Chemical sludge concentration treatment device and treatment process thereof

Abstract

The invention belongs to the technical field of sludge treatment, and particularly relates to a chemical sludge concentration treatment device, which comprises a chemical sludge pool, wherein one endof the bottom of the chemical sludge pool downwards sinks; the downwards sinking position inside the chemical sludge pool is connected with a precipitation pool through a first pipeline; a water pumpis arranged on the first pipeline; a stirring device is arranged in the side surface position of the middle height of the precipitation pool; an inclined plate is arranged at the bottom of the precipitation pool; a plurality of sludge leaking holes are uniformly formed in the inclined plate; a position sensor is arranged on the middle part of the inclined plate; a second pipeline communicated withthe precipitation pool is arranged under the precipitation pool; an electromagnetic valve is arranged on the second pipeline; a sludge mixing pool is arranged right under the second pipeline; a watercollecting well is communicated with the top of the precipitation pool through a pipeline; the sludge mixing pool is communicated with a plate frame press filter through a pipeline with a second water pump; the outlet end of the plate frame press filter is connected with a water collecting well through a pipeline; a control system is respectively and electrically connected with the water pump, the position sensor and the stirring device. The invention also provides a treatment method of the chemical sludge concentration treatment device.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a chemical sludge concentration treatment device and a treatment process thereof. Background technique [0002] At present, in the recycled paper and papermaking industry, with the triple requirements of policy, economy and environmental protection, enterprises need to implement clean production, energy saving and emission reduction. The content of organic matter with high concentration and refractory biodegradation is increasing, and the current biochemical treatment process commonly used at home and abroad can no longer meet the discharge water discharge standard, so the advanced treatment system is widely used. However, improper chemical sludge concentration treatment will lead to high water content after concentration, which does not meet the requirements of sludge concentration in the subsequent sludge treatment system, increases the volume occupancy rat...

Problems solved by technology

[0002] At present, in the recycled paper and papermaking industry, with the triple requirements of policy, economy and environmental protection, enterprises need to implement clean production, energy saving and emission reduction. The content of organic matter with high concentration and refractory biodegradation is increasing, and the biochemical treatment process commonly used at home and abroad can no longer meet the discharge water discharge standard, so the advanced treatment system is widely used

However, improper chemical sludge concentration treatment will lead to high water content after concentration, which does not meet the requirements of sludge concentration in the subsequent sludge treatment system, increases the volume occupancy rate of the sludge tank, and reduces the operation of the sludge treatment system. efficiency
