substance between liquid and solid, which can be transported by pump, but it is difficult to separate solid and liquid by settling
[0003] Severely polluted sludge contains a variety of heavy metals, organic matter and other pollutants, which seriously restricts the follow-up treatment of sludge
In related technologies, sludge treatment agents are used to treat sludge. For heavily polluted sludge, the treatment effect is limited, and the pollutants cannot be stably solidified. The pollutants contained in the treated sludge are still easy to Diffusion into the environment, and the consumption of required sludge treatment agent is large, and the treatment process is cumbersome; in addition, the use of sludge treatment agent often causes changes in the pH value of sludge, which affects the physical properties, chemical properties and Ecological activity has a significant impact, which will have a direct impact on the further disposal of the sludge

Abstract

The invention provides a curing agent as well as a synthesis method and application thereof. The curing agent provided by the invention is mainly synthesized by utilizing a porous mineral material, an organic flocculating agent and a conductive agent at a specific dosage ratio; the synthesis method has a simple technology and is suitable for large-scale production; the curing agent provided by the invention can be used for effectively treating serious pollution sludge, and rapidly and effectively adsorbing and locking and fixing pollutants in the sludge, so that the pollutants are difficultly released into an environment outside the sludge and the harmless effect is realized; the cured sludge is of a fluffy aggregate structure, so that the cured sludge has very good air permeability and subsequent continuous fermentation is convenient to realize; moreover, the curing agent does not change the pH (Potential of Hydrogen) value of the sludge and does not influence the physical property, the chemical property and the ecological activity of the sludge; the treated sludge can be regenerated and repeatedly utilized.

Description

technical field [0001] The invention relates to the field of environmental governance, in particular to a curing agent and its synthesis method and application. Background technique [0002] Sludge is the solid sediment produced by water and sewage treatment processes. The main characteristics of sludge are high water content (up to 99%), high content of organic matter, easy to rot and smell, and the particles are finer, the specific gravity is smaller, and it is in a colloidal liquid state. It is a thick substance between liquid and solid, which can be transported by pump, but it is difficult to separate solid and liquid by sedimentation. [0003] Severely polluted sludge contains a variety of heavy metals, organic matter and other pollutants, which seriously restricts the follow-up treatment of sludge. In related technologies, sludge treatment agents are used to treat sludge. For heavily polluted sludge, the treatment effect is limited, and the pollutants cannot be stabl...
