Abstract

The invention discloses a biological purification block based on municipal sludge as well as a preparation method and application thereof; the biological purification block is mainly prepared from municipal sludge, functional microorganisms, botanical carbon fiber substances, clay, gypsum residues and magnesium oxide, and functional microorganism strains are Bacillus amyloliquefaciens IAE and Trichoderma asperellum 12. Based on immobilization and implantation of functional microorganisms including bacillus amyloliquefaciens IAE and trichoderma asperellum 12 in municipal sludge, the prepared biological purification block has the capacity of immobilizing and purifying pollutants including nitrogen and phosphorus organic matters, solid suspended particles and the like in a water body, the water body is effectively purified, a large amount of municipal sludge is rapidly digested, and a new way is provided for recycling of municipal sludge.

Description

technical field

[0001] The invention belongs to biological technology, in particular to a biological purification block based on municipal sludge and its preparation method and application Background technique

[0002] The volume of municipal sludge is large. Vigorously promoting the stabilization, harmless and resourceful treatment and disposal of sludge is an important item in the ecological environment protection plan. Conventional treatment measures such as landfill, making building materials, incineration and other measures have relatively little environmental risk and market demand, and it is difficult to consume huge volumes of municipal sludge.

[0003] At present, the construction of sponge city is vigorously promoted, so that the city can absorb, store, infiltrate and purify water when it rains like a sponge, and "release" the stored clean water and make use of it when needed. At present, the utilization of municipal sludge resources in the construction of sponge ...
