Sewage treatment equipment includes: domestic sewage treatment equipment, integrated sewage treatment equipment, medical wastewater treatment equipment, etc.

sewage treatment (waste water treatment): the process of purifying sewage to meet the water quality requirements for draining a water body or reusing it. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering and other fields, and it has also entered the daily life of ordinary people more and more.

1. Grille: The main function of the grille is to intercept the suspended solids in the sewage, so as to reduce the treatment load of the subsequent water treatment process and protect the subsequent equipment. There are many kinds of grids: arm type, high chain type, rope type, rotary type and so on.

2. Air flotation equipment: The main function is to introduce tiny bubbles into sewage to remove tiny impurities in water. Air flotation can be used in places where precipitation method is not applicable to separate suspended solids with specific gravity close to water and difficult to precipitate, such as oil, fiber, algae and so on.

classification: electrolytic air flotation equipment, air dispersion air flotation equipment, dissolved air vacuum air flotation equipment, pressurized dissolved air flotation equipment, etc.

3. Aerator: micro-bubbles are injected into sewage through air dispersion impeller, and under the action of coagulants and flocculants, they form suspended flocs with impurities in sewage and float up to form scum.

4. integrated sewage treatment equipment: it includes a primary sedimentation tank, I and II contact oxidation tanks, a secondary sedimentation tank and a sludge tank. This is the core of sewage treatment equipment.

5. dosing device: it is mainly composed of solution tank, metering pump, filter, safety valve, check valve, pressure gauge, buffer tank, liquid level gauge, control cabinet and so on, which are installed on a base.

6. Sludge centrifuge: It is composed of rotating drum, screw conveyor, differential, main bearing, underframe, liquid-solid phase collection chamber, upper cover, motor transmission device, frequency converter and other components. Solid-liquid separation is achieved by using the speed difference.
