The special ultra-high speed tubular separator can also separate gas mixtures with different densities; Some settling centrifuges can also classify solid particles according to their density or particle size, and the settling speed of solid particles with different density or particle size in liquid is different.
2. Sludge dewatering machine: Sludge dewatering machine has the characteristics of automatic control operation, continuous production and stepless speed regulation, and is suitable for sludge dewatering in water supply and drainage, papermaking, casting, leather, textile, chemical industry, food and other industries.
3. Aerator: The aerator directly injects "micro bubbles" into the untreated sewage through the diffuser impeller. Under the joint action of coagulant and flocculant, suspended solids undergo physical flocculation and chemical flocculation to form large suspended solid flocs, which float to the liquid surface to form scum under the floating action of bubbles, and are separated from water by a slag scraper; There is no need to clean the nozzle, and no blockage will occur.
4. Microfiltration machine: Microfiltration machine is a roller screen filtration device. The treated wastewater enters the drum along the axial direction and flows out through the screen along the radial direction, and impurities (fine suspended solids, fibers, paper pulp, etc. ) is trapped on the inner surface of the screen on the drum. When the impurities trapped on the filter screen are carried to the upper part by the roller, the pressure washing water is backwashed into the slag discharge tank to flow out.
5. Air flotation machine: Air flotation machine is a kind of equipment to remove suspended matter, grease and colloid from various industrial and urban sewage. The equipment is widely used in the treatment of industrial wastewater and urban sewage such as oil refining, chemical industry, brewing, slaughtering, electroplating, printing and dyeing.
Note: The main features of small sewage treatment equipment are advanced technology, high degree of automation, convenient operation, simple management and long service life. Short stay time, only 3-5 minutes, high efficiency. When "zero speed" is used, forced water distribution and water inlet and outlet are static. Because the disturbance to the floc in water is minimized and the scum is instantly removed, the stability is higher.
Extended data:
Matters needing attention in the use of small sewage treatment equipment:
1. According to the installation drawing and foundation drawing of buried sewage treatment equipment, prepare the foundation and concrete floor according to the size of the installation drawing. The foundation must be horizontal and can only be installed after the pouring and curing period of the concrete foundation is over. If the equipment is installed below the terrace, the relative elevation of the foundation from the terrace shall be subject to the drawing size, and the width and length of the surrounding excavation must be more than 500mm away from the foundation sideline, so as to install the pipeline.
2. Pipeline installation and connection should be considered when the equipment is in place. When the equipment is in place, it must conform to the equipment weight and crane tonnage. According to the field comparison diagram, the installation sequence should be in place. The position and direction of the cylinder must not be misplaced, and the distance between them must be correct.
3. Connect the pipes according to the installation drawing. After the equipment is in place, fix the connecting pipe with rubber pad to prevent water leakage at the joint.
4. After the installation of buried sewage treatment equipment, the equipment and the foundation slab must be connected and fixed to absolutely ensure that the equipment does not flow or float. At the same time, sewage must be injected into the equipment, and the fullness must reach more than 70% to prevent the equipment from floating. At the same time, check whether there is any leakage in each pipeline. There shall be no leakage at the intersection of the water testing pipeline, and the equipment shall not be affected by the rise of surface water, so that the equipment is staggered and tilted.
