Fig. 2 is the process flow diagram of the measuring method embodiment two of total organic carbon in waterbody of the present invention.As shown in Figure 2, the measuring method of present embodiment total organic carbon in waterbody based on the measuring method embodiment one of above-mentioned total organic carbon in waterbody, includes step 1-step 3, and its difference is: also comprised before step 1:
Step 1 ', in experiment pool, inject ozone, so that the organic carbon in ozone and water body reaction is luminous.Concrete, the pairing voltage signal of organic carbon in the acquisition water body for convenience, step 1 in the present embodiment ' ozone is injected in the water body in the experiment pool, ozone will react with organic carbon and luminous, and the big more light intensity of the concentration of total organic carbon in waterbody is just strong more.
Step 1 is specially: the light that the water body in the experiment pool is sent detects, and light is converted to voltage signal.Concrete, by step 1 ' light that the water body in the experiment pool is sent, the light intensity that step 1 is sent the water body in test experience pond, and be voltage signal with detected smooth corresponding conversion, thereby the pairing voltage signal of organic carbon in the water body can be obtained easily.
Further, carry out Integral Processing, before the area value that obtains the voltage signal correspondence, also comprise at step 2 pair voltage signal:
Step 2 ', voltage signal is removed the processing of making an uproar.Concrete, because in the water body to experiment pool detects with the process that obtains voltage signal, the process of detecting can be subjected to extraneous influence of various factors, thereby need remove the processing of making an uproar to detected voltage signal, for example, can handle voltage signal by one-dimensional wavelet transform, effectively voltage signal is removed the processing of making an uproar.

Based on technique scheme, optionally, as shown in Figure 3, the step 1 in the present embodiment comprises following concrete steps:
Step 11, judge that voltage signal is whether stable.Concrete, judge by step 11 pair detected voltage signal, determine whether voltage signal is in steady state (SS).For example: the relative standard deviation that can calculate continuous a plurality of voltage signals; If relative standard deviation, determines then that voltage signal is in steady state (SS) less than default standard deviation.In a period of time scope, can detect different corresponding constantly voltage signals, calculate the relative standard deviation of continuous a plurality of voltage signals then, relative standard deviation that calculates and the standard deviation of presetting are compared, if relative standard deviation can determine then that less than default standard deviation detected voltage signal is in steady state (SS).
Step 12, if voltage signal be in steady state (SS), in experiment pool, do not continuing under the situation of injection water body, detect first voltage signal of the organic carbon correspondence in the water body, until the ratio of first voltage signal and the mean value of the voltage signal that is in steady state (SS) less than pre-set threshold value.Concrete, after judging voltage signal and being in steady state (SS), then stop in experiment pool, to continue to inject water body, and begin first voltage signal of the organic carbon correspondence in the detection record water body simultaneously.Because continue in the experiment pool to inject ozone, the content of the organic carbon in the water body reduces gradually, the light intensity that the water body of experiment pool sends also dies down gradually, thereby causes the magnitude of voltage of detected first voltage signal to reduce gradually.When the ratio of first voltage signal and the mean value of the voltage signal that is in steady state (SS) during less than pre-set threshold value, detected all magnitudes of voltage are first voltage signal.
Step 13, after the ratio of the magnitude of voltage of first voltage signal and the mean value of the voltage signal that is in steady state (SS) is less than pre-set threshold value, in experiment pool, continuing to inject under the situation of water body, detect second voltage signal of the organic carbon correspondence in the water body, mxm. appears until detecting second voltage signal, the size of the magnitude of voltage of obtained previous moment when wherein, mxm. is detected second voltage signal magnitude of voltage that occurs previous moment for the first time greater than constantly magnitude of voltage of back one.Concrete, after the ratio of the magnitude of voltage of first voltage signal and the mean value of the voltage signal that is in steady state (SS) is less than pre-set threshold value, will continues to inject water body again in the experiment pool, and begin second voltage signal of the organic carbon correspondence in the detection record water body simultaneously.Owing to injected new water body in the experiment pool, the content of the organic carbon in the experiment pool is increased, the light intensity that the water body of experiment pool sends is grow gradually also, thereby causes the magnitude of voltage of detected second voltage signal to increase gradually.In detecting the process of second voltage signal, when the magnitude of voltage that detected previous moment occurs for the first time during greater than constantly magnitude of voltage of back one, as mxm., detected all magnitudes of voltage are second voltage signal with the magnitude of voltage of this previous moment.
