Description
Technical field
The present invention relates to water-treatment technology field, especially a kind of low pollution river water cleaning device.
Background technique
The main task of China's river improvement at present includes improving city city appearance and environmental quality, making city spy
Color waterfront space and the economic development etc. for driving city.Thus the renovation of China's urban river at this stage is mainly around improvement
Reservoir storage etc. expansion in urban river water quality and waterfront space environment and increase river.Domestic some scholars have done more
Research, lichee lake in Shenzhen's is handled by ecological gravel bed, but it is unobvious to the removal effect of total nitrogen, be only capable of reaching 2%；
Wuhan City zoo waste water is handled by biofilter, it is preferable to TSS removal effect, but be affected by temperature larger；Pass through oxidation
The pool-float stone bed wet land system handles Dianchi Lake Basin sewage, and denitrification effect is weaker, and water outlet can be used as general recycle-water and use.
The main problem of low pollution river water is that the nitrogen and phosphorus content of water is exceeded.
Current denitrogenation technology mainly has physical method, chemical method and bioanalysis.Physical method mainly has membrane separation process, main
The problem is that since membrane separation process is to the removal non-selectivity of nitrate, at the same have also been removed the overwhelming majority in water it is inorganic from
Son, causes process cost increase, and membrane separation process effect in application to engineering practice is poor.Chemical method is mainly using reduction
The catalytic reduction method of agent, the problem of being primarily present are that chemical method is stringent to catalytic condition requirement, and is also easy to produce metallics
Secondary pollution, operating cost are excessively high.Anti-nitration reaction in bioanalysis needs carbon source as electron donor, and therefore, selection is suitable for
Additional carbon it is most important in biological denitrification process.
Be primarily present form of the phosphorus in water body is particulate form and solubilised state.Wherein the phosphorus of particulate form passes through sedimentation, filtering
The methods of be easier to remove；The phosphorus of solubilised state includes orthophosphates, Quadrafos and organic phosphorus, Quadrafos and organic phosphorus in acidity
Under the conditions of can be hydrolyzed to orthophosphates.Therefore during dephosphorization, the main removal considered to orthophosphates.Currently used for removal
The method of low phosphorus mainly has bioanalysis, physical method and chemical method etc. in water body.Biological phosphate-eliminating technology mainly has artificial swamp
With A/O treatment process etc..Artificial swamp is easily blocked vulnerable to climatic effect, matrix in application process, to low phosphorus pollution
The clean-up effect of natural water is unobvious, and A/O treatment process is flexible and stability is poor, easily generation sludge bulking.Absorption method master
If achieving the purpose that separate phosphorus from waste water by the physical-chemical reaction between adsorbent and phosphor in sewage.It inhales
Common adsorbent adsorption capacity in dephosphorization is limited in attached method, easy saturation, needs to frequently replace.Chemical rule often use aluminium salt and
The metal salts such as molysite carry out flocculation dephosphorization, easily cause secondary pollution.Therefore in order to remove the low phosphorus in natural water, it is badly in need of
Find that a kind of dephosphorization ability is strong, cost is relatively low and nontoxic dephosphorization material.
