Abstract
The invention discloses a method for wastewater recovery two stage precipitation reaction, and the method is characterized in that the method comprises the following steps: 1) wastewater is collected by a pipeline and enters a wastewater treatment station zone, incoming water is pre-precipitated in a primary precipitation tank, pre-precipitated outgoing water enters a water collection regulation pond; and regulated water is treated in anaerobic bacteria and aerated by a fan, and enters a secondary-stage precipitation tank; 2) the secondary-stage precipitation tank comprises a dosing device and an ammonia-nitrogen reactor; and after ammonia-nitrogen reaction, a flocculant and a coagulant aid are added for fully reacting with the wastewater; and 3) reacted wastewater is deslagged byairfioatation slag removal equipment, and the airfioatation slag removal equipment includes an airfioatation tank, a dissolved gas tank, a gas dissolved water pump and an air compressor. According to the method, harmful substances in the wastewater are removed, useful components are recovered, the purpose of recycling of raw materials containing nitrogen is achieved, and the method is quick and efficient, and does not need human intervention.
Description
Technical field
The present invention relates to a kind of sewage disposal technology is and in particular to a kind of sewage reclaims the method that two-stage precipitation reacts.
Background technology
Near the cultivation factory of poultry or livestock, substantial amounts of aquaculture wastewater can be collected, contain a large amount of in aquaculture wastewater
Bacterium, but, after being recycled, be also good waste material.
How fast and effectively recycling to be carried out to breeding wastewater, become the direction of prior art development.
Content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides nitrogenous former in a kind of recovery sewage
The method of material, by steps such as precipitation, recovery, effectively collects the benefit materials in waste liquid, solves the deficiencies in the prior art.
Technical scheme：For achieving the above object, the technical solution used in the present invention is：It is anti-that a kind of sewage reclaims two-stage precipitation
The method answered is it is characterised in that the method comprises the following steps：
1) waste water enters Sewage Disposal area after piping collection, carries out preliminary sedimentation in preliminary sedimentation tank to water, after preliminary sedimentation
Water outlet enter and catchment regulating reservoir；Enter anaerobic bacteria after regulation to process, enter second-level settling pond after blower fan aeration；
2) described second-level settling pond includes chemicals dosing plant and ammonia nitrogen reaction unit；Ammonia nitrogen reaction after, add flocculant and
Flocculation aid, is sufficiently reacted with waste water；
3) reacted waste water is carried out except Slag treatment by air supporting slag removal equipment, and described air supporting slagging-off includes flotation tank, molten
Gas tank, dissolved air water pump and air compressor machine.
Further, described precipitation tank depth is 1.5 meters.
Further, described automatic medicine adding apparatus include sensor, when 0.5 meter of water level arrival in regulating reservoir is detected are,
Start dosing.
Further, described step 1) in, the sediment after preliminary sedimentation is processed is reclaimed.
Beneficial effect：The method of nitrogen-containing material in a kind of recovery sewage that the present invention provides, by precipitation, slagging-off, reclaims
Deng, after except the harmful substance in decontaminated water, useful component is reclaimed, reach reclaim nitrogen-containing material purpose, quickly have
Effect, without manual intervention.
Specific embodiment
Below the present invention is further described.
A kind of sewage reclaims the method for two-stage precipitation reaction it is characterised in that the method comprises the following steps：
1) waste water enters Sewage Disposal area after piping collection, carries out preliminary sedimentation in preliminary sedimentation tank to water, after preliminary sedimentation
Water outlet enter and catchment regulating reservoir；Enter anaerobic bacteria after regulation to process, enter second-level settling pond after blower fan aeration；
2) described second-level settling pond includes chemicals dosing plant and ammonia nitrogen reaction unit；Ammonia nitrogen reaction after, add flocculant and
Flocculation aid, is sufficiently reacted with waste water；
3) reacted waste water is carried out except Slag treatment by air supporting slag removal equipment, and described air supporting slagging-off includes flotation tank, molten
Gas tank, dissolved air water pump and air compressor machine.
Further, described precipitation tank depth is 1.5 meters.
Further, described automatic medicine adding apparatus include sensor, when 0.5 meter of water level arrival in regulating reservoir is detected are,
Start dosing.
Further, described step 1) in, the sediment after preliminary sedimentation is processed is reclaimed.
The method of nitrogen-containing material in a kind of recovery sewage that the present invention provides, by precipitation, slagging-off, recovery etc., is removing
After harmful substance in sewage, useful component is reclaimed, reach the purpose reclaiming nitrogen-containing material, quickly effectively, need not be artificial
Intervene.The above be only the preferred embodiment of the present invention it should be pointed out that：Those skilled in the art are come
Say, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should be regarded as
Protection scope of the present invention.
