Description

Working Principle

The inclined tube and inclined plate precipitation water purification method is formed by placing the sludge suspension layer above the inclined tube inclined plate with an inclination angle of 60 degrees, so that the suspended matter in the raw water accumulates on the bottom surface of the inclined tube. After that, a thin mud layer is formed, which slides back to the mud slag suspension layer after relying on the action of gravity, and then sinks into the mud collecting bucket, and then is discharged into the sludge pool by the mud discharge pipe for treatment or comprehensive utilization. The clean water above will gradually rise to the water collection pipe for discharge, which can be directly discharged or reused. Lamella clarifier separates solids from a carrying liquid by directing the material between a series of inclined plates (sometimes referred to as lamellae).The plates, arranged in close proximity, divide the lamella tank into several integral sections or chambers. Only one side of each chamber, the top surface of a plate, provides a settling surface.The pretreated feed stream enters the lamella tank and transverses through feed ducts longitudinally, along each side of the lamella plates, through a bottomless distribution duct.The liquid and solids feed stream then enters each plate chamber near the bottom section of the plates and flows upward between them.As the feed stream moves upward, solids settle downward by descending a short distance onto the surface area provided by the plates.Solids continue to slide down the plate surfaces to a collection hopper.

Features

The lamella clarifier can be used as a supporting system equipment for water treatment processes such as air flotation and elevating methods, and can treat the following kinds of sewage. 1. The removal rate of waste water, copper, iron, zinc and nickel containing a variety of metal products in the electric water can be over 93%, and the discharge standard can be reached after treatment in the inclined tube inclined plate sedimentation tank 2. The turbidity of coal mines and wastewater can be increased from 600-1600 mg/liter to 5 mg/liter. 3. The chromaticity removal rate of printing and dyeing, bleaching and dyeing and other industrial wastewater is 70-90%, and the COD removal rate is 50-70%. 4. The removal rate of COD can reach 60-80% in wastewater from leather, food and other industries, and the removal rate of impurity solids is more than 95%. 5. The COD removal rate of chemical wastewater is 60-70%, the chromaticity removal rate is 60-90%, and the suspended solids can meet the discharge standard.
