Abstract

The invention relates to the technical field of environmental engineering, in particular to a method for cultivating activated sludge from dry sludge. The method comprises the following production steps: S1) preparing before cultivation; S2) sludge preparation: selecting similar new dry activated sludge, preserving the sludge for 15 days under a moisturizing condition, putting the sludge into a biochemical pool, and keeping the mass concentration of the sludge in the biochemical pool to be about 1500mg / L; S3) adding a carbon source; and S4) culturing the sludge in a certain culture environment. The method for cultivating the activated sludge by using dry sludge has the advantages that the operation is simple, the ecological environment is improved, the harmless treatment of domestic sewageis realized, the unification of environmental benefits, economic benefits and social benefits is realized, and the market prospect is wide.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a method for cultivating activated sludge from dried sludge. Background technique [0002] With the continuous development of social economy, our country is gradually facing the situation of water shortage. Generally speaking, when pollutants are discharged into waters such as rivers and lakes, after their own decomposition and the promotion of the environment, the water body can basically return to its original state. However, this self-purification function is extremely limited, and water pollution will occur when pollutants exceed the self-purification capacity of the water body. Therefore, people must intensify efforts to promote sewage treatment and recycling of water resources. The new project of Heping No. 2 Sewage Treatment Plant in the comprehensive renovation of the Lianjiang River Basin came into being under this background. [0003] Sewage treatm...
