Environment-friendly equipment with multistage filtering function for sludge treatment

Abstract

The invention discloses environment-friendly equipment with a multistage filtering function for sludge treatment. The environment-friendly equipment comprises a filtering treatment device, wherein a primary precipitation pool is arranged on the inner surface inside the filtering treatment device; a strong power magnet is fixedly arranged on the inner surface inside the primary precipitation pool;grids are fixedly arranged on the outer surface of one side of the primary precipitation pool. The environment-friendly equipment with the multistage filtering function for sludge treatment is provided with the strong power magnet, the two grids, a methane compressor, a methane storage tank, a combustion furnace, a rolling tube machine and a support spring; metal in the sludge can be subjected toadsorption collection, so that the heavy metal content in the sludge is reduced; the further filtering effect can be achieved, so that the sludge becomes fine and can be easily treated; the fast conveyance and recovery of the methane can be realized; the better environment-protection and energy-saving effects are achieved; the contact area between the sludge and the drying media can be increased;the sealing performance is good; the vibration of the equipment during the operation can be reduced; the abrasion among components is reduced; the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the field of environmental protection equipment for sludge treatment, in particular to an environmental protection equipment with multi-stage filtration for sludge treatment. Background technique [0002] Sludge is composed of solid substances in raw wastewater and solid substances produced during wastewater treatment. Sludge treatment is a process of reducing, stabilizing and harmless treatment of sludge. The higher the concentration, the more sludge residues will be generated to be treated. The current environmental protection equipment for sludge treatment cannot absorb and collect metals in sludge, and cannot reduce the heavy metal content in sludge. The filtering effect is not good enough. It cannot realize the rapid transportation and recovery of biogas, is not environmentally friendly and energy-saving, does not increase the contact area between sludge and drying medium, and has low efficiency during drying treatment, an...

[0002] Sludge is composed of solid substances in raw wastewater and solid substances produced during wastewater treatment. Sludge treatment is a process of reducing, stabilizing and harmless treatment of sludge. The higher the concentration, the more sludge residues will be generated to be treated. The current environmental protection equipment for sludge treatment cannot absorb and collect metals in sludge, and cannot reduce the heavy metal content in sludge. The filtering effect is not good enough. It cannot realize the rapid transportation and recovery of biogas, is not environmentally friendly and energy-saving, does not increase the contact area between sludge and drying medium, and has low efficiency during drying treatment, and cannot reduce vibration during equipment operation and wear between components. Larger, the service life of the equipment is shortened, the functionality is poor, and further improvement is required
