Description
Technical field
The present invention relates to a kind of sewage-treating agent, in particular, it is related to a kind of biochemical system that improves to go ammonia nitrogen ability
Water treatment agent.
Background technology
Ammonia nitrogen in waste water is the important substance of body eutrophication and environmental pollution, and unprocessed or treatment is incomplete
Any discharge of nitrogen-containing pollutant can cause the amount reproduction of algae and other microorganisms in water；And ammonia nitrogen can cause drinking water
Peculiar smell, increases waterworks operating load；Increase the chlorine consumption in water disinfection and industrial cycle sterilisation process；Industry should
In, there is corrosivity to some metals, particularly copper；During reusing sewage, ammonia nitrogen can promote aqueduct and use in recycled water
The breeding of microorganism in wetting system, forms biofouling, blocks pipeline and water equipment, and influence heat exchange efficiency.
Water treatment agent common at present mainly includes inorganic flocculating agent and the major class of organic polymer coargulator two.It is wherein every kind of
Chemical products all has stronger specific aim, and failure, and useization are easy for when other chemical substances for having complexity are run into
After learning product, chemical residue can be left in water, side effect is easily brought to water body or even new pollution is caused.Therefore have
The water treatment agent of Biodegradable and security turns into the focus of research.
Most of organic matter and small part inorganic matter in waste water can be used by microorganism as nutriment, make
Microorganism obtains the energy or the new cell of synthesis for needing, the material referred to as substrate that these can be utilized by microorganism.If
Substrate in sewage is degradable, illustrates that the sewage can carry out harmless treatment using biological method.Biological method is by net
Changing principle can be divided into biomembrance process and activated sludge process, and due to activated sludge process research fully, operational management is convenient, financial cost
Suitably, thus in municipal sewage treatment generally it is combined with activated sludge process using Physical.This use activated sludge process
Process the feasibility of sewage, the biodegradability of abbreviation sewage.
To adding strong oxidizer to make the organic matter open loop chain rupture with macromolecular chain in waste water in waste water, will divide greatly
Sub- organic matter is converted into small organic molecule, and the degraded that small organic molecule is more beneficial for microorganism is utilized, to microbial degradation
Play the effect of key, the effective biochemical ability for improving waste water.It is residual in water and most strong oxidizers are used as chemical products
Stay and side effect easily is brought to water body.
The content of the invention
The water treatment agent that biochemical system goes ammonia nitrogen ability is improved it is an object of the invention to provide a kind of, it utilizes biological bacteria
Plant and the harmful substances such as the ammonia nitrogen in waste water are decomposed, to improve the biochemical ability of waste water.
To achieve the above object, the invention provides following technical scheme：
It is a kind of to improve the water treatment agent that biochemical system goes ammonia nitrogen ability, including following components represented with weight portion：
The nutriment includes vitamin, amino acid, sucrose, whey.
By above-mentioned technical proposal, microorganism with the organic substance of sewage as food, while to the pollutant in water body
Degraded, when the organic substance of itself is not enough in sewage, nutriment continues as microorganism and subsists as food, enters
One step promotes the growth of microorganism, improves the clean-up effect of water body, and after pollutant is purified, these microbes are with dirt
Contaminate the reduction of thing and nutriment and reduce until extinction, is converted into harmless carbohydrate, it is not easy to water body is produced secondary
Effect, reduces the situation that secondary pollution occurs and occurs；And using the combination of biology enzyme and microorganism, enzyme be by plant, animal,
The protein that bacterium, fungi and all life entities are produced and depended on for existence naturally, it is to promote chemical reaction without changing itself
Catalyst, biology enzyme by by larger molecular organicses in sewage and inorganic materialization it is small into convenient microbe absorb small molecule thing
Matter, substantially increases purification efficiency.
Preferably, the nutriment also includes sodium chloride.The microorganism include Halophiles, allotrophic nitrobacteria,
Denitrifying bacteria.
By above-mentioned technical proposal, Halophiles still has activity higher thin so as to make up heterotrophic nitrification under high salt concn
Bacterium and denitrifying bacteria active relatively low defect under high salt concn, and sodium chloride is added in nutriment for Halophiles is provided
The environment of activity is improved, while making allotrophic nitrobacteria and denitrifying bacteria that first there is relatively low activity, Halophiles is first played
Effect, Halophiles is by long-chain organic pollutant degradation for biodegradability is higher and the easy short chain small molecule being absorbed by the micro-organisms
Material, while the phagocytosis by Halophiles to short chain small-molecule substance and ammonia nitrogen, to organic pollution and ammonia in sewage
Nitrogen plays catharsis；After Halophiles plays a role, allotrophic nitrobacteria and denitrifying bacteria continue to play a role, and absorb thermophilic
The short chain small-molecule substance that salt bacterium is degraded out, and nitrification and denitrification effect is carried out to the ammonia nitrogen in water body, reduce ammonia nitrogen dense
Degree, accelerates purification efficiency and extends the clarification time, further improves the biodegradability of the pollutant in water body.
Preferably, described filler includes sludge.The filler of going back includes diatomite and nano titanium oxide.
In above-mentioned technical proposal, sludge, diatomite and nano titanium oxide be with larger specific surface area it is non-from
Subbase material, the skin effect of nano titanium oxide is conducive to making biology enzyme and microbial profile uniform, and is the life of microorganism
It is long that more sufficient carrier space is provided.Diatomite has loose structure and can be used as nano titanium oxide and the load of microorganism
Body, nano-titanium dioxide stability is high, and nontoxic pollution-free is not easy to produce secondary pollution to water body, and it is under light illumination
Easily produce with strong oxidation Superoxide anion free radical, hydroxyl radical free radical, super oxygen hydroxyl radical free radical, can by formaldehyde, benzene,
The majority harmful organic substance such as toluene, dimethylbenzene, ammonia resolves into the small-molecule substance of short chain or even resolves into harmless water and dioxy
Change carbon, the metabolism of biology enzyme and microorganism can be accelerated, improve the efficiency for increasing biodegradability.
Preferably, the biology enzyme includes protease, amylase, cellulase, lipase.
It is an advantage of the invention that：
1st, microbes are reduced up to withering away with the reduction of pollutant and nutriment, are converted into harmless carbohydrate,
It is not easy to produce side effect to water body, reduces the situation that secondary pollution occurs and occur；
2nd, the combination of biology enzyme, microorganism and the nutriment for enhancing metabolism, greatly improves and harmful substance is divided
Solution efficiency, extends the resolving time, is conducive to improving the biodegradability of pollutant；
3rd, the combination of biology enzyme, microorganism and the nutriment for enhancing metabolism, reduces microorganism and life condition is wanted
Ask, and use Halophiles, enhancing can also play a role to the adaptability of varying environment in more varying environments.
