Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
According to the sludge conditioning method provided by the embodiment of the disclosure, the change of the viscosity value in the sludge conditioning process is detected on line, the fluctuation value of the first viscosity data is determined to meet the condition that the sludge and the conditioner react completely, the sludge stirring is stopped, the time point when the sludge and the conditioner react completely can be accurately determined, the problem that the sludge dewatering effect is poor due to the fact that the error generated by judging the reaction end point of the sludge and the conditioner by means of artificial experience is avoided, and the problem that the end point when the conditioner and the sludge react completely is inaccurate due to the fact that the simple sludge dewatering detection is adopted is avoided, so that the problems of poor sludge dewatering effect and increased energy consumption are solved, and the sludge dewatering effect is improved and the energy consumption is reduced.
The sludge conditioning method, the device, the electronic equipment and the storage medium provided by the embodiment of the disclosure are exemplified below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a sludge conditioning method according to an embodiment of the disclosure. The method is suitable for application scenes for conditioning the sludge. The method can be performed by the sludge conditioning device provided by the embodiment of the disclosure, and the sludge conditioning device can be realized in a software and/or hardware mode. As shown in fig. 1, the sludge conditioning method comprises the following steps:
s101, acquiring first viscosity data of the sludge after the conditioner is added in the stirring process.
Specifically, a conditioning agent is added into sludge to be conditioned, for example, a sludge conditioning tank, after the conditioning agent is added, the viscosity data of the sludge is correspondingly changed along with the stirring process, and at the moment, the first viscosity data of the sludge is detected to obtain the first viscosity data of the sludge in the stirring process after the conditioning agent is added.
Illustratively, a viscosity acquisition device is installed in the sludge conditioning tank, and first viscosity data of the sludge is acquired through the viscosity acquisition device so as to acquire the first viscosity data of the sludge in the stirring process after the conditioner is added.
Wherein the conditioning agent comprises at least one of polyacrylamide, chitosan and starch. For example, when conditioning sludge, adding any one conditioner selected from polyacrylamide, chitosan and starch into a sludge conditioning tank; or adding any two conditioning agents of polyacrylamide, chitosan and starch into the sludge conditioning tank; or adding polyacrylamide, chitosan and starch into the sludge conditioning tank; the embodiments of the present disclosure are not particularly limited thereto.
In some embodiments, obtaining first viscosity data of sludge after adding a conditioning agent during agitation includes:
and acquiring first viscosity data of the sludge in the stirring process at intervals of a preset time length.
Specifically, the first viscosity data of the sludge during the stirring process is obtained by a viscosity acquisition device such as, but not limited to, a viscosity sensor provided in the sludge conditioning tank. The viscosity sensor may be configured to acquire first viscosity data of the sludge during the stirring process at a certain frequency, for example, at intervals of a preset duration, for example, every 1 second.
In some embodiments, the first viscosity data of the sludge during the stirring process may also be obtained in real time. And compared with the method for acquiring the first viscosity data of the sludge in the stirring process in real time, the method for acquiring the first viscosity data of the sludge in the stirring process by setting the interval preset time length can reduce the power consumption of the viscosity sensor.
In other embodiments, other technical means known to those skilled in the art may be used to obtain the first viscosity data of the sludge during the stirring process, which is not specifically limited herein.
S102, acquiring a first viscosity data fluctuation value based on the first viscosity data.
Specifically, in combination with the above, first viscosity data of the primary sludge in the stirring process is obtained every interval for a preset period of time, and a change value of the first viscosity data obtained in two adjacent times is used as a first viscosity data fluctuation value.
Illustratively, the first viscosity data of the sludge during agitation is set to be acquired every 1 second. For example, the first viscosity data acquired at 5 th second is N1, the first viscosity data acquired at 6 th second is N2, the first viscosity data acquired at 7 th second is N3, the change values of N2 and N1 are the first viscosity data fluctuation values, and the change values of N3 and N2 are the first viscosity data fluctuation values.
Thereby, a first viscosity data fluctuation value is obtained from the first viscosity data.
S103, determining that the fluctuation value of the first viscosity data meets the condition that the sludge and the conditioner react completely, and stopping sludge stirring.
Specifically, whether the condition that the sludge is completely reacted with the conditioner is satisfied is judged based on the obtained first viscosity data fluctuation value. If the condition that the sludge and the conditioner react completely is judged to be met based on the fluctuation value of the first viscosity data, the sludge and the conditioner can be determined to react completely, and the stirring of the sludge is stopped so as to carry out the next treatment of the sludge. If the condition that the sludge and the conditioner react completely is judged to be not met based on the fluctuation value of the first viscosity data, the condition that the sludge and the conditioner react incompletely can be determined, and then the sludge stirring is continued.
