Description
Technical field
The present invention relates to technical field of waste water processing, more specifically, are related to a kind of ammonia nitrogen in waste water, COD, total phosphorus efficiency and go
Except agent and preparation method thereof.
Background technique
According to National Industrial discharge of wastewater primary standard, ammonia nitrogen in waste water concentration should be less than 5mg/L, cod less than 50 mg/L,
Total phosphorus is less than 0.5 mg/L；For earth's surface three classes water, three's numerical value is corresponding are as follows: 1.0 mg/L, 20 mg/L, 0.2 mg/L.Ammonia
There are many exceeded wastewater treatment methods of nitrogen, COD, total phosphorus, and in general, the exceeded wastewater treatment of ammonia nitrogen substantially has following several
Mode: the methods of break point chlorination, air stripping method, biological nitration, selective absorption are more commonly used and economical at present
Method；COD exceeded wastewater treatment has: absorption method, chemical coagulation process, electrochemical process, Ozonation, bioanalysis, light electrolysis
Deng being removing in a word or decompose organic matter in sewage；The exceeded wastewater treatment of total phosphorus has: ion-exchange, bioanalysis, suction
Attached method, membrane separating method, chemical precipitation method.
In the processing of ammonia nitrogen overstandard waste water, break point chlorination makes the ammonia in waste water by adding excess chlorine or sodium hypochlorite
It is oxidized to N2.Break point chlorination is high to the removal rate of ammonia nitrogen, the steady point for the treatment of effect, and is not influenced by water temperature, but is handling
In the process, operating cost is higher；Under alkaline condition, ammonia nitrogen is mainly with NH for air stripping method3Form exist, allow waste water and empty
Gas comes into full contact with, volatility NH in water3It will be from liquid phase to gas to transfer.It is by the PH of waste water, temperature, hydraulic loading, fouling control
The influence of the factors such as system；Biological nitration is under aerobic condition, by the effect of nitrite bacteria and nitrate bacterium, by ammonium oxidation
At nitrite nitrogen and nitrate nitrogen.The factors such as temperature, pH value, dissolved oxygen can have an impact treatment effect；Selective absorption
Method has well-regulated cellular structure and hole, is sieved, exchange adsorption, this method using in the three-dimensional space fouling of zeolite
It is affected by the pH value of solution.
In the exceeded wastewater treatment of COD, absorption method can be adsorbed by active carbon, macroreticular resin, bentonite isoreactivity
Material, particulate organic matter, coloration in adsorption treatment on sewage.It can be used as pre-treatment, reduce the COD for being easier processing；Change
The organic matter in waste water can be effectively removed by learning Coagulation Method, largely reduce the COD of waste water；Electrochemical process be it is direct or
Electrolysis is indirectly utilized, water pollutant is removed, or noxious material is become non-toxic or low-toxic substance；Ozonation
COD is reduced using the very strong oxidation disinfection ability of ozone, but ozone has toxicity when concentration is slightly higher；Bioanalysis is by microorganism
Enzyme aoxidizes or restores organic molecule, destroys its unsaturated bond and chromophoric group, to reach a kind of waste water of processing intent
Processing method；Light electrolysis handles a kind of ideal technology of high concentrated organic wastewater, also known as internal electrolysis at present.It is in no power
In the case where, 1.2V potential difference is generated using the micro-electrolysis material being filled in waste water itself, and electrolysis processing is carried out to waste water, with
Achieve the purpose that degradable organic pollutant, the technique for hard-degrading high concentrated waste water processing can be greatly reduced COD and
Coloration improves the biodegradability of waste water, while can have good effect to the removing of ammonia nitrogen.
In the exceeded wastewater treatment of total phosphorus, ion-exchange removes total phosphorus using strong-base anion-exchange resin；It is raw
Object method reduces phosphorus content using activated sludge or simple biological inoculum；Absorption method using porous substance as adsorbent and from
Sub- exchanger；Phosphonium ion passes through liquid film by selectively penetrating, extraction, absorption etc. in membrane separating method, into interior phase reagent into
Row chemical reaction, to reduce phosphorus content；Chemical precipitation method generates indissoluble by the phosphate added in dephosphorization agent and waste water and sinks
Starch can separate phosphorus, and the floccule body being formed simultaneously also has Adsorption effect to phosphorus.
The exceeded processing method of ammonia nitrogen, COD, total phosphorus is not quite similar in waste water, but it is same often to there is three in actual production
Shi Chaobiao or in which the exceeded situation of the two, to individually be handled, then technique formality is very cumbersome；Equipment construction is also corresponding
Huge, high construction cost；Ton cost of water treatment is expensive.And the means that can be used simultaneously are only adsorbed, but adsorb maximum problem
It is that adsorption capacity is low, regeneration trouble, and production capacity is limited, is unable to meet production needs, can only use as advanced treating.
Summary of the invention