And the step 2 in the present embodiment is specially: first voltage signal and second voltage signal are carried out Integral Processing.Concrete, the area value that obtains in the step 2 comprises two parts, i.e. the area value sum of the area value of the first voltage signal correspondence and the second voltage signal correspondence.
The measuring method of present embodiment total organic carbon in waterbody, by after obtaining voltage signal in judgement and being in steady state (SS), detect the voltage signal of the organic carbon correspondence in the water body in the different time sections again, can obtain the area value of voltage signal correspondence more accurately and effectively, thereby can obtain the concentration of total organic carbon in waterbody more accurately, more help improving the reliability of the measuring method of present embodiment total organic carbon in waterbody.
Based on technique scheme, optionally, present embodiment step 1 is specially: according to default sample frequency the water body in the experiment pool is detected, wherein, sample frequency is the relative standard deviation frequency values hour of continuous a plurality of voltage signals.
Particularly, in the process that the water body in the experiment pool is detected, can detect according to default sample frequency, wherein, this employing frequency is a pairing frequency values when the numerical value of the relative standard deviation of detected voltage signal is minimum value.By adopting default sample frequency that the voltage signal of the organism correspondence in the experiment pool is detected, can obtain the voltage signal of organic carbon correspondence more accurately; And, can more accurately be easy to calculate the area value of voltage signal correspondence owing to adopt default sample frequency to detect.
Further, the measuring method of present embodiment total organic carbon in waterbody both can the continuous detection experiment pool in the concentration of total organic carbon, can also adopt the concentration of total organic carbon in the discontinuous mode test experience pond.When adopting discontinuous mode, step 1 will detect the water body in the experiment pool according to default sample frequency, concrete, above-mentioned steps 12 and step 13 can adopt following method to obtain: according to default sample frequency the water body in the experiment pool is carried out the interval and detect, to obtain a plurality of voltage signals, wherein, the number of voltage signal is the default number of times that detects.Concrete, the interval detection can be configured in advance and number of times will be detected, detect the voltage signal of correspondence in the different time sections then at interval according to default sample frequency.Step 2 in the present embodiment is specially: each voltage signal is carried out Integral Processing, to obtain the area value of each voltage signal correspondence.Concrete, the voltage signal in each time period is carried out Integral Processing, thereby can obtain each voltage signal corresponding area value in the time period at place separately.
Further again, the step 3 in the present embodiment can be specially:
Maximum area value and minimum area value in step 31, the removal area value;
Step 32, remaining area value is averaged, to obtain the average area value;
Step 33, according to average area value and default concentration formula, calculate the concentration of the total organic carbon in the water body.Concrete, behind the area value by each voltage signal correspondence of step 2 acquisition, maximum area value and minimum area value are removed; Then, can calculate residual area value sum, in the hope of the average area value of above-mentioned area value; At last, the average area value is brought into the concentration formula, just can calculates the concentration of the total organic carbon in the water body.
Further, default concentration formula in the present embodiment can adopt the formula that configures in advance, also can carry out the scene and set in the process of primary detection voltage signal.Particularly, in order to set default concentration formula in advance, the measuring method of present embodiment total organic carbon in waterbody also comprised before step 33:
Step 33 ', set default concentration formula, be specially:, obtain default concentration value and the linear relationship between the average area value, with the concentration formula that obtains presetting according to average area value and default concentration value.Concrete, can be complementary with default concentration value by calculating the average area value that obtains, make the average area value corresponding one by one, thereby can obtain the concentration value preset and the linear relationship between the average area value easily with the concentration value of presetting.For example: can detect the average area value twice, twice average area value will be distinguished corresponding different default concentration values, then, according to two groups of average area values and default concentration value, calculate default concentration formula.
The measuring method of present embodiment total organic carbon in waterbody detects the water body in the experiment pool by adopting default sample frequency, can obtain the voltage signal of organic carbon correspondence more accurately; And, can more accurately be easy to calculate the area value of voltage signal correspondence owing to adopt default sample frequency to detect.By setting default concentration formula, can set the concentration formula easily according to actual needs, thereby make the concentration value of the total organic carbon that calculates more accurate, more help improving the reliability of the measuring method of present embodiment total organic carbon in waterbody.
