Description
Technical field
The present invention relates to river sewage process fields, and in particular to a kind of black foul sewage water treatment technology in river.
Background technique
With the rapid development of the national economy, environmental pollution is got worse, and especially river water body pollutes, in addition to nitrogen phosphorus etc.
Except the pollution of eutrophy ingredient, house refuse, such as: plastics, kitchen garbage seriously affect the self-purification capacity in river, it is long this with
It is past, lead to problems such as river water body black and it is smelly, at this time, it may be necessary to river water body carry out purified treatment, however, river water body
Purified treatment and its by-product resource efficiently recycle be current urgent need to resolve technical problem.Therefore, each ambit is special
Family is jointly to how the technology that efficient process river water body and its by-product resource recycle is studied.Due to common river
Water body processing technique there are processing costs high, processing heavy workload and by-product is more and the defects such as added value is low.Therefore, urban river water
Body needs to improve in terms of high-efficient purification and by-product resource recycling.
Summary of the invention
The purpose of the present invention is to provide a kind of black foul sewage water treatment technology in river, the black foul sewage water treatment technology in the river is adopted
With river sewage treatment process and river sludge treatment process, this technique have odor removal efficient is high, water body recovery technology removal rate is high,
The product of the advantages such as sludge economic benefit height, production has excellent bigger serface.To achieve the goals above, of the invention
Technical solution is as follows:
A kind of black foul sewage water treatment technology in river, including river sewage treatment process and river sludge treatment process, in which:
(1) river sewage treatment process:
Flocculant is prepared by following steps:
Be 20:36~45:11~21:0.06~0.5:3~8:2~6 flocculant of polymeric aluminium chloride by mass parts ratio,
Polyacrylamide flocculant, acrylamide, ammonium persulfate, water and ferroso-ferric oxide are added in reaction kettle, and mixing speed is
90r/min, reaction temperature are 50~83 DEG C of 0.5~6h of reaction, and product is spray-dried through 105~140 DEG C；
High activity active carbon is prepared by following steps:
It is 32:5~9:67~95:55~62:22~29:3~7:2~5 active carbon, four oxidations three by mass parts ratio
Iron, formic acid, butyl titanate, tetraethyl orthosilicate, nickel acetate and copper acetate are added in autoclave, mixing speed 45r/
Min, reaction temperature are 65~91 DEG C of 0.2~1.5h of reaction, product through 135~162 DEG C of 3~7h of hydro-thermal reaction, product is washed,
It is dry；
0.2%~3% flocculant is added into per cubic meter of water into river sewage, after mixing, is stood, Xiang He
Every cubic metre of 0.5%~6% high activity active carbon of addition in road sewage is stood, with 1000~3000W LED after mixing
UV illumination 3~30min of river water, clears up water-outlet body for river sludge；
(2) river sludge treatment process:
It is 27:52~69:8~17:9~16 that mass parts ratio is added in the river sludge cleaned out in by step (1):
The pecan shell powder of 12~19:22~39, river sludge powder, soybean peel powder, corn stalk powder, polyacrylamide water-absorbing resin and
Urea is added in high-speed mixer, and mixing velocity is 300~600r/min, and mixing temperature is 30 DEG C of mixing 25min, product
Through -5~-30 DEG C of freeze-dryings, 100~125 DEG C, be heat-treated 0.5~3.5h under the conditions of 0.7~3MPa, product through 150 DEG C of heat at
Manage 0.5h, 200 DEG C of heat treatment 0.5h, 300 DEG C of thermal bake-out 1h, 400 DEG C of thermal bake-out 1h, 500 DEG C of thermal bake-out 2h, 600 DEG C of thermal bake-outs
2h, 800 DEG C of thermal bake-out 3h, obtains porous carrier.
Solid suspension and impurity are more in river water body, firstly, can be by river water body surface rubbish by modes such as scraper plates
Rubbish is such as: plastic bottle, gloves, foam removal, secondly, quickly removed suspended matter in river water body by flocculant, furthermore, lead to
Excessively high active charcoal purifies adsorbent in water body, finally, river sludge is carried out recycling recycling.
Preferably, the pecan shell powder, river sludge powder, soybean peel powder, corn stalk powder, polyacrylamide water suction
The mass parts ratio of resin and urea is 27:63:12:13:15:34.
The beneficial effects of the present invention are:
1. reacting in flocculant by acrylamide polymerization and introducing ferroso-ferric oxide, the density of flocculant can be improved, improved
The flocculation rate of flocculant, flocculant can be obviously shortened water body recovery technology flocculation time and flocculation efficiency；
2. photochemical catalyst is introduced in high activity active carbon, it is using the suction-operated of active carbon that foul smell absorption in river is simultaneously rich
Collect in high activity active carbon, the photochemical catalyst in high activity active carbon is recycled to carry out photocatalytic degradation, solution to black odour
The certainly smelly problem of water body；Ferroso-ferric oxide can improve the fall rate of high activity active carbon；The high activity active carbon of preparation can be bright
The aobvious foul smell content for improving water body；
3. pecan shell powder, river sludge powder, soybean peel powder, corn stalk powder and polyacrylamide water-absorbing resin have compared with
High water absorbing properties can absorb the moisture in sludge, prevent the loss of moisture, freeze-dried, be able to maintain the original moisture of material
The pore structure occupied, after high-temperature process, pecan shell powder, river sludge powder, soybean peel powder, corn stalk powder, polypropylene
The pore creating material of amide water-absorbing resin and urea as material, can be obviously improved the porosity of sludge.
