Sludge treatment method and matched treatment device

Abstract

The invention relates to the technical field of sludge treatment, in particular to a sludge treatment method and a matched treatment device, and the method comprises the following steps: a, collectingwater-containing sludge into the sludge treatment device; b, beating and spraying the interior of the sludge; c, naturally settling; d, separating mud from water; e, performing sludge drying treatment; and f, pressing the semi-dry sludge into building blocks. According to the treatment method, the water-containing sludge can be quickly dewatered and dried, and the sludge treatment effect can be effectively guaranteed; when the sludge is treated, the uniform spreading of the sludge can be effectively realized, and finally, the sludge drying efficiency is improved; the paving thickness of the sludge and the shoveling thickness of the semi-dry sludge can be automatically adjusted, so that the high efficiency of the sludge drying treatment process is further ensured; the sludge is treated toobtain semi-dry sludge, and the semi-dry sludge is finally utilized to form a building block, so that the recycling rate of the sludge can be effectively improved, and the environmental friendliness of sludge treatment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge treatment method and a matching treatment device. Background technique [0002] Sludge is the solid sedimentation material produced by water and wastewater treatment processes. After sewage treatment, some sludge will be produced. If it is not treated in time, it will cause a lot of harm. [0003] Untreated sludge can contaminate ground and surface water. After the erosion and infiltration of rainwater, sludge can easily cause secondary pollution to groundwater. The abundant N and P contained in it enter the surrounding water body or soil, and the excess released N and P enter the surface water along with the water circulation system. cause eutrophication of surface water. [0004] The salt in the sludge will directly affect the electrical conductivity of the soil, destroy the balance of plant nutrients, inhibit the absorption of nutrients by plants, and even...

Problems solved by technology

[0004] The salt in the sludge will directly affect the electrical conductivity of the soil, destroy the balance of plant nutrients, inhibit the absorption of nutrients by plants, and even cause direct damage to the roots of plants, resulting in plant death, and the antagonism between salt ions will make the soil in the soil Effective nutrients accelerate leaching, destroying the balance of soil nutrients, making the soil compact and barren
