Abstract

The invention discloses an organic sludge conditioning agent. The organic sludge conditioning agent is prepared from, by weight, 20-35% of alkane-series amine salt compound, 2-8% of polyamine-type polymer and 55-70% of ferric-series inorganic salt. When the organic sludge conditioning agent is mixed with sludge to form floc sludge, the situation that dewatering filter cloth is clogged when the clustering viscosity of the glue-feather sludge is too large is avoided; besides, when the glue-feather sludge generated after conditioning is squeezed under pressure, influences on moisture releasing due to deformation and structural damage cannot be caused, and thus the dewatering effect is achieved; meanwhile, a large amount of extra deposit cannot be generated, so that the situation that the sizeof finally to-be-removed sludge is increased due to deposit derived from the agent during dewatering cannot occur; therefore, the size of the sludge can be greatly reduced, and the removing cost is lowered at the same time.

Description

technical field

[0001] The invention relates to the field of waste treatment, in particular to an organic sludge conditioning agent and an organic sludge dehydration method using the agent. Background technique

[0002] At the end of the existing organic sewage treatment, after various purifications, the substances in the sewage are settled and sludged, and the sludge must be removed, treated, and disposed of. The price of cleaning and transportation is calculated based on the weight of sludge. Therefore, the greater the weight of sludge, the higher the cost of cleaning and transportation. If the water content of the overall sludge can be reduced through effective dehydration, it will help reduce the weight of the sludge, thereby reducing the cost of sludge removal and transportation.

[0003] As far as the applicant knows, the common way to reduce the water content of organic sludge is to separate the water and solid matter in the sludge through centrifugation. , or addin...
