Abstract

The invention discloses a ceramic wastewater treatment method and a ceramic wastewater treatment device, which are characterized in that ceramic wastewater is collected in a wastewater settling pond firstly, so that large granular solids are settled in the wastewater settling pond; then, wastewater subjected to preliminary settling is pumped to an efficient precision treater to be filtered through a wastewater pump; clean water produced by filtering is conveyed to a clean water pond to reuse; after filtered objects accumulated by the efficient precision treater reach a certain amount, back-wash clean water is fed into the efficient precision treater, and sludge washed out is guided into a sludge pool. Compared with existing technologies, the ceramic wastewater treatment method and device disclosed by the invention have an advantage of efficiently, rapidly and reliably purifying ceramic wastewater.

Description

Technical field:

[0001] The invention relates to a wastewater treatment method and device. Background technique:

[0002] Wastewater in the ceramic industry is mainly produced during the production process of ball milling (ball washing), filter press cloth cleaning, glazing (cleaning), spray drying, edging and polishing, etc. It also brings a certain amount of high turbidity and high suspended solids wastewater. Although the concentration of organic matter in this type of wastewater is low, some materials enter the water during the production process of each process, resulting in a maximum concentration of suspended solids in the drainage up to 5000mg / L or more. It belongs to high turbidity production wastewater. Part of the suspended particles in the wastewater is very small, and the suspended solids in the wastewater are mainly solid particles with a particle size of <150 Ξm. The proportion is very large, which is close to the diameter of colloidal ions. It is diff...
