[0077] The data acquisition module includes an activity analysis unit, a porosity analysis unit, and an oxygen content unit;

[0078] The activity analysis unit performs activity analysis on the packing biospheres in the filter tank and obtains the activity comparison value of the packing biospheres.

[0079] When the ambient temperature of the rapid separation system is in the low temperature range, the water volume per unit sample volume in the filter tank of the rapid separation system is diverted to the analysis container through the diversion channel to obtain the first water activity analysis sample.

[0080] It should be noted here that:

[0081] In the application, the specific low-temperature range was set as 8 degrees Celsius to 10 degrees Celsius;

[0082] In this application, the filler biosphere is specifically a biological material used by the rapid separation system to adsorb suspended matter in the water during the water treatment process;

[0083] Obtain the average area ratio of attached biospheres in the sample packing material;

[0084] Specifically as follows:

[0085] In the first water body activity analysis sample, nk packing biospheres were selected as sample packing biospheres and named as sample packing biospheres from n1 to nk.

[0086] It should be noted here that:

[0087] In this application, nk represents the number of selected sample packing biospheres;

[0088] Obtain the area ratio of the surface attachments on the n1th surface;

[0089] The area of ​​the surface covering particles of the n1th sample filler biosphere is used to obtain the area value of the first filler biosphere, and the surface area value of the n1th sample filler biosphere is used to obtain the area value of the second filler biosphere.

[0090] Calculate the ratio of the area of ​​the first packer biosphere to the area of ​​the second packer biosphere to obtain the surface attachment area ratio of the n1th sample packer biosphere, and name it the n1th surface attachment area ratio.

[0091] Repeat the process of obtaining the surface attachment area ratio of the n1th sample, and obtain the surface attachment area ratio of the biospheres corresponding to the filler materials of the n2th to nk samples respectively, to obtain the surface attachment area ratio of the n2th to nk samples.

[0092] The average area ratio of the surface attachments from n1 to nk was calculated to obtain the average area ratio of the biospheres used as fillers in the sample.

[0093] A unit volume of water was extracted from the first water body activity analysis sample as a water body test subsample. The filler biospheres were then extracted from the water body test subsample to obtain filler biosphere samples.

[0094] The filler biosphere sample was imported into the COD assay kit, and the COD of the filler biosphere sample was measured. The COD value output by the assay was obtained to obtain the COD test value of the filler biosphere corresponding to the first water body activity analysis sample.

[0098] Where, T l s1 is the quantitative value of the first biosphere activity, Cod is the COD test value of the filler biosphere, Mjb is the average attached area ratio of the sample filler biosphere, and a1 is the set proportional coefficient and a1 is greater than 0.

[0099] When the ambient temperature of the rapid separation system is at the reference temperature, the water volume per unit sample in the filter tank of the rapid separation system is diverted to the analysis container through the diversion channel to obtain the second water activity analysis sample.

[0100] It should be noted here that:

[0101] In this application, the reference temperature is collectively defined as 20 degrees Celsius;

[0102] The COD test value of the biospheres and the average attachment area ratio of the biospheres in the second water body activity analysis sample were obtained respectively.

[0103] The activity quantification value of the second biosphere was obtained by calculating the COD test value of the biosphere corresponding to the second water body activity analysis sample and the ratio of the average attached area of ​​the biosphere to the sample biosphere.

[0104] The difference between the activity quantification values ​​of the first and second biospheres is calculated to obtain the biosphere activity comparison value of the filler material;

[0105] The porosity analysis unit acquires the porosity of the filter material in the filter tank and obtains a porosity comparison value of the filter material.

[0106] When the ambient temperature of the rapid separation system is in the low temperature range, a unit volume of filter material is selected from the filter tank as the first sample filter material.

[0107] Please see Figure 3 The first sample filter is placed in the feature test container, and the feature water level line is marked in the feature test container. Test liquid is added to the feature test container. When the liquid level of the test liquid is level with the feature water level line, the volume value of the added test liquid is obtained to obtain the first liquid volume value.

[0108] When the ambient temperature of the rapid separation system is at the reference temperature, a unit volume of filter material is selected from the filter tank as the second sample filter material.

