Abstract

The invention discloses a conditioning modifier for water supply plant sludge, a sludge material as well as a preparation method and application of the sludge material. The conditioning modifier for the sludge of the water supply plant comprises the following components in parts by weight: 100 parts of regenerated micro powder; 8 to 36 parts of attapulgite; the fineness of the attapulgite is 180 to 360 meshes; 3-9 parts of a coupling agent; 3-7 parts of a water repellent; 2 to 6 parts of water-absorbent resin; and 1.5 to 4.0 parts of an oxidizing agent. Through mutual cooperation of specific components, the prepared conditioning modifier is used for conditioning and modifying the sludge of the water supply plant to obtain modified sludge, and the modified sludge can be used as planting soil and an inorganic binder, and has relatively high germination rate and compressive strength, so that resourceful treatment of the sludge of the water supply plant is realized, and the resource utilization rate of the sludge of the water supply plant is improved. The material with multiple purposes is obtained while environmental pollution is solved, and the method has remarkable progressive significance.

Description

technical field [0001] The invention relates to a conditioning modifier for sludge in a water supply plant, a sludge material, a preparation method and application thereof. Background technique [0002] Urban water supply and drainage facilities play a pivotal role in the development of urban modernization. It is an important prerequisite for protecting the human living environment and improving people's material living standards, and is one of the important symbols to measure the level of modern cities. Due to the high content of organic matter in sludge from sewage plants, energy recovery is mainly used at home and abroad, and the resource utilization technology is relatively mature. In contrast, water supply plant sludge has low organic matter content and low energy recovery value. At present, it is mainly treated by landfill, which not only occupies land, pollutes the environment, but also produces a large amount of fugitive greenhouse gases. Research on resource utiliz...
