84. Algae eliminating machine the eliminating of the algae is by machine without the adding of medicament. The elimination ratio is 80£90%, it is easy to manage for its automatic operation. It is used in the pretreatment of algae containing water in lakes, reservoirs and the treatment of urban sewage and industrial wastewater.
85. SBR group type reactor with a active sludge method SS in the mix liquor MLSS£º4000£10000mg/1, reaction time£º4£6h, sludge index SVI£º80£150, organic loading£º3.0£5.0kgCOD/kgMLSS.d. It is used in the treatment of urban sewage and industrial wastewater.
86. Internal recycle trinomial bio-fluidized bed The output water quality meets the effluent standard after the treatment of the urban sewage. The water residence time has reduced by 50% comparing with the conventional biomethod; it can be an equipment of the pretreatment or treatment of industrial sewage. It is made of porous carrier which is wearable and with a good mechanical strength. The price performance ratio is high than the general carriers. The circulant fluidization is smoothly, and its power consumption is lower than the conventional fluidized bed and is equivalent with the biological treatment. It is used in the treatment of urban sewage and industrial wastewater.
87. Membrane bioreactor The biology in the reactor is over 10g/1, dimension loading can be enlarged widely so the reactor is a small type whose output water has a good quality and meets the standard of reclamation water. It is used in the treatment of urban sewage and the reclamation of the water.
88. Polluted drinking water treatment by photooxidation It has a good eliminating ability for the pollutants in the drinking water with a high ratio of reaction. Ti can treat a lot of polluted water. The equipment is a small type. It is used in the treatment of drinking water.
89 Equipment complex for the fertilizer making quickly by sludge Handling amount£º5£50m3 /d for (dried sludge), the water content of the grain fertilizer£¼25%£»the fertilizer can be modified according the requirement. The product can meet the hygienic evaluation standard of high temperature compost. It is adequate for the treatment and comprehensive utilization of urban sludge.
90 An integrated plant for horizontal centrifugal hydroextractor and sludge thicking machine The diameter of the drum is 450£720mm£»ribbon width ratio is L/D=3-4£»separation factor can be 3500. It is used in the treatment of urban sewage and industrial wastewater.
91 New style of ozonizer Datch index: power consumption per uint¡Ü15kWh/kgO3 when oxygen is the raw material and ¡Ü25kWh/kgO3 when air is the material. Characteristics are: the reaction for oxygen and the reaction for ozone is apart, so they can be carried out in proper conditions respectively. So the net production of the ozone is improved largely. The process need not cooling, so the power consumption has been reduced largely and the volume of the plant has been reduced. When the air is the raw material, the by-product nitric oxides can be reduced. The new technology improves the capacity usage ratio for about 2-3 times comparing with the old one, and the plant volume reduce for over a half, so the cost of the whole cost of manufacture has reduced by 30£50%. Besides, it can produce a flow which ozone content is over 10% of the flow. It is used in the water supply and treatment of the waste water.
92 SBR large scale revolving decanting instrument
One decanting instrument¡Ý1000m3/h, the water depth ¡Ý3m. It is used in the treatment of urban sewage and industrial wastewater.
93. Auto monitoring system and instrument in the urban effluent treatment plant It is made by bus DCS separating type on-site control system and PLC programmable digital controller. The ratio of parts made in China is over 60%. It is adequate for the treatment of urban wastewater.
