Description
Technical field
The present invention relates to sewage treatment fields more particularly to a kind of filtering to control sewage water treatment method.
Background technique
The method solution that many problems in terms of traditional wastewater processing can be combined with physical absorption and bio-absorbable
Certainly.The scheme of the prior art is usually big carbon content active (up to 15 mg/litres) to be added in traditional filter device, simultaneously
Two kinds of processes of biological treatment and physical treatment of generation: biodegradable pollutant is absorbed by biologic artifact, and not biology drop
The pollutant of solution is then adsorbed on charcoal.Combined process generates a kind of its treatment effect of synergism-better than individually or series connection method
Effect.The process can expeditiously remove BOD, COD and suspended solid；It can control smell and color；It removes poisonous substance and carries out
Nitrification.Charcoal is reused, and system matches a set of carbon step for regeneration, in favor of reducing cost and eliminating the processing of secondary solid substance.So
And the noise of this method filtering is larger and bad for the eradicating efficacy of organism.
Therefore, a kind of new filtering control sewage disposal system is needed in the prior art, then can be widely used in multiple
Field, and the influence of noise bring can be reduced.
Summary of the invention

Method, in the data basis that the personnel where to fish jar in house are customized detection, the organism based on fish bowl water
Percentage composition determines whether triggering water quality filter device, meanwhile, also when the personnel amount where fish jar in house is less, close
Water quality filter device is closed to avoid to noise pollution is caused in relatively quiet house, to weaken water quality filter device to week
The bring influence of noise of collarette border.
For this purpose, the present invention at least has the important inventive point of following two:
(1) the organism percentage composition based on fish bowl water determines whether to trigger water quality filter device, meanwhile, also exist
When personnel amount where fish jar in house is less, since voice amplitude is relatively small, house is relatively quiet, closes water quality at this time
Filter plant is to avoid to causing noise pollution in relatively quiet house；
(2) being applied in combination by the double-deck recognition mode cuts down the operand of target identification, to improve identification from level to level
The rate of operation.
According to an aspect of the present invention, a kind of filtering control sewage water treatment method is provided, this method comprises: providing one kind
Filtering based on organism content detection controls sewage disposal system, and the personnel where to fish jar in house are customized detection
Data basis on, the organism percentage composition based on fish bowl water determine whether trigger water quality filter device, meanwhile, also
When the personnel amount where fish jar in house is less, water quality filter device is closed to avoid to causing in relatively quiet house
Noise pollution, thus weaken water quality filter device to ambient enviroment bring influence of noise, the system comprises:
Composition detection equipment, the water level of fish jar is set hereinafter, for in fish jar water body carry out real-time component detection,
To obtain organism percentage composition, and export the organism percentage composition, wherein the organism percentage composition is
Percentage occupied by the intracorporal organic body weight of per unit weight water in fish jar；
Water analysis equipment is connect with the composition detection equipment, for receiving the organism percentage composition, and
When the organism percentage composition is more than or equal to preset percentage threshold value, the bad signal of water quality is issued, is also used to have described
When body percentage composition is less than preset percentage threshold value, water quality normal signal is issued；
The upper edge of fish jar is arranged in CCD sensing equipment, for carrying out image sensing to the outdoor scene in house where fish jar,
To obtain and export house real scene image；
Curve detection equipment is connect with the CCD sensing equipment, real to the house for receiving house real scene image
The maximum curve of radian is detected in scape image, to obtain and export the corresponding radian of the curve using defeated as target radian
Out；
Curve processing equipment is connect with the curve detection equipment, for receiving the house real scene image and the mesh
Radian is marked, and curve adjustment processing is carried out to the house real scene image based on the target radian, to obtain simultaneously curve of output
Adjust image.
