Description
Technical field
The invention belongs to the technical field of sewage dephosphorization, more particularly to a kind of activated sludge pre-treatment medicaments and its preparation side
Method and methods for using them.
Background technology
In view of traditional biological dephosphorization technique is vulnerable to the influence of the factors such as environmental condition, operating condition so that dephosphorization system opens
Dynamic and recovery is produced compared with the problems such as slow, dephosphorization efficiency is unstable, therefore efficient polyP bacteria is isolated in screening, utilizes its enhanced sewage
The biological phosphate-eliminating of sludge, will be a key content of future studies.
The municipal sludge produced in sewage disposal process is mainly made of solid residue and water, including urban life and industry
Solid-state that sewage produces in processing procedure, semi-solid waste.Phosphorus in sludge comes from sewage, and the phosphorus in water body has two sides
Face approach:Natural action and artificial action, are mainly reflected in the following aspects:(1)By daily life, as cleaning product,
The higher waste material of the phosphorus contents such as excreta, sanitary sewage is discharged into water, and water body is caused greatly to pollute;Life at present
The discharge of sewage has surmounted industrial wastewater and has become the maximum pollution sources of body eutrophication;(2)Agriculture chemical it is a large amount of
Use, excessive phosphorus enters the surface water with rainwash or oozes under continuing and severely impacted water quality, not using partly causing
Body eutrophication;(3)All containing the material such as phosphate in the industrial wastewater that the industries such as papermaking, chemical industry, pharmacy produce, due to except
Phosphorus technology is not perfect enough, most of industrial wastewater and it is untreated or processing it is insufficient be just directly discharged into water body,
Substantial amounts of phosphorus is caused to enter water body and cause body eutrophication.Phosphorus is primarily present form in sewage to be included:Orthophosphates, gather
Three kinds of forms of phosphate and organophosphor.Quadrafos and organophosphor account for 70% of total phosphorus or so in sanitary sewage, wherein about 10% is left
The right side exists in solid form.
For the dephosphorization requirement of water body, common method includes chemical dephosphorization and biological phosphate-eliminating.Chemical dephosphorization refers to add
Some chemical agents, make the dissolved phosphorus in water body be converted into insoluble state, and then sedimentation removes.Chemical dephosphorization cost compared with
Height, and secondary pollution is be easy to cause, unsuitable long-time service.Biological phosphate-eliminating is primarily referred to as removing using microorganism excessive in water body
Phosphorus.The phosphorus in water body is removed using microbial method at home and abroad to have been carried out, this has absolutely proved that microorganism has the energy of dephosphorization
Power, such as pseudomonas(Pseudomonas)Deng.In soil chemistry insoluble phosphorus is dissolved using soil phosphate solubilizing microorganism VA mycorhiza
Hydrochlorate is built up fertility, and phosphorus that plant is difficult to absorb is converted into the absorbable form utilized, is based on microorganism pair
The effect of phosphorus.
Existing invention will modified water hyacinth air bag as one of flocculation sediment medicine component, inspired by this, we are by water calabash
Lu Xinxian blades produce the peculiar substrate of microbiological culture media as aerobic/anaerobic fermentation substrate, using water hyacinth separation of solid and liquid --
Extruding juice, extruding slag separate anaerobic fermentation, and polyP bacteria performance is lifted with the specificity of substrate in culture environment.
Water hyacinth fresh grass contains nitrogen 0.24%, phosphoric acid 0.07%, potassium oxide 0.11%, thick protein 1.2%, crude fat 0.2%,
Crude fibre 1.1%, nitrogen-free extracts 2.3%, ash content 1.3%, moisture accounts for 93.90%.In addition to as pannage and making compost, because of it
It is sensitive to arsenic, it is alternatively arranged as the indicator plant of monitoring arsenic in water body pollution level.It may be used as purifying domestic sewage and industry
Waste water purposes, but plant residue must be properly settled and rotted caused recontamination.
Water hyacinth well developed root system, absorbability is strong, can be enriched with nutrient in water.The biodegradable of water hyacinth root is low, is detesting
During aerobe fermentation, either SCOD or VFA, the concentration in water hyacinth root zymotic fluid are far below water hyacinth stem and leaf,
And the degradation rate of cellulose, hemicellulose also not as good as stem, leaf 50%.Analysis shows water hyacinth root content of lignin is excessive can
Can be the principal element for causing water hyacinth root biodegradable performance difference, this can be used as aeration sludge dilution to use.
Sodium acetate is the optimum carbon source in biological phosphate-eliminating.But it is reported that when sodium acetate or glucose are carbon source, all once cause
The collapse of EBPR systems.Have been reported that display, sodium acetate is carbon source, and when C/P ratios are 30, phosphorus release rate is the 2~4.6 of other situations
Times, and phosphorus amount/release phosphorus amount is taken the photograph as 1.58, higher than other C/P ratios, for denitrification dephosphorization rate up to 89%, denitrification denitrogenation rate is up to 98%;
When C/P ratios are less than 40, anoxic section denitrification rate is roughly the same, and C/P is than smaller, and denitrifying phosphorus uptake speed is bigger, explanation
Residual COD is more few during anoxic more is beneficial to dephosphorization;C/P ratios are more than 40, and anoxic section is released phosphorus, suction phosphorus and simple denitrification and is carried out at the same time,
Cause phosphor-removing effect unstable.
In recent years, the method for culturing sludge is replaced progressively as one of technology of sewage disposal using strain is added.South
Capital University Environment institute ox build it is quick have studied a kind of culture acclimation method of denitrogenation bacillus, it is dirty by soil, bottom mud in lake, anaerobism
