Abstract

The invention belongs to the technical field of environmental protection, and particularly relates to preparation and application of a novel agent, specifically to an agent for deep dehydration of sludge and a preparation method. The agent is formed by compounding the following components in parts by mass: 10 to 20 parts of a soluble ferric salt, 15 to 20 parts of a soluble polymer ferric salt, 1 to 15 parts of a soluble polymer aluminum ferric salt, 15 to 20 parts of a soluble polymer aluminum salt, and 30 to 50 parts of an attaching agent. The agent for the deep dehydration of the sludge and the preparation method for the agent have the advantages that the novel agent for the deep dehydration of the sludge, the preparation method and application are provided; the agent is formed by compounding a plurality of raw materials, so that sludge particles are destabilized, the sludge particles are electrically neutralized, and the sludge is adsorbed, bridged, netted and swept; the agent is good in dehydration effect, environment-friendly and pollution-free; the preparation process for the agent is simple, and is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to the preparation and application of a novel medicament, in particular to a medicament for deep dehydration of sludge and a preparation method thereof. Background technique [0002] With the continuous development of economy and society, the amount of sludge generated also increases. If the sludge cannot be effectively treated and disposed of, it will cause serious pollution to the environment, and will greatly weaken the environmental and social effects of sewage treatment and treatment, directly threatening the human living environment and the food safety of aquatic products. [0003] Sludge is the product of sewage treatment or sewage purification. It is an extremely complex heterogeneous body composed of organic debris, microbial cells, inorganic particles, and colloidal particles. The main characteristics of sludge are high water content (up to 99...