Therefore, the method for detecting the viscosity value of the sludge is simple, the problem of poor sludge dewatering effect caused by the error generated by judging the reaction end point of the sludge and the conditioner by means of artificial experience is avoided, and the problem of inaccurate end point of the complete reaction of the conditioner and the sludge by means of simple sludge dewatering detection is avoided, so that the problems of poor sludge dewatering effect and increased energy consumption are solved.
In addition, problems in the sludge conditioning process can be found in time according to the online detection viscosity data, and responses can be made in time. For example, the stirring speed is unreasonably set, so that the fluidity of the sludge is small, the viscosity value of the sludge does not change greatly before and after the conditioner is added, and at the moment, the stirring speed is unreasonably judged, and the stirring speed is increased.
In some embodiments, determining that the first viscosity data fluctuation value satisfies a condition that the sludge is fully reacted with the conditioning agent, stopping sludge agitation comprises:
and determining that the fluctuation value of the first viscosity data is smaller than a first fluctuation threshold value and lasts for a first time period, and stopping sludge stirring.
Specifically, based on the obtained first viscosity data fluctuation value, when the first viscosity data fluctuation value is smaller than a first fluctuation threshold value and the first time is continued, the conditioner and the sludge are determined to be completely subjected to conditioning reaction, at the moment, the sludge stirring is stopped, and the sludge can be subjected to the next treatment.
For example, the fluctuation value of the first viscosity data is smaller than the first fluctuation threshold value, for example, 1, within a first time period, for example, within 30 seconds, and the viscosity data is judged to be basically unchanged or changed very weakly in the sludge reaction process, namely, the viscosity of the sludge is stabilized, and at the moment, the conditioner and the sludge are determined to be completely subjected to conditioning reaction, and the sludge stirring is stopped.
Illustratively, fig. 2 is a graph of viscosity values over time during conditioning of a sludge provided by embodiments of the present disclosure. In fig. 2, the abscissa represents the reaction time T in S, the ordinate represents the viscosity CP in mpa×s. As shown in fig. 2, conditioning agent was added at 100s as indicated by the arrow, after which first viscosity data was obtained once every second. The viscosity of the sludge continuously obtained within 570s-600s is basically stable, namely the fluctuation value of the first viscosity data is basically unchanged or is changed very weakly within 30s, at the moment, the complete conditioning reaction of the conditioner and the sludge can be determined at 600s, and the stirring of the sludge can be stopped.
In some embodiments, the sludge conditioning method further comprises:
obtaining the solid content in the sludge;
and determining the addition of the corresponding amount of the conditioner based on the corresponding relation between the solid amount in the sludge and the addition amount of the conditioner.
Specifically, the water content of the sludge is obtained before the conditioner is added, and the solid content of the sludge is determined by the water content of the sludge. After the solid content of the sludge is obtained, the corresponding relation between the solid content of the sludge and the addition amount of the conditioner can be directly inquired, and the addition of the conditioner with the corresponding amount is determined according to the corresponding relation. Therefore, the solid quantity of the sludge to be conditioned is determined, and the corresponding quantity of the conditioner is added, so that the optimal conditioning effect is ensured, and the sludge dewatering effect is improved.
The corresponding relation between the solid amount of the sludge and the addition amount of the conditioner can be calibrated in advance. The water content of the obtained sludge can be detected by means well known to those skilled in the art, and is not described in detail herein.
In some embodiments, prior to obtaining the first viscosity data of the sludge after adding the conditioning agent during the agitation, the sludge conditioning method further comprises:
acquiring second viscosity data of sludge without conditioner in the stirring process;
and determining that the fluctuation value of the second viscosity data is smaller than a second fluctuation threshold value for a second duration based on the second viscosity data, and triggering to execute the acquisition of the first viscosity data of the sludge added with the conditioner in the stirring process.
Specifically, stirring of the sludge is started at a constant rotational speed before adding the conditioner to the sludge to be conditioned, for example, in a sludge conditioning tank, and second viscosity data of the sludge to which the conditioner is not added during stirring is measured.
