1, centrifuge: centrifuge is mainly used for the suspension of solid particles and liquid separation; or emulsion of two different densities, and immiscible liquid separation; can also be used to exclude the liquid in the wet solids, such as washing machine drying wet clothes;
Special ultra-speed tubular separator can be separated from different densities of gas mixtures; the use of different densities or sizes of solid Particles in the liquid settling speed of different characteristics, some sedimentation centrifuges can also be solid particles according to the density or size of the classification.
2, sludge dewatering machine: sludge dewatering machine is characterized by automatic control of operation, continuous production, stepless speed regulation, applicable to a variety of sludge, suitable for water supply and drainage, papermaking, foundry, leather, textile, chemical industry, food and other industries in the sludge dewatering.
3, aeration machine: aeration machine is through the diffuser impeller, the "micro-bubbles" injected directly into the untreated sewage, in the coagulant and flocculant *** with the action of the suspended solids under the occurrence of physical flocculation and chemical flocculation, resulting in the formation of large flocs of suspended solids in the bubbles under the action of the group's buoyancy! "Under the floating action of air bubbles, the floc floats up to the liquid surface to form scum, which can be separated from the water by scraper; there is no need to clean up the nozzle, and no blockage will occur.
4, microfilter: microfilter is a rotating drum screen filtration device. Treated wastewater into the drum along the axial direction, radial radial outflow through the screen, water impurities (fine suspended solids, fibers, pulp, etc.) that is retained in the drum on the inner surface of the screen. When the impurities retained in the screen is brought to the upper part of the drum, the pressure flushing water backwash to the slag discharge tank out.
5, air flotation machine: air flotation machine is a kind of removal of various industrial and municipal sewage in the suspended solids, oil and grease and a variety of colloidal substances in the equipment. This equipment is widely used in oil refining, chemical industry, brewing, slaughtering, electroplating, printing and dyeing and other industrial wastewater and municipal sewage treatment.
Note: The main features of the small sewage treatment equipment are the use of advanced technology, high degree of automation, easy to operate, simple management and long service life. Short residence time, only 3-5 minutes, high efficiency. The use of "zero speed", forced water distribution, in and out of the water are static, due to the floc in the water to minimize the disturbance, scum instantaneous removal, and therefore more stable.
Expanded Information:
Small sewage treatment equipment, the use of precautions:
1, according to the buried sewage treatment equipment installation plan and foundation plan, prepare the foundation to install the size of the floor plan size shall prevail, do a good job of the concrete sub-base, the foundation must be level, and should be in the concrete foundation poured after the end of the maintenance period before the installation, such as the equipment is installed in the ground below the ground, the foundation away from the ground the relative elevation of the size according to the plan shall prevail, at the same time Excavation width around, the length must be more than 500mm away from the foundation edge line, in order to pipe installation.
2, pipeline installation and connection should be considered in the equipment in place, the equipment must be in place according to the instructions of the weight of the equipment, with the size of the crane tonnage, the order of installation according to the site against the map in place, the location of the cylinder, the direction can not be put wrong, each other must be correctly spaced.
3, according to the installation plan, connecting pipeline, equipment in place after connecting the pipeline with rubber gasket fastening, so that the connection does not leak.
4, buried sewage treatment equipment after the installation of equipment and foundation floor must be connected and fixed, absolutely ensure that the equipment does not make the flow of floating, at the same time must be injected into the equipment, full of sewage must be more than 70% to prevent the equipment floating. At the same time, check the pipeline has no leakage. Water test each pipe junction must not leakage, at the same time, the equipment is not subject to ground water rise, and make the equipment dislocation and tilt.
