The operation principle of pretreatment unit 1 is as follows in this product：

Being cooperated between dissolving 1-3 and several Gas dissolving pipes 8 makes to produce substantial amounts of micro air bubble in treating column 1-1, It is set to be adhered to waste water Midst density with water close pollutant solid or liquid particle, polluting thing global density and being less than water State, and it is risen to the water surface by buoyancy, form the form of scum silica frost, the floating of the water surface is scraped off by Slag Scraping Device 20 Slag, oil removing, suspension or other polluters are gone to reach the purpose to purify water.

The technological process of pretreatment unit 1 is that effluent part enters dissolving 1-3 through reflux pump 1-2 pressurization Posterior circles, is being added Press under air condition, air supersaturation dissolving, then mixed at treating column 1-1 with water inlet, it is oversaturated because pressure reduces Air is discharged, and forms micro-bubble, is attached to oil slick rapidly, on suspension, and it is promoted to the table of pretreatment unit Face, so as to form the sump oil, the sludge floating layer that are easy to remove, scraped by the Slag Scraping Device 20 in treating column 1-1 to sump oil case 21 In, so as to outer row.Heavier solid material and heavy oil are deposited in the bottom of pond of sludge-tank 22, are removed through outer venting.

Its inner chamber is divided into by the tank body 2-2-1 in this product in filtering tank 2-2 by diaphragm plate, in lower three chambers, on Intracavitary is outlet system, is provided with water distribution system and filtrate anti-losing system, so takes full advantage of filter space, while can have Effect prevents filtrate from losing；Lumen is mainly filtration system, and isometrical filtrate is distributed in filtration system, and filtrate loads height and reached More than 2 meters, cavity of resorption is water inlet system, while is furnished with the equal distribution system of source of the gas.During work, sewage is entered by epicoele, is filtered through lumen, Discharged by cavity of resorption；During backwash, sewage is entered by cavity of resorption, through lumen, is discharged by epicoele.

Purifier is controlled by pressure difference, timing automatic backwash, when accumulation of impurities is being filtered in purifier Material surface causes inlet outlet pressure differential to increase to setting value, or when timer reaches setting time, electric operated control box sends signal, enters Wetting system stops, and backwashing equipment starts, and special backwash water distribution design, it is anti-that impulse jet type air water is produced when can make recoil Developing result, the cleaning of filtrate can be effectively carried out, it is after purifier inlet outlet pressure differential returns to normal value or fixed When device setting time terminate, whole backwash process structure, system recover normal operation, in whole backwash process, filtrate It is not lost in, backwash water consumption is few, realizes serialization, automated production.

This product effectively realizes the effect of combined water and air backwash by backwashing pump 2-5 setting, and each micro-filtration layer is micro- Expansion, pollutant is sheared by current, air shearing, the comprehensive function collided between rubbing action and filtering material particle, it is and single Water backwashing mode is compared, and due to adding shear action of the air to filtering material particle, rubbing action, while the addition of air is strong The collision between current shearing, rubbing action and filtering material particle is changed, so combined water and air backwash, can recoil in less water Wash intensity and be issued to more preferable backwash effect.
