hat are the common aquaculture sewage treatment equipment

Sewage refers to water that is polluted to a certain extent in domestic and production. Water that has lost its original function is referred to as sewage. It is mainly domestic water, which contains more organic matter and is easy to handle. Do you know what aquaculture sewage treatment equipment is? Let us show you around.

Aquaculture sewage treatment equipment mainly includes the following categories:
1. Air flotation machine
The air flotation machine is a machine that uses small air bubbles or tiny air bubbles to create impurities on the surface of the medium. The air flotation device can be used for some fine particles whose specific gravity is close to that of water, and its own weight is difficult to sink or float. air float

2. Aerator
The aerator (aeration head) injects "micro-bubbles" directly into the raw sewage through an air dispersion impeller. Under the combined action of coagulants and flocculants, the suspended solids will undergo physical and chemical flocculation to form larger suspended solids flocs. Under the floating action of the bubble group, the "floc" floats on the surface of the liquid to form scum, and the scum is separated from the water by the slag scraper; there is no need to clean the nozzle and no blockage will occur. The aerator (aeration head) consists of a submersible pump, a jet, a diffuser, a suction pipe and a hose.

3. Microfilter
Microfilter is a kind of drum filter. It is a purification device that uses 80~200 mesh/square inch microporous screen fixed on the drum filter equipment to achieve solid-liquid separation by intercepting solid particles in aquaculture water. The micro filter occupies a small area, has a large production capacity (250-36000m3/D), and is easy to operate and manage. It has been successfully used in water supply and wastewater treatment.

4. Centrifuge Machine
Centrifugation is to use the strong centrifugal force generated by the high-speed rotation of the centrifuge rotor to accelerate the sedimentation speed of particles in the liquid, and to separate substances with different sedimentation coefficients and buoyancy densities in the sample. Therefore, it is necessary to use a centrifuge to generate a strong centrifugal force to force these particles to overcome diffusion and create a settling motion. Centrifuges are mainly used to separate solid particles and liquids in suspension, or to separate two liquids with different densities and insoluble in emulsion.

5. Sludge Dewatering Machine
Sludge is an inevitable product of sewage treatment in sewage treatment plants and sewage stations. There are three types of sludge in sewage treatment plants: physicochemical sludge, biochemical sludge and physicochemical biochemical mixed sludge. At present, the commonly used types of sludge dewatering machines in my country are: centrifugal type, filter belt type, spiral ring type and plate and frame type. The sludge dewatering machine has the characteristics of automatic control operation, continuous production and stepless speed regulation. Suitable for all kinds of sludge. It is suitable for sludge dewatering in water supply and drainage, papermaking, casting, leather, textile, chemical, food and other industries.

What equipment does the sewage treatment plant have?
The main function of aquaculture sewage treatment equipment is to effectively treat domestic sewage and similar industrial organic waste water, and prevent sewage and pollutants from directly flowing into the water area. This is of great significance to improving the ecological environment, enhancing the quality of the city and promoting economic development.

Aquaculture sewage treatment equipment usually refers to the mechanical equipment in the sewage treatment system, including: spiral pile dehydrator, air flotation machine, aerator, microfilter, centrifuge, grille decontamination machine, oil-water separator, filter press , Sludge scraper, sludge suction machine, decanter, sludge dewatering machine, submersible mixer, screw conveyor, sludge pump, etc.
