Chemical deodorization method for sludge

Abstract

The invention discloses a chemical deodorization method for sludge. The method comprises steps as follows: to-be-treated sludge is put in an adjusting tank, the water content of the to-be-treated sludge is adjusted, the sludge in the adjusting tank is pumped into a reaction tank, a high ferrate solution is added to the reaction tank, the sludge in the reaction tank is stirred, quick lime and a surfactant are added to the reaction tank, the sludge in the reaction tank is continuously stirred, the sludge in the reaction tank is pumped into a dewatering tank, diatomite and zeolite are added to the dewatering tank, the sludge in the dewatering tank is stirred and settled in the dewatering tank, a liquid supernatant obtained after settlement is discharged into a water storage tank, dewatering treatment is performed through sludge dewatering equipment, discharged water is conveyed to the water storage tank, discharged sludge is conveyed to a mud tank, and mud conveyed into the mud tank is taken out and transported from the mud tank after being left to stand for specified time. The sludge deodorization effect is effectively improved, so that sludge is effectively utilized, pollution of sludge to the environment is reduced, and the application value of sludge is increased.

Description

technical field [0001] The invention relates to a sludge treatment method, in particular to a sludge chemical deodorization method, which belongs to the technical field of sludge treatment. Background technique [0002] Sludge is a solid sedimentary substance produced in the process of water and sewage treatment. It is a product of sewage treatment. The main characteristics of mud are high water content, which can be as high as 99%, high organic matter content, easy to rot and smell, and the particles are relatively fine, the specific gravity is small, and it is in a colloidal liquid state. It is a thick liquid between liquid and solid. It can be transported by pump, but it is difficult to separate solid and liquid through sedimentation; most of the sludge also produces odor, which seriously pollutes the environment, which greatly reduces its application value. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention pr...

The main characteristics of mud are high water content, which can be as high as more than 99%, high organic matter content, easy to rot and smell, and the particles are finer, the specific gravity is smaller, and it is in a colloidal liquid state. It is a thick layer between liquid and solid. It can be transported by pump, but it is difficult to separate solid and liquid by sedimentation; most of the sludge also produces odor, which seriously pollutes the environment, which greatly reduces its application value
