Description
The application is application number 201510049264.0,31 days January 2015 applying date, " a kind of sewage is net for denomination of invention
The divisional application of change material and preparation method thereof, purposes and the method for sewage disposal ".
Technical field
The present invention relates to sewage purification field, and in particular to a kind of to carry out denitrogenation using sulphur/lime stone autotrophic denitrification
One kind sustained release sewage purification material.
Background technology
The pollution problem of nitrate has been to be concerned by more and more people in water, and it is too high particularly to quote nitrate concentration in water
The carcinogen that water body produces nitrosamines can be induced, causes neonate to be susceptible to suffer from high ferro methemoglobinemia disease.The pollution master of nitrate
Will the discharge from fertilizer and pesticide excessive use, industrial and life contaminated water in agricultural production.
At present, economic denitrogenation technology is bio-denitrification technology, is divided into heterotrophic denitrification technology and autotrophic denitrification technology.
Because heterotrophic denitrification technology needs to put into organic matter, cost is high and also causes the secondary pollution of organic matter.Autotrophic denitrification skill
Art is with DIC, such as CO2Or HCO3 -For carbon source, mainly with H2, sulphion, thiosulfate, NH4 -Equipotential nitrate reducing
Electron donor completes the metabolism of microorganism, is nitrogen by nitrate reduction.The advantages of autotrophic denitrification technology, has：With inorganic
Thing is electron donor, no organic substance residues；2) without additional organic carbon source, so as to reduce operation and cost of investment；3) autotrophy
Type bacterium growth rate is low, reduces the risk of the biological pollution of water outlet.
In existing autotrophic denitrification technology sulphur/lime ground mass purifying agent for polluted water in use, the H of generation+、SO4 2-,
The calcium sulfate of generation microsolubility is reacted with lime stone, internal layer lime stone is hindered and further neutralizes newly-generated acid, so as to suppress
Denitrifying smoothly positive the problem of carrying out.Meanwhile generally use is cumbersome using the method repeatedly to feed, operation；Using
The once method of enough additions, cause sulphur source and acid-base value and each micro- release heterogeneity, to autotrophy bacteria microorganism
It is unfavorable to grow.
The content of the invention
It is an object of the invention to provide a kind of sewage purification material that can continue to use, and specifically provides a kind of operation letter
Single, economical and practical sewage purification material, is used as autotrophy source, there is provided slowly releasing trace element, utilize biology using lower-cost sulphur
Autotrophic denitrification carries out denitrogenation processing to sewage, the nitrate nitrogen that can effectively go in water removal.
Technical scheme provided by the invention is a kind of sewage purification material, and the material includes sulphur source, lime stone, polyphosphoric acids
The cotton fiber of salt, sylvite, magnesia, cupric oxide, zinc oxide, molybdate, borate and regain more than 7%；Described
Sulphur source is thiosulfate；Described sylvite is the one or more in potassium phosphate, potassium chloride, potassium sulfate, potassium carbonate.
Described sulphur source is the sulphur of elemental sulfur or water-soluble reduction-state；The sulphur of water-soluble reduction-state is sulfide or thio sulphur
Hydrochlorate, such as the one or more in vulcanized sodium, potassium sulfide, zinc sulphide, manganese sulfide, iron sulfide, ferrous sulfide；
Described sylvite is the one or more in potassium phosphate, potassium chloride, potassium sulfate, potassium carbonate.
Described fiber is the fiber that regain is 8%~16%, such as cotton fiber, silk fiber.
The mass ratio of each composition in above-mentioned sustained release sewage purification material, with element sulphur (sulphur in sulfate radical)：Lime stone：
P elements：Potassium element：Magnesium elements：Copper：Zn-ef ficiency：Molybdenum element：The mass ratio of the material of boron element is (2.3-2.7) *
106：(1-1.6)*106：(0.1-0.3)：(0.3-0.6)：(0.3-0.5)：(0.1-0.2)：(0.1-0.2)：(0.06-0.1)；
The dosage of fiber is the 0.6-2.1% of above-mentioned raw materials gross mass.
The present invention also provides a kind of preparation method of above-mentioned sewage purification material, it is characterised in that concretely comprises the following steps, will match somebody with somebody
Sulphur source, lime stone in side, polyphosphate, sylvite, magnesia, cupric oxide, zinc oxide, molybdate, borate crush respectively
10-40 mesh sieves are crossed, high regain fiber cutting is the short fibre of 0.5-3cm length；Then in formula ratio ratio, each material is weighed；Will
Sulphur source is first well mixed with lime stone, then other raw materials by addition to fiber and water are well mixed, and then equivalent, which is progressively increased, has mixed
Even sulphur source, lime stone and fiber, mixed process add the water equivalent to raw material gross mass 3-5%；After all raw materials mix
It is compressing, it is drying to obtain sewage purification material.Pressure when compressing is preferably 15-20MPa；It is pressed into block or ball-type
Thing.Block or ball-type thing size can be adjusted according to being actually needed, what the moon was sustained, volume 100-150cm3, Zhou Huan
Release, volume 6-15cm3, the 0.5-3cm of sustained release on the three3。
The present invention also provides purposes of the above-mentioned sewage purification material in nitric wastewater is handled.
The present invention also provides method of the above-mentioned sewage purification material in processing nitric wastewater, such as rural sewage, industrial wastewater
And sanitary sewage, it is specific as follows：
1) sewage in cesspool is adjusted into pH to 6.5-7.0；Autotrophy bacterial content is adjusted to 17-50mg COD/L；Measure
NO3 -- N content；
2) by NO in the sulphur source in sustained release sewage purification material and sewage3 -The ratio between-N amount of material is 0.5-2.6 ratio
Example, input sustained release sewage purification material；Stirring daily twice, monitors nitrate, when concentration drops to desired value (such as 5mg/l
Or standard value) below, complete denitrification for Removing Nitrogen.
Compared with prior art, excellent characteristics of the invention are shown：
1) convenient material drawing.Each raw material is cheap and easy to get, and cost is cheap.
2) feed intake conveniently.Process cycle, such as three days, one week, the cycle of one month can be selected according to sewage property, selects phase
Answer slow-release material, it is not necessary to feed intake daily, greatly save labour cost.
3) after feeding intake, each nutriment and trace element, can steadily discharge needed for autotrophic bacterium, keep convenient concentration, avoid
What is often occurred in the prior art feeds intake initial stage, and each component concentration reaches peak value, is then gradually reduced, and is not suitable for the growth of microorganism
And work, What is more, because of the improper death that can cause microorganism of concentration, does not play a part of not only handling sewage, on the contrary
Pollution is also aggravated.
4) present invention can play skeletal support, adhesive effect, also because it contains using the technology for mixing high regain fiber
There is more hydroxyl, bootable moisture is slowly entered inside sustained release, so as to slowly cause the disintegration of sustained release, is avoided because of sulfuric acid
The generation of calcium or other water not capacitive material is covered in sewage purification material surface so as to hinder the release of sulphur source, lime stone to ask
Topic, ensure denitrifying be smoothed out.
5) sewage purification material provided by the invention, operating cost expense is relatively low, simple to operate, is easy to manage, raw material damage
Consumption is few, is a kind of economic, simple sewage purification material.
