Abstract
The present invention relates to a kind of method of disposing sludge, and in particular to a kind of method of the sludge that disposal aluminum oxide factory production waste water is produced.Technical scheme is as follows:A kind of method for disposing the sludge that aluminum oxide factory production waste water is produced, the sludge for first producing production wastewater treatment system, being put into sludge concentration tank carries out concentration;Then, the supernatant that concentration is produced is back to production wastewater treatment system, the sludge after concentration is forced through into sludge pipe through sludge pump is delivered to red mud for alumina plant disposal system;Finally, the sludge for being postponed by place is delivered to red mud dump together with red mud and stores up.The method of the sludge that the disposal aluminum oxide factory production waste water that the present invention is provided is produced, the sludge that waste water generation will be produced is mixed with red mud, red mud dump is sent to store up, it is to avoid production water treatment station individually carry out environmental pollution produced by Treatment of Sludge, take up an area it is big, invest the technical barriers such as many, maintenance management inconvenience.
Description
Technical field
The present invention relates to a kind of method of disposing sludge, and in particular to one kind disposal alumina producer life
The method for producing the sludge that waste water is produced.
Background technology
Alumina producer production needs a large amount of steam and recirculated cooling water, therefore aluminium manufacturer to set and provide for oneself
Power plant and circulation.Power plant for self-supply and circulation, natural water are typically difficult to
Meet technique productions requirement, it is general that production wastewater treatment station is set.Production wastewater treatment station sludge
Treatment is general to use sludge after concentration basin carries out gravity concentration, with dewatering machine such as belt pressure
Filter, chamber-type press filter, centrifugal dehydrator etc. carry out mechanical dehydration, filter cake automobile after dehydration
Outer to be transported to stockyard storage, it is larger to there is plant equipment investment in the method, safeguard and operating cost compared with
High the shortcomings of.
In alumina producer production technology, the waste residue that bauxite is produced after the operations such as dissolution, separation
(red mud), through sedimentation, separates and washing etc. is after operation, or directly with being pumped into red mud
Field is stored up, or is stored up with red mud dump is then sent through after filter filtering.1 ton of aluminum oxide of production is produced
Raw about 1.2 tons of red muds, the sludge quantity that production waste water is produced only has 1.5% of red mud amount or so.
The content of the invention
The present invention provides a kind of method for disposing the sludge that aluminum oxide factory production waste water is produced, by life
Produce the sludge that waste water produces to be mixed with red mud, be sent to red mud dump and store up, it is to avoid in life
Produce water treatment station individually carry out environmental pollution produced by Treatment of Sludge, take up an area it is big, invest it is many,
The technical barriers such as maintenance management inconvenience.
Technical scheme is as follows:
A kind of method for disposing the sludge that aluminum oxide factory production waste water is produced, will produce waste water first
The sludge that processing system is produced, being put into sludge concentration tank carries out concentration;Then, will concentrate
Process the supernatant for producing and be back to production wastewater treatment system, by the sludge warp after concentration
Sludge pump is forced through sludge pipe and is delivered to red mud for alumina plant disposal system;Finally, pass through
The sludge that place postpones is delivered to red mud dump together with red mud and stores up.
The method of the sludge that described disposal aluminum oxide factory production waste water is produced, wherein, sludge is dense
Contracting process time is 12~18h.
The method of the sludge that described disposal aluminum oxide factory production waste water is produced, wherein, at concentration
In red mud disposal system, into red- mud settlement and separation and washing room three wash sludge after reason
Mixed with red mud in waterpower mixing channel, then carried out washing and filtering.
Beneficial effects of the present invention are:Sludge after concentration, by being promoted to alumina producer
Three wash water power mixing channels of red- mud settlement and separation washing room, into red mud disposal system, finally
It is delivered to red mud dump together with red mud to store up, while being capable of opposite using utilization red mud strong basicity
Produce wastewater sludge to be nursed one's health, lift its dewatering, reduce final moisture percentage in sewage sludge, reduce
Environmental pollution;It is not required to set sludge dewatering system simultaneously, reduces investment and operating cost, tool
There are significant economic benefit and social benefit.
Brief description of the drawings
Fig. 1 is the equipment flowsheet for disposing the sludge that aluminum oxide factory production waste water is produced.
Specific embodiment
As shown in figure 1, a kind of method for disposing the sludge that aluminum oxide factory production waste water is produced, first
The sludge that first production wastewater treatment system 1 is produced, being put into sludge concentration tank 2 is carried out at concentration
Reason, sludge condensation process time is 12~18h;Then, the supernatant for concentration being produced
Production wastewater treatment system 1 is back to, the sludge after concentration is pressurizeed through sludge pump 3 logical
Cross sludge pipe and be delivered to red mud for alumina plant disposal system 4, into red- mud settlement and separation and wash
Mixed with red mud in the three wash water power mixing channels for washing workshop section, then carried out washing and filtering;Most
Eventually, the sludge postponed by place is delivered to red mud dump together with red mud and stores up.
Claims (3)
