Example 1
Referring to fig. 1, fig. 1 is a schematic flow chart of a method for evaluating carbon source performance according to an embodiment of the present disclosure. The carbon source performance evaluation method comprises the following steps:
s101, obtaining a carbon source to be evaluated.
S102, performing multi-type tests on the carbon source to be evaluated to obtain a plurality of test results.
S103, judging whether the multiple test results meet the respective corresponding evaluation standards, if so, executing a step S104; if not, the flow is ended.
And S104, outputting the evaluation qualified result.
In this embodiment, the method can be used for performance evaluation of coupling modification of a Carbon Source (CS) and Activated Sludge (AS) for heterotrophic denitrification, and is also beneficial to improving denitrification utilization efficiency.
And S105, feeding the carbon source to be evaluated on a computer.
In the embodiment of the present application, the execution subject of the method may be a computing system such as a computer and a server, and the embodiment is not limited in any way.
In this embodiment, an execution subject of the method may also be an intelligent device such as a smart phone and a tablet computer, which is not limited in this embodiment.
It can be seen that, by implementing the carbon source performance evaluation method described in this embodiment, multiple types of automated (human-computer interactive) tests can be performed on the carbon source to be evaluated, and the obtained multiple automated (human-computer interactive) evaluation results can be automatically evaluated, so that the evaluation qualified result is output when the evaluation of the carbon source to be evaluated is qualified. Therefore, the implementation of the embodiment can automatically (man-machine interactive) evaluate the performance of the carbon source, so that the quality control of the carbon source is realized, and the improvement of the efficiency of the carbon source use and the standardization of the quality control are facilitated.
Example 2
Please refer to fig. 2, fig. 2 is a schematic flow chart of a method for evaluating carbon source performance according to an embodiment of the present application. As shown in fig. 2, the method for evaluating the performance of a carbon source comprises the following steps:
s201, obtaining a carbon source to be treated.
S202, identifying the carbon source to be processed to obtain the carbon source variety.
In this example, the carbon source types were classified into two types:
firstly, if the carbon source is acetic acid, acetates (sodium acetate), monohydric alcohols (such as methanol) and dihydric alcohols (such as ethanol), the carbon source is short-chain and easy to utilize;
② long-chain carbon source if the carbon source is polyhydric alcohol (such as propanol and glycerol), saccharide (such as glucose and sucrose), starch (flour and corn steep liquor), and composite carbon source (prepared by mixing more than one single product).
And S203, when the carbon source is a long-chain carbon source, activating the carbon source to be processed to obtain the carbon source to be evaluated.
In this example, the activation modification of peat was performed on a long-chain carbon source. If the carbon source is the above-mentioned second type long-chain carbon source, it needs to be activated because it is a macromolecular organic carbon source and its utilization rate as a direct carbon source is low. If the carbon source is the short-chain easily-utilized carbon source of the first class, the carbon source can be directly and quickly utilized and absorbed due to the fact that the carbon source is organic acid or organic alcohol which is easy to degrade and utilize by small molecules, and the carbon source can directly enter a simulation evaluation link of different concentrations and dosages of the carbon source without activation so as to evaluate the performance of the carbon source.
S204, performing physical and chemical index detection on the carbon source to be evaluated to obtain a first test result.
In this example, the method first adds a carbon source (volume about 200-500mL), then measures the pH of the carbon source, and manually assays COD, BOD, TN (to evaluate the B/C ratio, C/N ratio, B/N ratio, i.e., carbon source equivalent and its biodegradability). Wherein, the method quantitatively judges whether the conformity indexes are as follows: the COD equivalent is not less than 20 ten thousand, the BOD/COD ratio is more than 0.7, the COD/TN ratio is not less than 500: 1, the pH value is within the range of 2.0-8.0. If so, the evaluation criteria are considered to be met, and the subsequent steps are executed.
S205, performing biotoxicity detection on the carbon source to be evaluated to obtain a second test result.
In this embodiment, the method may be to introduce the clear water in advance, and then add the carbon source (gradually increasing the gradient of the mass concentration at 100-. On the basis, whether the compliance indexes are as follows is judged quantitatively: whether the vital signs (life habits) of the fish indicator organism b1 are normal or not is observed for 0.5-2 h (if the vital signs are normal, the condition that if the carbon source is added to a certain concentration range in the range of 1, no harm is caused to microorganisms can be indirectly judged). If so, the evaluation criteria are considered to be met, and the subsequent steps are executed.
As an alternative embodiment, the step of performing a biotoxicity test on the carbon source to be evaluated to obtain the second test result comprises:
and (4) carrying out clear water aeration on the carbon source to be evaluated to detect the biotoxicity, and obtaining a second test result.
S206, carrying out denitrification load detection on the carbon source to be evaluated to obtain a third test result.
In this embodiment, the method may first add about 1000-3000mL of active sludge source, and synchronously add carbon source (with a mass concentration of 80-500mg/L), and then stir it. And (3) manually sampling and detecting the initial and final TN concentration change of the reaction by reacting for 2-5 h. On the basis, whether the compliance indexes are as follows is judged quantitatively: whether the removal concentration of TN reaches the expectation and whether the ton water of the removal unit TN is lower than the expectation is used as a qualitative (or semi-quantitative) index for evaluating the denitrification efficiency. If so, the evaluation criteria are considered to be met, and the subsequent steps are executed.
As an alternative embodiment, the step of performing denitrification load detection on the carbon source to be evaluated to obtain a third test result comprises:
and carrying out anoxic stirring on the carbon source to be evaluated to detect the denitrification load, and obtaining a third test result.
And S207, carrying out COD biochemical degradation limit detection on the carbon source to be evaluated to obtain a fourth test result.
In this embodiment, the method may first add about 1000-3000mL of active sludge source, then add carbon source (with a mass concentration of 80-500mg/L), and then aerate it. After the reaction is carried out for 10-18 h, the change of the filtered COD (i.e. sCOD) concentration at the initial and final reaction stages is detected by manual sampling. On the basis, whether the compliance indexes are as follows is judged quantitatively: the removal rate of sCOD is more than 85 percent, and the concentration of residual COD (sCOD) after the final filtration of the reaction is less than 50mg/L, which is used as a qualitative (or semi-quantitative) index of the biochemical degradation limit of COD.
As an alternative embodiment, the step of performing COD biochemical degradation limit detection on the carbon source to be evaluated to obtain the fourth test result comprises:
and carrying out aerobic aeration on the carbon source to be evaluated to detect the biochemical degradation limit of COD so as to obtain a fourth test result.
S208, judging whether the first test result, the second test result, the third test result and the fourth test result meet respective corresponding evaluation criteria, if so, executing steps S209-S210; if not, the flow is ended.
And S209, outputting the evaluation qualified result.
S210, feeding the carbon source to be evaluated on a machine.
In this embodiment, the method may be used to normally add the carbon source on the machine after the evaluation that the performance of the native (or modified) carbon source is qualified. If the carbon source is not qualified, the carbon source needs to be replaced and reselected for identification modification and new evaluation, and the on-machine administration can be carried out after the evaluation is qualified.
It can be seen that, by implementing the carbon source performance evaluation method described in this embodiment, multiple types of automated (human-computer interactive) tests can be performed on the carbon source to be evaluated, and the obtained multiple automated (human-computer interactive) evaluation results can be automatically evaluated, so that the evaluation qualified result is output when the evaluation of the carbon source to be evaluated is qualified. Therefore, the implementation of the embodiment can automatically (man-machine interactive) evaluate the performance of the carbon source, so that the quality control of the carbon source is realized, and the improvement of the efficiency of the carbon source use and the standardization of the quality control are facilitated.

