Description

A kind of sewage disposal iron carbon tower
[technical field]
The present invention relates to a kind of waste disposal plant technical field, be specifically related to a kind of technical field of sewage disposal iron carbon tower.
[background technology]
Though the well-known earth has 70.8% area to be covered by water, Freshwater resources are extremely limited, and the mankind really can utilize is a part in rivers and lakes and the underground water, only takes up an area of 0.26% of ball Total Water, and skewness.
After the 1950's, global population sharp increase, industrial development is rapid.The water globe resource situation worsens rapidly, and " water crisis " is on the rise.On the one hand, human demand to water resources enlarges with surprising rapidity; On the other hand, serious day by day water pollutes that nibble in a large number can be for the water resources of consumption.
The whole world has 200 tons of rubbish to pour river, lake and brook into every day approximately, and every liter of waste water can pollute 8 liters of fresh water; The river in all cities, Asia of flowing through is all contaminated; The processed food wastes in water resources basin, metal, fertilizer and the pesticide pollution of the U.S. 40%; Europe only has 5 water quality barely satisfactory in 55 rivers.In 20th century, world population has increased twice, and human water has increased by 5 times.Many in the world countries are faced with water resources crisis: 1,200,000,000 human water shortages, 3,000,000,000 people lack the water sanitary facility.
The water resources in china occupancy volume per person is few, the spatial distribution imbalance.Along with Chinese Urbanization's, industrialized acceleration, the demand gap of water resources also increases day by day.Under such background, sewage treatment industry becomes new industry, and present and tap water production, water supply, draining, middle water reuse industry are in status of equal importance.
And the existing sewage disposal technology of China draws sewage toward water collecting basin, to water collecting basin end one style joint pH, rise to the first class pressure dissolving with one-level dissolved air water pump, suck air and coacervation discoloring agent simultaneously, will be discharged into the one-level air flotation pool at the one-level saturated dissolved gas water in the first class pressure dissolving suddenly and form the one-level treating water; The one-level treating water overflows into Buffer Pool, the one-level treating water is promoted in the secondary pressure dissolving with secondary dissolved air water pump at control pH again, suck air and coacervation discoloring agent simultaneously, the secondary saturated dissolved gas water in the secondary pressure dissolving is discharged into the secondary air-floatation pond suddenly forms secondary treated wastewater and discharge from overflowing to the settling tank post precipitation; Mud scum in the I and II air flotation pool is gone into the mud scum pond, press filtration becomes filter cake, filtrate returning causes water collecting basin, the clearance of the CODcr of the industrial sewage of this technical finesse, percent of decolourization, SS, BOD5 is respectively more than 80~90%, 95%, 90%, 75-80%, though reach discharging standards but certain gap still arranged with advanced country's emission standard in the world, the clearance of its CODcr, percent of decolourization, SS, BOD5 still is on the low side, ecotope and natural stream networks are still produced considerable influence, therefore jeopardize people's life.
[summary of the invention]
For solving above deficiency, the invention provides a kind of sewage disposal iron carbon tower, this device adds activated carbon simultaneously by its rational layout, effectively remove heavy metal ion and organism in the sewage, make the clearance of COD of sewage cr after the processing, percent of decolourization, SS, BOD5 reach higher level.
A kind of sewage disposal iron carbon tower is by base, the water inlet water distributor, water-in, the recoil water distributor, flange retaining pipe, supporting seat, stationary platform, cylindrical shell, the tube head, last manhole, water outlet, wash-down water draws mouth, following manhole, flush out the mouth of a river, support platform, filtering supporting network forms, base is connected support with the cylindrical shell lower end, the inner barrel lower end comprises an inlet distribution device that is connected with water-in, the other end of inlet distribution device is supported by support platform, the inlet distribution device is equipped with one on it and filters supporting network, bottom one end of cylindrical shell comprises wash-down water outlet, cylindrical shell comprises manhole from base 1000MM place, the middle part of inner barrel includes supporting seat, support upper support the recoil water distributor is arranged, the first end of wound end tube of cylindrical shell comprises manhole on, and a water out is arranged at the top, an other side includes a wash-down water and draws mouth.
Described a kind of sewage disposal iron carbon tower is characterised in that described inlet distribution device and recoil water distributor are evenly distributed with ostium excurrens.
Described a kind of sewage disposal iron carbon tower is characterised in that described recoil water distributor is fixed on the supporting seat, can place active iron on this supporting seat.
Described a kind of sewage disposal iron carbon tower is characterised in that described cylindrical shell appearance is a guiding principle matter, and interior table is a glass reinforced plastic
On the supporting seat of cylindrical shell, put into the active iron of reaction needed by manhole, its capacity is no more than 2/3 height of cylindrical shell, after sewage enters the inlet distribution device by water-in, evenly enter container bottom, and slowly raise, and filter out impurity in the sewage through filtering supporting network, and and being positioned at active iron reaction on the supporting seat, this reaction process is: Fe+2H 2--→ Fe 3++ H 2↑ Fe 3++ 3OH ---→ Fe (OH) 3
Fe+CU 2+--→ Fe 2++ Cu ↓ Fe+Zn 2+--→ Fe 2++ Zn ↓ (other heavy metal reaction process are identical)
Ironing surface dirt of water cleaning active or reacted heavy metal that the aperture that even perforate on the recoil water distributor distributes is gone out make it be deposited to the cylindrical shell bottom.
Beneficial effect of the present invention: the present invention effectively solves COD of sewage cr, the percent of decolourization of sewage disposal in the prior art, the clearance of BOD5 is brought up to more than 90.8%.
Further understand feature of the present invention and technology contents for making, see drawings and embodiments of the present invention for details, yet appended graphic only for reference and explanation usefulness is limited the present invention.
