Description
Technical field
The invention belongs to technical field of waste water processing, specifically is a kind of waste water of livestock poultry method for innocent treatment, correspondingly also proposes the method that isolate utilizes again after the wastewater treatment.
Background technology
Along with people's is known the life condition of fowl poultry kind animal, life habit etc.; Also be in order to satisfy different taste demands simultaneously; Increasing fowl poultry kind animal has greatly been satisfied people's demand gradually by stable breeding, but also our living environment is caused certain negative impact.Because the waste water that stable breeding caused of fowl poultry kind animal contains large amount of organic; Its pollution load is higher, as if directly entering or get into rivers and lakes with rain drop erosion, the dissolved oxygen in the meeting mass consumption water body; Make the water body blackening smelly; And nutrition such as its a large amount of N that contain, P can cause body eutrophication, make the responsive hydrobiont of Organic pollutants deadly gradually, and severe patient causes river forfeiture functions of use.Waste water of livestock poultry permeates the ground for a long time, and nitric nitrogen or nitrite nitrogen concentration in the underground water are increased, and the underground water dissolved oxygen content reduces; Toxic ingredient increases; Cause water quality deterioration, even lose its functions of use, the water quality of periphery tap water of crisis simultaneously and domestic water.High-concentration waste water also causes the soil pores to be stopped up, cause that soil is ventilative, water-permeable descends and harden, salinization, seriously reduce soil quality, even the injury farm crop, cause the underproduction and death.
At present, utilize the chemical pollutant in the ultrasonic degradation water, especially the organic pollutant of difficult degradation is the novel environmental improvement technology that development in recent years is got up.This technological operation mild condition, degradation speed are fast, applied widely, can unite use separately or with other water technology, are a kind of technology of very promising and application prospect.UW is not direct acoustic wave action to organic degraded, but with liquid in produce collapsing to go out substantial connection being arranged of cavitation bubble.The UW of sufficient intensity is when the liquid, and in the sound wave negative pressure semi-period, the micro-bubble (cavitation nucleus) that is present in the liquid can be grown up rapidly, the sound wave malleation that comes one after the other mutually in; Bubble adiabatic compression and collapsing again goes out, and is collapsing the moment of going out, the bubble formation hot localised points; Its temperature is up to 5000K, the big 500atm of pressure, and this focus cools off thereupon then; Rate of cooling reaches 109K/s, and in liquid with powerful shockwave, this has just created an extreme physical environment for organic degraded.From present result of study analysis, though ultrasonic technology has carried out Study on degradation to tens of kinds of organism, be mostly the single component simulation, and contain multiple pollutent in the actual waste water of livestock poultry, adopt the ultrasonic degradation technique effect undesirable merely.
Centrifugal separation technique is the differences of utilizing between the different substances such as density, with the Physical Separation Technology that centrifuge field is separated and extracted, is widely used in fields such as biology, medical science, agronomy, chemistry, chemical industry.To most of bio-fermented liquid finely ground particle substances, centrifugal efficient and simple method often.Though spinning ability separate small particles material can not reach the ideal separating effect to water miscible material.
Sorbent material is from gas or liquid, to adsorb the wherein solid matter of some composition effectively.Sorbent material generally has following characteristics: big specific area, suitable pore structure and surface tissue; Adsorbate there is the intensive adsorptive power; Generally not with adsorbate and medium generation chemical reaction, easily manufactured, easily regeneration; Excellent mechanical intensity etc. is arranged, but use cost is higher, processing efficiency is low, and use range is less.
According to literature search, do not see the bibliographical information that relevant waste water of livestock poultry harmless treatment is arranged.
Summary of the invention
The purpose of this invention is to provide a kind of waste water of livestock poultry method for innocent treatment, adopt solid-liquid separation, the isolating system for handling of organic substance, can reduce the organic matter of waste water of livestock poultry, the content of nutritive ingredient effectively; Solve the waste water of livestock poultry environmental pollution problem; Technology is simple, and is easy to operate, and efficient is high; For the waste water of livestock poultry harmless treatment provides an effective way, has realistic meaning.

See that from test-results field of vegetables saline-alkali soil is used a certain amount of soil improvement agent and not only had and more significantly change the alkali effect, and can obviously improve the structure of salt affected soil, reduces salt content.Amount of application is big more, and action time is long more, and soil water stability crumb structure content is big more, and the pH of soil is low more, and the range of decrease of soil salt content also increases.
Though the present invention has done detailed description with general explanation and specific embodiments to technical scheme, on basis of the present invention, can to some modifications of do or improvement, this will be apparent to those skilled in the art.Therefore, these modifications or the improvement on the basis of not departing from spirit of the present invention, made all belong to the scope that requirement of the present invention is protected.
