Description

A kind of organic waste-water treating apparatus containing ammonia and processing method
Technical field
The invention belongs to water-treatment technology field, and in particular to a kind of organic waste-water treating apparatus containing ammonia and processing method, Ammonia in waste water and organic matter are effectively removed, the processing unit and device user of reuse or qualified discharge after processing Method.
Background technology
Organic wastewater containing ammonia is widely present in the industry productions such as daily life and chemical industry, medicine, papermaking.In recent years Come, with the enhancing of country and people's environmental consciousness, processing of the country to organic polluting waters such as nitrogen, phosphorus is more paid attention to, various The denitrogenation technology of ammonia-containing water also turns into study hotspot.Ammonia-containing water denitrogenation, qualified discharge, the ammonia-containing water processing of various concentrations Different technique should be respectively adopted.
Strong ammonia wastewater should use physics, chemical method to carry out Nitrogen recovery utilization first, low in it is converted into After concentration ammonia-containing water, then using Biochemical method or deep treatment method processing.Vaporizing extract process is by the trip in waste water with steam It is changed into ammonia effusion from ammonia, i.e., in high ph-values, makes waste water and gas close contact, so as to reduce the mistake of ammonia density in waste water Journey.The motive force of mass transport process is the difference between the partial pressure of the ammonia in gas equilibrium partial pressure suitable with the concentration of ammonia in waste water.Prolong Long gas and the time of contact between water and contact tightness degree and can improve the treatment effect of ammonia nitrogen, can meet that this will with packed tower Ask.The filler of tower can increase gas and water by increasing infiltration surface area and small water droplet or generation film being formed in whole tower Between time of contact.Vaporizing extract process is to the clearance of ammonia nitrogen up to more than 97%.
Middle low concentration ammonia-containing water should be taken off according to C/N ratio ranges from traditional handicraft, biological reinforced technique or autotrophy Nitrogen technique.Traditional denitrification process is ripe based on trend, and biological reinforced technique is also substantially perfect, when condition is appropriate, can trust From.If from autotrophic denitrification technique, it must be noted that two defects of the technique：One is at this stage technology relative coarseness, It is immature, need to be further improved, the second is when total nitrogen limits strictly and influent ammonium concentration is higher, only with autotrophic denitrification Technology, it is impossible to meet the requirement of " strengthened denitrification " and " advanced nitrogen ".The technique usually requires to be combined with traditional handicraft, to protect Demonstrate,prove water quality objective.
The processing of low concentration ammonia-containing water can use traditional handicraft.Even if C/N is low, additional carbon without too many expense, And denitrification effect is reliable and stable, BAF and denitrification filter pool are preferably to select.For there is advanced nitrogen requirement When, the technique such as chemical oxidation, even counter-infiltration is also preferable option.New autotrophic denitrification technique is in low concentration field of sewage containing ammonia Research it is less, it is necessary to the work that further conducts a research.
After the adjusted pH of waste water containing organic pollution and ammonia, it is pumped into by water pump via the upper end water distributor of reactor Atomizer, while start air pump, air enters reactor, the process that ammonia declines in droplet by micro-pore aeration plate or air inlet Middle stripping removes, and porous plate can increase the residence time that droplet stripping removes ammonia, so as to increase except ammonia efficiency.Ammonia is from positioned at anti- The ammonia escape orifice on device top is answered to send next stage to handle after overflowing.Droplet drops down onto the activation oxygen catalysis oxidation pond of reactor lower end, Air is exposed into producing strong oxidizing property after the catalyst action in catalysis oxidation pond by the micro-pore aeration plate at catalysis oxidation bottom of pond end Oxygen radical, the organic pollution in oxidation removal waste water.
The processing method and technique of ammonia nitrogen waste water, Chinese patent 200810104999.9,200410064524.3, 200410034065.4,200310106515.1,03152877.5,02137109.1 carried out substantial amounts of research work, formed The a variety of processing methods such as blow-off method, biomembrance process, chemical precipitation method, membrane absorption method, break point chlorination, ion-exchange.Its In, blow-off method technique is more ripe, and efficiency high is stable, but power consumption is big.Bioanalysis requires ammonia nitrogen concentration in 400mg/L Hereinafter, there is the problem of seepage and fouling membrane of film in membrane absorption method, although chemical precipitation method technique is simple, efficiency high, throw Dosing dosage is larger, and operating cost is high, and can produce a large amount of sludge.Break point chlorination handles the effect stability of waste water, is only applicable In low concentration, accessory substance chloramines or chlorinatedorganic will also result in secondary pollution of water.Ion-exchange is applied to middle low concentration Ammonia nitrogen waste water (concentration is less than 500mg/L), for the ammonia nitrogen waste water of high concentration, can because exchanger regeneration frequently and caused by operate Difficulty, the exchanger capacity after regeneration declines, and the ammonia nitrogen in regenerated liquid still needs to handle, and causes operating cost higher.
