Problems solved by technology

[0006] However, the existing sewage treatment technology in our country leads the sewage to the sump, adjusts the pH at the end of the sump, uses the first-level dissolved air pump to lift it to the first-level pressure dissolved air tank, and sucks in air and coagulation decolorizer at the same time. The first-level saturated air-dissolved water in the first-level pressure dissolved air tank is suddenly released to the first-level air flotation tank to form the first-level treated water; the first-level treated water overflows into the buffer tank, and then the second-level dissolved air water pump is used to control the pH. Lift to the secondary pressure dissolving tank, suck in air and coagulation decolorizer at the same time, release the secondary saturated dissolved air water in the secondary pressure dissolving tank suddenly to the secondary air flotation tank to form secondary treated water and self-overflow to The sedimentation tank is discharged after sedimentation; the floating mud in the first and second air flotation tanks enters the floating mud tank, press-filtered into a filter cake, and the filtrate is returned to the collection tank. The CODcr, decolorization rate, SS, BOD5 of industrial sewage treated by this technology The removal rates are 80-90%, 95%, more than 90%, and 75-80%. Although they meet the national emission standards, there is still a certain gap with the international advanced national emission standards. The CODcr, decolorization rate, SS, BOD5 The removal rate is still low, and it still has a great impact on the ecological environment and natural water systems, thus endangering people's lives

Embodiment 1

[0023] Example 1 The sewage enters the bottom of the 108-cylinder body from the 103-water inlet through the 102-inlet water distributor, the sewage rises slowly, and overflows the 116-filter support net to filter out impurities in the sewage, and the sewage rises further. Rise to the 106-support seat, place a large amount of active iron on the 106-support seat, the active iron reacts with the heavy metal ions in the sewage, and the 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↓ (the reaction process of other heavy metals is the same), the heavy metals attached to the surface of the active iron are washed by the 104-backwash water distributor, and settle to the bottom of the 108-cylinder, and the water that meets the discharge standard for the removal of heavy metals is sent by the 109-tube head The 111-water outlet at the upper end is discharged.

Embodiment 2

[0024] Example 2 After the sewage treatment is completed, water is diverted from the 112-washing water inlet at the upper end of the 109-tube head into the 108-cylinder, and the water passes through the active iron area to remove the dirt on the surface of the active iron, and is discharged from the 114-rinsing water outlet.

Embodiment 3

[0025] Example 3 When it is necessary to add or replace active iron, enter the 108-cylinder body from the 110-upper manhole at the upper end of the 109-cylinder head to replace the active iron.

Abstract

The invention provides a ferric carbon tower for sewage treatment. The ferric carbon tower consists of a base, an inflow distributor, a water inlet, a kickback water distributor, a flange barrier tube, a supporting seat, a fixing platform, a cylinder body, a cylinder head, an upper manhole, a water outlet, a wash water guiding port, a lower manhole, a wash water outlet, a supporting platform and a filtration supporting mesh, wherein the base is connected with the lower end of the cylinder body for supporting; the lower end of the inside of the cylinder body comprises the inflow distributor connected with the water inlet; the other end of the inflow distributor is supported by the supporting platform; the inflow distributor is provided with the filtration supporting mesh; one end of the bottom of the cylinder body comprises the wash water outlet; the position 1000MM far away from the base comprises the lower manhole; the middle of the inside of the cylindrical body comprises the supporting seat on which the kickback water distributor is supported; and one end of the damage end cylindrical head of the cylindrical body comprises the upper manhole, the top of the cylindrical body is provided with the water outlet, and the other side of the cylindrical body comprises the wash water guiding port. The ferric carbon tower has the beneficial effects that chemical oxygen demand (CODcr), decoloration and biochemical oxygen demand 5 (BOD5)-removing rate of sewage in sewage treatment are improved to above 90.8%.

Description

【Technical field】 [0001] The invention relates to the technical field of a sewage treatment device, in particular to the technical field of an iron-carbon tower for sewage treatment. 【Background technique】 [0002] As we all know, although 70.8% of the earth is covered by water, fresh water resources are extremely limited. What humans can really use are rivers, lakes and a part of groundwater, which only account for 0.26% of the total water on the earth, and the distribution is uneven. [0003] After the 1950s, the global population grew rapidly and industry developed rapidly. The situation of global water resources is rapidly deteriorating, and the "water crisis" is becoming more and more serious. On the one hand, the human demand for water resources is expanding at an alarming rate; on the other hand, the increasingly serious water pollution has eroded a large amount of water resources available for consumption. [0004] About 200 tons of garbage is poured into rivers, l...
