a、分离地表水中细小悬浮物，藻类等微聚体。 b、回收工业废水中有用物质，如造纸废水中纸浆等。 c、代替二沉池分离和浓缩水中污泥等悬浮物。
1, the application range of air floatation machine:
A, separation of fine suspended particles in surface water, algae and other micropolymers. B, recycling industrial waste water useful material, such as pulp and paper pulp and so on. C, seperating and concentrating sludge such as sludge in water instead of two sink pool.
2, the aerator (aerator) is composed of five parts, a submersible pump, a jet, a diffuser, a suction pipe and a hose.
3, the microfilter has a small area, large production capacity (250-36000m3/d), convenient operation and management, and has been successfully applied to the treatment of water and wastewater.
4, centrifuge is mainly used for the solid particles and liquid suspension separation or emulsion of two different densities, but also separation of immiscible liquids.
5, the characteristics of sludge dewatering machine are automatic control operation, continuous production, stepless speed regulation, and suitable for many kinds of sludge. It is suitable for sludge dewatering in many industries such as water supply and drainage, paper making, casting, leather, textile, chemical industry, food and so on.
The degree of wastewater treatment is pided into monocular and primary treatment, two stage treatment and three stage treatment. The solid state physics and usage of suspended solids are mainly used in primary treated sewage. After one treatment, the BOD removal rate of wastewater is only 20%, which is still discharged. The main task of the 2 stage treatment two stage treatment is to remove colloidal state and dissolved organic matter in sewage, and the BOD removal rate is 80% to 90%. Usually two levels of sewage treatment can meet the emission standards, regular activated sludge process and biofilm treatment for three grade treatment purposes. There are some examples of special pollutants, such as fluoride, phosphorus removal and other deep treatment of conventional chemical sewage engineering port type spraying.
1, strengthen the transformation of the existing primary treatment process, according to the actual situation, make full use of existing treatment facilities, application of grass existing hospital in the septic tank, the contact structure and operation mode of transformation, when necessary, adding a part of the facility effect, in order to improve the treatment of hospital sewage treatment discharge standards.
