DEVICE TO TREAT INDUSTRIAL WASTES AND EFFLUENTS Russian patent published in 2011 - IPC C02F1/46 C02F9/06 

FIELD: process engineering.

SUBSTANCE: invention relates to environmental protection and may be used for treatment of effluents and wastes. Proposed device comprises dehydration scraper conveyor, crosswise partitions, process water cleaning devices of two types, water electrical cleaning devices and device to adjust water bleed and discharge depth. Water cleaning devices are arranged in inclined trench that water flow at 0.35±0.10 m/s-rate. Said scraper conveyor is arranged at trench bottom to discharge dewatered slurry into filtration hopper. Water cleaning device are arranged in pairs, that is, louvers-type cleaner - electrical cleaner, and lengthwise finely-dispersed precipitation module - water electrical treatment module, total number of pairs making 6-12. Note here that electrical treatment modules voltage between electrodes varies with distance there between to make 2.5±0.5 V/cm and adjacent pair electrodes polarity being opposite. Positive potential of 10-12 V is fed to crosswise electrically conducting filter while negative potential is fed to scraper conveyor casing.

EFFECT: reduced costs and higher reliability.
