Integrated Skidded Equipment for Oily Sewage TreatmentI. Overview:HY-OW series oily sewage treatment equipment are a new generation of sewage treatment equipment researched and developed based on the sewage treatment equipment originally produced by Henan Dongsheng Environmental Polytron Technologies Inc. It is unanimously agreed that the technical indexes of the product reach advanced level of products of similar type in China after its putting into operation through many tests,Website:http://www.dhpetrotools.com, tests of environmental protection department and appraisal of experts.Such latest technologies as advanced jet dosing condensation method and air floatation separation method that produces air-dissolved water by high speed jetting are adopted for oily sewage treatment equipment products, and they have the following advantages compared with products of similar type:1. Chemical agent can be automatically added by controllable ratio, which overcomes the defect of dosing by experience and eliminated the old method which adds chemicals with metering pump and ensures optimum effects of flocculation, demulsification and neutralization;2. The latest technology that directly mix the air with water by high speed jetting technology to produce air-dissolved water is adopted, the air-dissolved water produced has stable quality, which greatly enhances the effect of floatation separation. In the meantime, air compressor is eliminated and water treatment cost is reduced, thus noise pollution of air compressor is avoided.3. SF efficient anti-blocking releaser is adopted, which prolongs the air floatation time, increases purification effect and relieves the burden of subsequent processes. In the meantime, the equipment shutdown caused by blocking of releaser is also eliminated;4. The technology to produce gas-dissolved water by jetting method is applied, gas dissolving column is replaced by pipeline gas dissolving system, which make the operation simpler, safer and more reliable;5. The treatment process is perfect, with the feature of one machine for multiple purposes. User can select, give up and combine the procedures as per the requirements of quality standards of recycled water;6. The design of the equipment is reasonable, with compact structure, low occupation area, low energy consumption and stable effect. They are ideal and economic industrial sewage treatment equipment.II. Working Principle and Process Flow of Oily Sewage Treatment EquipmentWorking principle:Process 1:Grille well-----Regulating reservoir-----Reaction chamber-----Coagulation sedimentation tank-----Air floatation separation tank-----Clean water reservoir-----EffluentProcess 2:Treatment efficiency1. Oil removing rate≥95%;2. COD removing rate≥70%;3. Removing rate of suspended matter≥85%.
