Fertilizer, can also be used to cultivate algae.Therefore, how to realize that livestock culture dung recovery is utilized and non-secondary pollution, be mesh
Preceding problem demanding prompt solution.
Contain a large amount of loop chain organic compounds in aquaculture wastewater（High concentration COD）, nitrine class inorganic compound（Uric acid）With
Ammonia nitrogen, suspension etc., these materials either enter water body（Such as enter surface water body or the water body that permeates the ground）, or it is therein
Some substance releases enter air, and they can produce serious harm, the ecological ring of destruction to animal and plant directly or indirectly
Border.Inorganic matter is general in aquaculture wastewater exists in forms such as ammonium salts, such as NH4+, NH3, SCN-, CN-, SO42-, TP.It is organic
Thing in addition to CODcr, BOD5, SS etc., also including aliphatic compound, heterocycle compound and polycyclic aromatic hydrocarbons (PAH) etc., while also wrapping
Include petroleum-type, animals and plants oily substance.Contain substantial amounts of poisonous and harmful substance in sewage, some of which phenolic compound can make carefully
There is denaturation and precipitate in born of the same parents' protein, have direct toxic action to various cells, can also cause methemoglobinemia；Its
Middle cyanide belongs to extremely toxic substance, into after organism, can be combined with swage cytochrome oxidase high, becomes cyaniding swage high thin
Born of the same parents' chromo-oxidase, the effect for making it lose transmission oxygen causes poisoning so as to cause histanoxia；It is wherein substantial amounts of many
PAH and heterocycle compound, are much suspected of carcinogenic and mutagenic matter, wherein substantial amounts of organic matter enters water body
Afterwards, substantial amounts of dissolved oxygen in water will be also consumed, water hypoxia will be caused, aquatile will be endangered.Because sewage breaks to natural, ecological
Bad extremely serious, the threat to the mankind is huge, therefore, not only it is administered, and thoroughly to be administered, and
Prevent the transfer of pollution and produce secondary pollution, while to carry out being circulated utilization to limited water resource.Although waste water
Treatment can use burning, wet oxidation, sonolysis, ozone oxidation, liquid chlorine oxidation, Chlorine Dioxide Oxidation, ion exchange, steaming
Various physics such as stripping is removed, extraction and recovery, biological decomposition, chemistry, physicochemical or biochemical method, individually or
It is used in combination and obtains a certain degree for the treatment of.But the process of most physics and chemistry is not largely effective to wastewater treatment,
Some treatment are not thorough, and some meetings cause pollution transportation or produce secondary pollution, at method physically or chemically
Reason waste water, its operating cost is extremely high, and general enterprises are beyond affordability.Therefore, Experience in Development both domestic and external is used for reference, China starts
Greatly develop green agriculture and build ecological environmental-protection cultivation.For example, the excreta or sewage collecting of the mankind and animal are fermented
Afterwards, obtain biogas and the sewage disposal system of various energy utilization devices is set around biogas.At this stage, this sewage disposal system
System remains in the application of small-scale and small range, and most of methane-generating pit is to carry out regeneration to sewage unilaterally, is obtained
After biogas, remaining biogas slurry and biogas residue are abandoned as waste material.In addition, biogas residue and biogas slurry are often deposited on methane-generating pit bottom, biogas slurry and
Biogas residue mixes and is difficult to separate, it is necessary to artificial periodically salvage that separate after cleaning can be further with.The utilization rate of sewage
Still very low, engineering construction high cost, economic benefit is low, it is difficult to large-scale promotion.Meanwhile, the sewage after treatment is often difficult to reach
To discharge standard, severe contamination is caused.