And determining a second viscosity data fluctuation value based on the acquired second viscosity data, and when the acquired second viscosity data fluctuation value is smaller than a second fluctuation threshold value, continuing for a second duration. For example, the first viscosity data fluctuation values are smaller than the second fluctuation threshold value, for example, 0.4, within the second time period, for example, within 20 seconds, so that the viscosity of the sludge can be judged to be stable, the sludge can be determined to be uniformly mixed, and then the conditioner is added into the sludge, so that the conditioner is favorably contacted with the sludge sufficiently, the reaction rate is favorably improved, and the sludge conditioning efficiency is improved.
In some embodiments, prior to obtaining the first viscosity data of the sludge after adding the conditioning agent during the agitation, the sludge conditioning method further comprises:
obtaining the viscosity value and capillary dehydration time of each group of sludge samples after the reaction of a plurality of groups of sludge samples and the conditioner is completed, wherein the volumes of the sludge samples are the same, and the volumes of the conditioners added by the sludge samples in different groups are different;
determining a correlation coefficient between the viscosity value and the capillary dewatering time based on the viscosity value and the capillary dewatering time of each set of sludge samples;
and determining that the correlation coefficient is greater than or equal to a correlation coefficient threshold value, and triggering and executing to acquire first viscosity data of the sludge added with the conditioner in the stirring process.
Specifically, the same sludge sample is taken and divided into multiple groups, such as, but not limited to, five groups of sludge samples. And after the sludge samples of each group are reacted with the conditioner completely, obtaining the viscosity value and capillary dehydration time of the sludge samples of each group after the sludge samples of each group are reacted with the conditioner completely.
Illustratively, the five sets of sludge samples include set a, set B, set C, set D, and set E. Adding a first volume of conditioner to the group A sludge samples, adding a second volume of conditioner to the group B sludge samples, adding a third volume of conditioner to the group C sludge samples, adding a fourth volume of conditioner to the group D sludge samples, and adding a fifth volume of conditioner to the group E sludge samples. After the complete reaction of each group of sludge samples with the conditioner is determined, the viscosity value and capillary dewatering time of each group of sludge samples are measured to obtain the viscosity value and capillary dewatering time of each group of sludge samples after the completion of the reaction of the plurality of groups of sludge samples with the conditioner.
After the viscosity value and the capillary dewatering time of each group of sludge samples are obtained, the viscosity value and the capillary dewatering time of each group of sludge samples are input into Excel JMP data processing software for data correlation analysis, so that the corresponding correlation coefficient R is obtained 2 . When the correlation coefficient R 2 When the viscosity value is larger than or equal to a correlation coefficient threshold value, for example, 0.9, the viscosity value and the capillary dewatering time can be judged to have stronger correlation, namely, the acquired data are effective, and the sludge can be conditioned by adopting the sludge online conditioning method provided by the embodiment of the disclosureCan realize better sludge conditioning effect. When the correlation coefficient R 2 The viscosity value and the capillary dewatering time are considered to have weak correlation or no correlation when the viscosity value is smaller than the correlation coefficient threshold value, for example, 0.9, the effectiveness of the viscosity value in the sludge conditioning process is low or invalid in the online detection, and the sludge is conditioned by adopting the sludge online conditioning method provided by the embodiment of the disclosure, so that the dewatering effect of the sludge is poor.
Illustratively, fig. 3 is a graph of viscosity values and capillary dewatering time for various groups of sludge samples after completion of a reaction of the sludge samples with a conditioner, as provided by embodiments of the present disclosure. Fig. 4 is a graph of a fitted correlation of sludge viscosity values and capillary dewatering time provided in an embodiment of the present disclosure. In fig. 3, the abscissa represents the volume V of the conditioning agent in ml, the left side of the ordinate represents the capillary dewatering time CTS in S, and the right side viscosity CP in mPa x S; in fig. 4, the abscissa represents the fine dewatering time CTS in S, and the ordinate represents the viscosity CP in mpa×s. The curve obtained in fig. 4 is obtained by performing correlation fitting on the viscosity values and capillary dewatering time data obtained from the multiple sets of sludge samples in fig. 3. As shown in FIG. 4, the capillary dewatering time CST of sludge is positively correlated with the viscosity of sludge, and the correlation coefficient R 2 And 0.902, which shows that the capillary dehydration time of the sludge has a strong correlation with the viscosity of the sludge.
The sludge conditioning method provided by the embodiment of the disclosure comprises the steps of obtaining first viscosity data of sludge added with a conditioner in a stirring process; acquiring a first viscosity data fluctuation value based on the first viscosity data; and determining that the fluctuation value of the first viscosity data meets the condition that the sludge and the conditioner react completely, and stopping sludge stirring.
