Abstract

The invention provides a biocompatible hydrophilic magnetic sludge fine aggregate carrier. The carrier is at least prepared from components in parts by weight as follows: 10-60 parts of silt or sludge, 10-50 parts of fly ash, 10-60 parts of cement, 4-20 parts of lime, 1-15 parts of gypsum, 2-30 parts of clay, 0-10 parts of an activator, 0-15 parts of a binder, 0-15 parts of a pore-forming agent, 0-20 parts of magnetic powder, 0-10 parts of a biocompatible substance and 0-10 parts of a hydrophilic agent. The invention further provides a preparation method of the fine aggregate carrier. According to the fine aggregate carrier, intractable solid waste such as the silt, the sludge, the fly ash and the like is consumed, a reliable way is provided for treatment of the solid waste such as the silt, the sludge and the fly ash, problems that biological carriers are poor in biocompatibility, poor in microorganism promotion and activation effect, insufficient in hydrophilic performance and sewage treatment effect and the like are solved, and the prepared fine aggregate carrier has the advantages of good mechanical property, high in biofilm forming speed, good in biological hydrophilic performance and sewage treatment effect and the like.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a bio-affinity and hydrophilic magnetic sludge clay sand carrier, and also relates to a preparation method of the carrier. Background technique [0002] Dredging mud is a kind of waste that occurs in large quantities, and the disposal of mud will pollute the environment. In the Pearl River Delta region of my country, the annual dredging mud usually reaches 80 million m 3 about. In order to improve the improvement of rural rivers, Jiangsu Provincial Finance issued the first batch of 370 million yuan for rural river improvement in July 2012, including 190 million yuan for county and township river dredging, 180 million yuan for village river and pond improvement, and 360 million m3 of dredging and improvement earthwork 3 . In the east route project of the North-South Water Diversion Project, the cost of land acquisition for the dredged silt reached 64...
