Wastewater Treatment Rotary Disc Filter

1. Input the sludge stock liquid into the sludge stabilization tank in the spiral solid liquid separator, inject the reagent into the sludge stabilization tank, and stir it fully with the sludge by the mixer.

2. The conditioned sludge in the sludge stabilization tank is pumped by the built-in sludge pump to the "V "shaped meter, and the measured sludge enters the flocculation reactor.

3. After the sludge enters the flocculation reactor, the second agent is injected, and it is fully mixed and reacted to form a large alum, and then sent into the sludge filtration body. After the sludge is fed into the filter body, it first enters the gravity thickening part. 

4. In the thickening part, a large amount of solid matter is quickly separated from water, and then the sludge is pushed to the dewatering part. In the dehydrating section, use motion. The relative movement of the disc and the continuous enhancement of the pressure in the filter chamber result in efficient dehydration and dry cake discharge out of the machine. 

5. Under the action of high internal pressure in the filter body, the outer surface of the filter cartridge sometimes has a small amount of SS along with the filtrate overflow, so the upper part of the filter body is provided with a spray nozzle, and a small amount of spray water is used to keep it clean. Return the sewage after spraying 

6. Into the sludge stabilization tank. Such design, construction and operation can reduce costs.

FAQ：

1. Structural composition and working principle of a stepped grid cleaning machine

The JT stepped grid cleaning machine is a new type of grid cleaning machine.

The JT type stepped grid cleaning machine is mainly composed of a frame, a driving mechanism, an eccentric rotating mechanism, fixed grid bars, mobile grid bars, etc.

The eccentric rotating mechanism of the grid cleaning machine rotates under the drive of the motor reducer, driving the moving grid to generate reciprocating step motion relative to the fixed grid, so that the impurities in the water are alternately carried by the fixed grid and the moving grid, like going up stairs, gradually moving up to the upper discharge port of the machine frame and automatically unloading.

2. Characteristics and advantages of wire rope grille cleaning machine

The GS type steel wire rope grille cleaning machine is mainly used to intercept and salvage large floating objects in the water, to ensure the normal and safe operation of the water pump's subsequent work.

The main characteristics of the wire rope traction grille cleaning machine are:

① The grille structure is simple, easy to maintain, and has a large amount of salvaged debris;

② Has strong closing rake force

③ The steel wire rope traction grille cleaning machine has strong corrosion resistance and is flexible and convenient for maintenance and repair;

④ Equipped with a comprehensive and reliable mechanical and electrical dual protection system, it operates safely and facilitates automatic operation control.

The company also produces a large number of customized crushing grids and grid cleaning machines.

Product introduction

Rotary fiber cloth filter filter system is a mature, stable and reliable water treatment filtration technology, which can efficiently remove the total suspended matter in water, combined with the addition of chemicals, can remove phosphorus and chroma, etc., and is widely used in: deep treatment of wastewater cooling circulating water treatment, water reuse, surface water purification and upgrading of urban sewage treatment plants and industrial wastewater treatment. Compared with the traditional sand filter, the rotary fiber filter system has obvious advantages such as low investment, low operation and low footprint.

How it works:

After raw water enters the filter, under the action of gravity pressure difference, it enters the filter disc through the microporous filter cloth fixed on the hollow rotating shaft and the solid suspended matter is trapped on the outside of the filter cloth. The filtrate is collected through the filter disc to the hollow rotating shaft and flows into the outlet tank, and the filter tank is discharged through the outlet weir plate. With the accumulation of sludge on the filter cloth, the filtration resistance of the filter cloth increases, and the liquid level in the tank gradually rises. When the liquid level rises to the set value, the PLG starts the suction pump and the transmission device at the same time, so that the filter disc rotates, and the cleaning device fixed on the outside of the filter cloth rubs against the surface of the filter cloth, scraping and absorbing the sludge on the surface of the filter cloth. Finish cleaning the filter cloth. The sludge pipe is set at the bottom of the pool, and the sludge settling at the bottom of the pool is discharged automatically by the PLC through the time setting.
