Problems solved by technology

In this method, the grit chamber and the sedimentation tank not only occupy a large area and have low efficiency; the conditioning and modification method is to directly add the mud after adding the drug to the conditioning tank through a pump or gravity pressure, as for the mud added to the conditioning tank How to react effectively, how to prevent sedimentation and compaction during the reaction process, and how to further adjust the concentration of mud during the reaction are all issues that we need to discuss; the sludge pollutants with high organic matter are transferred to the north, and the pollutants have not been fundamentally reduced. It also affects the effect of sludge dewatering

Abstract

The invention relates to an integrated rapid treatment system for organic sludge. The system comprises an impurity removal unit, a sludge oxidation unit, a rapid sludge concentration unit and a rapidsludge dehydration unit, wherein the impurity removal unit is used for removing garbage impurities in slurry; the sludge oxidation unit is used for reducing the organic matter content of the sludge and destroying extracellular polymers in the sludge through strong oxidation; the rapid sludge concentration unit is used for accelerating the sedimentation of particulate matters through a flocculatingagent, then realizing rapid separation of sludge and water and further reducing the moisture content of the sludge; the rapid sludge dehydration unit is used for generating a gel substance on the surface of sludge particles through an efficient sludge modifier to form an irreversible condensation hardened shell, so that the sludge particles are of certain water stability and strength stability, the moisture content of the sludge is reduced, and the moisture content of a sludge cake is not more than 40% through mechanical means. The system is simple, convenient to operate and maintain, small in occupied area and short in treatment period, and harmlessness, reduction and stabilization treatment of organic sludge can be quickly realized.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an integrated rapid treatment system for organic sludge. Background technique [0002] With the advancement of social science and technology, the pollution of rivers, lakes and other water bodies is serious, especially the river sediment. The river sediment is not only a "sedimentary reservoir" for accumulating and decomposing pollutants in the river water body, but also releases organic pollutants and pollutants to the overlying water body. The "source" of nutrient salts contains a large amount of polluting substances, especially persistent refractory organic substances that cause disease (cancer), destroy ecology, and heavy metal ions that seriously exceed the standard. These harmful substances will affect human health and damage the natural environment and ecosystem through the accumulation and expansion effect of the food chain. The sediment pollution of riv...
