Abstract
The invention discloses a method for determining a septic tank cleaning period based on the concentration change of liquid dung, which is applied to a multi-grid septic structure, wherein the multi-grid septic structure is provided with a plurality of septic bins, adjacent septic bins are communicated by using a water pipe, an inlet of the water pipe is arranged in the middle of a previous septic bin, and an outlet of the water pipe is communicated with the upper part of a next septic bin.
Description
Technical Field
The invention relates to the technical field of water supply and drainage for rural areas, in particular to a method for determining a septic tank cleaning period based on the concentration change of liquid dung.
Background
The design specification of water supply and drainage of buildings (GBJ15-88) requires that the cleaning period of a septic tank is 3-12 months, the actual design period is 3-9 months more, the acid fermentation period of the acid fermentation stage is 3 months, and the acid decline period is about 5 months.
The cleaning period of the septic tank is related to the temperature, air temperature, building properties, water quality and water quantity of the excrement and sewage. If the cleaning period is too long, the concentration of the septic tank is too high, which affects the normal fermentation and sewage treatment effect, even causes the overflow and blockage of the septic tank, and affects the environmental sanitation. If the cleaning period is too short, the cleaning cost is increased, and the resource waste is caused. In actual use, due to the fact that the use frequency, the sewage amount and the environmental factors cannot be predicted, the septic tank is cleaned completely according to experience or design period, and overflow, blockage and resource waste phenomena occur occasionally.
The septic tank used in the new rural area at present has limited volume, the proportion of liquid waste and solid waste thrown into the septic tank by rural families is unpredictable, the septic tank can be selected for detection when the volume of the waste in the septic tank is measured,
disclosure of Invention
The invention aims to provide a method for determining the cleaning period of a septic tank based on the concentration change of liquid dung, which can accurately detect the concentration in the septic tank.
In order to achieve the purpose, the invention provides the following technical scheme: a method for determining a septic tank cleaning period based on concentration change of liquid manure is applied to a multi-lattice septic structure, the multi-lattice septic structure is provided with a plurality of septic bins, adjacent septic bins are communicated through a water pipe, an inlet of the water pipe is arranged in the middle of a previous septic bin, and an outlet of the water pipe is communicated with the upper part of a next septic bin.
Furthermore, the concentration detection device comprises a sewage concentration sensor and a sewage concentration controller.
Furthermore, the infrared sensor is arranged in a water pipe between the first-stage decay cavity and the second-stage decay cavity.
Compared with the prior art, the invention has the beneficial effects that:
the septic tank cleaning period is judged by directly measuring the concentration of the liquid dung in the septic tank passing pipe of the septic tank, and the septic tank cleaning period is reliable and direct, so that the septic tank pretreatment effect is ensured, and the resource waste caused by experience judgment is avoided.
Drawings
FIG. 1 is a schematic of the present invention.
In the figure: a septic bin-1, a water pipe-2 and a concentration detection device-3.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to the attached drawings, the method for determining the septic tank cleaning cycle based on the concentration change of liquid dung is applied to a multi-grid septic structure, the multi-grid septic structure is provided with a plurality of septic bins 1, adjacent septic bins 1 are communicated by using a water pipe 2, an inlet of the water pipe 2 is arranged in the middle of the previous septic bin 1, an outlet of the water pipe is communicated with the upper part of the next septic bin 1, a concentration detection device is arranged in the water pipe 2 between the first septic chamber and the second septic chamber, the multi-grid septic structure is a multi-level septic device, rural liquid dung is firstly received in the first septic bin and then is sequentially conveyed to the second septic bin, the third septic bin and the fourth septic bin through the water pipe 2, liquid dung is firstly precipitated in the septic bin 1, impurities are located below, and water is conveyed to the second septic bin through the water pipe 2, The third-stage septic bin and the fourth-stage septic bin are communicated, the embodiment is different from the previous detection method, the previous detection septic bin 1 is a whole, a concentration detection device 3 is arranged at the lower part or the middle part or the upper part of the septic bin 1 with the integral structure, when the concentration detection device is arranged at the lower part, the concentration detection device 3 can send out a cleaning signal when the precipitate in the septic bin 1 does not reach the cleaning amount, when the concentration detection device is arranged at the middle part, the precipitate concentration in the septic bin 1 is low, water is excessive, the concentration detection device 3 positioned at the middle part can only detect the concentration of the precipitate, the excessive water can damage the structure of the whole septic bin, the water overflows to cause pollution, when the concentration detection device is arranged at the upper part, the detection precision is lower, the multi-lattice septic structure arranged in the embodiment is composed of a plurality of septic bins 1 which are sequentially communicated, the septic bins are communicated through a water passage 1, the septic bin at the first stage is used for precipitation, and when the excessive water enters the next-stage septic, when the excrement concentration in the first-stage septic bin is too large, the concentration detection device 3 in the water passing channel 2 can detect the concentration change, so that the septic bin 1 is prevented from being damaged by excessive water, the concentration of sediments can be timely cleared, the sediments can be timely cleaned, the detection effect is better, the method comprises the steps of detecting the transmissivity of the excrement liquid by using the concentration detection device, and calculating the concentration of suspended matters in the excrement liquid according to the transmissivity.
The concentration sensor is based on the principle of a scattered light type suspended matter measuring method, the sewage concentration can be continuously and accurately measured by applying an ISO7027 method, and the concentration detection device comprises a sewage concentration sensor and a sewage concentration controller.
The sewage concentration sensor is designed and manufactured by adopting the principle of a scattered light type suspended matter measurement method. When a beam of light is emitted into a water sample, light is scattered due to suspended substances in the water sample, the intensity of the scattered light in the direction perpendicular to the incident light is measured and compared with an internal calibration value, so that suspended substances in the water sample are calculated, and a final value is output through linearization treatment. The relationship between the transmittance and the concentration of the liquid manure suspension is as follows: and (4) proportional relation.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
