Abstract
The invention discloses a running method of a micro-aeration enhanced ecological floating bed for treating common heavy metal in wastewater. The method comprises the following steps: constructing a complete micro-aeration enhanced ecological floating bed device according to the actual use conditions of the micro-aeration enhanced ecological floating bed, and laying an annular micro-aeration pipeline at the bottom of the device; mounting an aeration machine with adjustable aeration quantity capable of being controlled to be 0-20 L/min; connecting the aeration machine, an air flow meter and the micro-aeration pipeline by hoses in sequence; adjusting the ventilation capacity of the aeration machine, immersing the micro-aeration pipeline in a wastewater body to be treated, controlling the reading number of the air flow meter to be 7.5 L/min to 10 L/min, and continuously aerating for 24 hours. According to the aeration scheme, the heavy metal pollution control effect of the micro-aeration enhanced ecological floating bed is greatly improved, the aeration quantity is controlled by an air compressor and the air flow meter, the operation is relatively easy and convenient, the running process is relatively stable, the energy loss due to overlarge aeration quantity is avoided, and the effect of energy conservation is achieved.
Description
Technical field
The invention belongs to heavy metal pollution regulation field, particularly relate to a kind of operation method based on the biological floating bed middle common heavy metal of disposing of sewage of micro-aeration reinforcing.
Background technology
The pollution of heavy metal to water body is tending towards serious, and it administers just extremely urgent.Not only Treatment process difficulty is higher for traditional improvement heavy metal contaminants method, and complex process, spends huge in governance process, and it is difficult to the Heavy Metal Pollution Control being applied to big area natural water.In recent years, biological floating bed technology is that green reparation of main body realization has good development in pollutant control field with plant, it utilizes plant absorption, enrichment and assimilation etc. to carry out hazardous contaminant in processing environment, can well process the various natural waters being subject to heavy metal contamination.Biological floating bed in ecological reestablishment is comparatively classical one, and it utilizes the absorption and sorption of plant, retains the Degradation with microorganism, effectively can administer the water body such as river, lake, reservoir of heavy metal contamination.Compared with traditional comparatively common heavy metal contaminants administering method, belong to the biological floating bed of ecological reestablishment has the advantages such as controlling input cost is lower, operating process simple, manage comparatively for convenience and process heavy metal contaminants is effective, treatment cycle is fast in heavy metal contaminants improvement.Therefore, utilize biological floating bed technology to administer to reach heavy metal-polluted water, thus the green improvement realizing natural water there is very high theoretical investigation to be worth and good actual application prospect.
Summary of the invention
The object of the present invention is to provide a kind of operation method based on the biological floating bed middle common heavy metal of disposing of sewage of micro-aeration reinforcing, be intended to improve biological floating bed heavy metal contamination decontamination effect improving, avoid the energy loss brought because aeration rate is excessive.
The present invention is achieved in that and a kind ofly comprises based on the biological floating bed operation method of disposing of sewage middle common heavy metal of micro-aeration reinforcing:
According to the practical situation of the biological floating bed use of micro-aeration reinforcing, build complete micro-aeration reinforcing ecological floating bed device, lay micro-aerated conduit of annular in bottom of device;
An aeration rate is installed and can be controlled in 0-20L/min, and the aerator of aeration rate size can be regulated;
Successively aerator, air flowmeter and micro-aerated conduit are coupled together by flexible pipe;
During micro-aeration reinforcing ecological floating bed device commencement of commercial operation, regulate the size of aerator air flow, when micro-aerated conduit is immersed in treatment sewage water body, the reading of air flowmeter is controlled at 7.5L/min-10L/min;
The continual aeration of aerator 24h, its aeration control is at 7.5L/min-10L/min.
effect gathers
Aeration schemes of the present invention, the effect of the biological floating bed heavy metal Pollution abatement of micro-aeration reinforcing is impelled greatly to improve, air compressor machine and air flowmeter combination is utilized to control aeration rate, operationally comparatively easy, and run comparatively stable, and avoid the energy loss brought because aeration rate is excessive, serve energy-conservation effect to a certain extent.
Accompanying drawing explanation
Fig. 1 is a kind of operation method schema based on the biological floating bed middle common heavy metal of disposing of sewage of micro-aeration reinforcing that the embodiment of the present invention provides.

S102: install an aeration rate and can be controlled in 0-20L/min, and the aerator of aeration rate size can be regulated;
S103: successively aerator, air flowmeter and micro-aerated conduit are coupled together by flexible pipe;
S104: during micro-aeration reinforcing ecological floating bed device commencement of commercial operation, regulates the size of aerator air flow, when micro-aerated conduit is immersed in treatment sewage water body, controls at 7.5L/min-10L/min by the reading of air flowmeter;
S105: aerator 24h continual aeration, its aeration control is at 7.5L/min-10L/min.
The embodiment of the present invention in disposing of sewage in heavy metal contaminants static experiment by the uninterrupted aeration of 24h, aeration rate is set to 7.5L/min, through the commencement of commercial operation of month, by carrying out tracking monitor to the heavy metal copper be subject to processing in water body in operational process, the removal rate of its final heavy metal copper reaches 91.24%.
Aeration schemes of the present invention, the effect of the biological floating bed heavy metal Pollution abatement of micro-aeration reinforcing is impelled greatly to improve, air compressor machine and air flowmeter combination is utilized to control aeration rate, operationally comparatively easy, and run comparatively stable, and avoid the energy loss brought because aeration rate is excessive, serve energy-conservation effect to a certain extent.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that performing creative labour can make still within protection scope of the present invention.
