Description
Technical field
The present invention relates to industry and useless (dirt) water treating equipment of life, particularly the treatment facility of oil-containing/emulsifying waste water that enterprise production process such as iron and steel, machinery, food and drink are produced.
Background technology
Air flotation technology has been widely used in trade effluent such as oil, chemical industry, process hides, weaving, printing and dyeing, iron and steel, rubber, food, light industry and city domestic sewage and to water treatment.The effect of air flotation technology in water and wastewater treatment can be divided into following a few class: (1) is used for oil, chemical industry and machinofacture oil-containing, contains the fat wastewater treatment as individual event main body treatment technology; (2) as preconditioning technique, remove hardly degraded organic substance, improve wastewater biodegradability; (3) be used for the reuse treatment process of sewage second-level treat effluent as the advanced treatment technology; (4) replace sludge thickener as concentration technique.
The mode that produces according to micro bubble can be divided into: gas distribution air supporting, air-dissolving air-float and electrolysis (flocculation) air supporting, wherein partial reflux formula pressure air-dissolving air-float is the most frequently used technology of water treatment, but because its equipment is many, maintenance cost is high, energy consumption is high, the noise of air compressor machine is big etc. shortcoming is replaced by other air floatation form just gradually.Electrolytic process is better than other bubble production methods, and its bubble is tiny, all can detect and be easy to control rapidly to processing efficiency height, air supporting time and other operational conditions of waste water, reliable and safety in operation, and floor space is little and have a special advantages.At present in the research at home and abroad, utilize the floating technical finesse oily(waste)water of electricity, dyeing waste water, heavy metal wastewater thereby, leather waste water etc. all to obtain satisfied effect, adding under the situation of suitable flocculation agent, the clearance of oils, chemical oxygen demand (COD), turbidity even phosphorus is all being reached more than 90%.
The major cause that restricts electric float glass process widespread use is that current consumption is higher, and electrode materials also short need of burn into life-span is often changed, thereby has increased working cost, and the easy passivation of anode also is one of its defective in addition.Mainly have the following disadvantages in the prior art: electrode block surface deposition fouling easily when (1) contains the high waste water of greasy filth or salinity in processing; (2) electrode block terminal stud and pond body are fixed together, because the easy loss of electrode block, disassembly procedure complexity when changing electrode block at set intervals need just can be finished by certain instrument; (3) pulsed current produces by conventional trigger formula rly., weares and teares easily in the contact, and the power-supply system working life is not long, and owing to open and close frequently, has noise.