In this embodiment, the detection process in the physicochemical index detection subsystem 41 is as follows: starting the pump 32, the valve C2 (closing the valve C1) and the stop valve a1, adding a carbon source (the volume is about 200-: the COD equivalent is not less than 20 ten thousand, the BOD/COD ratio is more than 0.7, the COD/TN ratio is not less than 500: 1, the pH value is within the range of 2.0-8.0.

After reacting for 2-5 h, manually sampling and detecting the initial and final TN concentration change of the reaction, and quantitatively judging whether the conformity indexes are as follows: whether the removal concentration of TN reaches the expectation and whether the ton water of the removal unit TN is lower than the expectation is used as a qualitative (or semi-quantitative) index for evaluating the denitrification efficiency. If the above-mentioned match, enter the next procedure.

After the reaction is carried out for 10-18 h, the change of the filtered COD (namely sCOD) concentration at the initial and final reaction stages is detected by manual sampling, and whether the compliance index is as follows is judged quantitatively: the removal rate of sCOD is more than 85 percent, and the concentration of residual COD (sCOD) after the final filtration of the reaction is less than 50mg/L, which is used as a qualitative (or semi-quantitative) index of the biochemical degradation limit of COD.

In this embodiment, when the carbon source is the above-mentioned second type long-chain carbon source, since all of the carbon sources are macromolecular organic carbon sources and the utilization rate of the carbon sources as direct carbon sources is low, activation is required, and the activation operation is as follows: the activated sludge efficiency-improving system 2 needs to be started, activated sludge is supplemented into the carbon source storage tank 31 for endogenous activation, the amount of the added sludge is such that the MLSS concentration in the activated sludge 31 is 500-1000 mg/L (MLVSS is 200-600 mg/L; the nitrate nitrogen concentration in the activated sludge static sedimentation liquid is less than 10mg/L), and the enzymatic activation nutrient 6 is synchronously supplemented into the carbon source storage tank 31. The activation time of the mud/carbon source/yeast three-phase mixed material is generally 8-24 h. If the carbon source is a short-chain easily-utilized carbon source of the first class: since the carbon source is organic acid or organic alcohol which is easy to degrade and utilize by small molecules and can be directly and quickly utilized and absorbed, the carbon source can directly enter a simulation evaluation link of carbon sources with different concentrations and dosages without activation so as to evaluate the performance of the carbon source.
In this embodiment, after the performance of the native (or modified) carbon source is determined to be in accordance with the performance, the pump 32 and the valve c1 (the valve c2 is closed) are turned on, and the carbon source is normally added into the biochemical sludge source system 1.