[0109] The second sample filter is placed in the feature test container, and the feature water level line is marked in the feature test container. Test liquid is added to the feature test container. When the liquid level of the test liquid is level with the feature water level line, the volume value of the added test liquid is obtained to obtain the volume value of the second liquid.

[0110] Calculate the difference between the first liquid volume value and the second liquid volume value to obtain the porosity comparison value of the filter material;

[0111] The oxygen content unit acquires the oxygen content in the filtration tank and obtains a comparative value of oxygen content.

[0112] When the ambient temperature of the rapid separation system is in the low temperature range, the oxygen content value corresponding to the filter pool is obtained to obtain the first oxygen content value.

[0113] When the ambient temperature of the rapid separation system is at the reference temperature, the oxygen content value corresponding to the filter pool is obtained to obtain the second oxygen content value.

[0114] Calculate the difference between the first oxygen content value and the second oxygen content value to obtain the oxygen content comparison value;

[0115] The comparison values ​​of the activity of the packing biospheres, the porosity of the filter material, and the oxygen content are defined as the system's low-temperature start-up monitoring data.

[0116] The data acquisition module acquires the system's low-temperature startup monitoring data and transmits it to the data analysis module;

[0117] The data analysis module obtains system low-temperature startup analysis data based on the system's low-temperature startup monitoring data.

[0118] Acquire system low-temperature startup monitoring data;

[0119] Based on the system's low-temperature startup monitoring data, the comparison values ​​of the packing biosphere activity, the filter material porosity, and the oxygen content were obtained respectively.

[0120] The low-temperature pre-start coefficient of the rapid separation system was obtained by calculating the comparison values ​​of the activity of the packing biospheres, the porosity of the filter material, and the oxygen content.

[0121] The low-temperature pre-start coefficient of the speed separation system is calculated using the following formula:

[0122] Sfy = Shx + Kxd + Yhl * b1;

[0123] Wherein, Sfy is the low temperature pre-start coefficient of the rapid separation system, Shx is the activity comparison value of the packing biosphere, Kxd is the porosity comparison value of the filter material, Yh l is the oxygen content comparison value, and b1 is the set proportional coefficient with b1 being greater than 0.

[0124] Obtain the low-temperature pre-start coefficient threshold of the rapid separation system, and compare the low-temperature pre-start coefficient of the rapid separation system with the low-temperature pre-start threshold to obtain the low-temperature start-up analysis data of the system.

[0125] The threshold value for the low-temperature pre-start-up coefficient of the rapid separation system is obtained as follows:

[0126] The threshold values ​​for the activity of the packing biospheres, the porosity of the filter media, and the oxygen content were obtained respectively.

[0127] The threshold values ​​for the low-temperature pre-start coefficient of the rapid separation system were calculated by comparing the activity threshold of the packing biospheres, the porosity threshold of the filter material, and the oxygen content threshold.

[0128] The threshold value for the low-temperature pre-start-up coefficient of the speed separation system is calculated using the following formula:

[0129] Sfyy=Shxy+Kxdy+Yhly*b1;

[0130] Wherein, Sfyy is the threshold value of the low temperature pre-start coefficient of the rapid separation system, Shxy is the threshold value of the activity comparison value of the packing biosphere, Kxdy is the threshold value of the porosity comparison value of the filter material, Yh ly is the threshold value of the oxygen content comparison value, and b1 is the set proportional coefficient and b1 is greater than 0.

[0131] The numerical comparison process is as follows:

[0132] When the low-temperature pre-start coefficient of the fast separation system is less than or equal to the threshold of the low-temperature pre-start coefficient of the fast separation system, the fast separation system is judged to be in the first pre-start interval.

[0133] When the low-temperature pre-start coefficient of the fast separation system is greater than the threshold of the low-temperature pre-start coefficient of the fast separation system, the fast separation system is determined to be in the second pre-start interval.

[0134] It should be noted here that:

[0135] When the rapid separation system is in the first pre-start-up zone, the rapid separation system starts directly, which has no impact on the rapid separation and treatment effect of the water body.

[0136] When the rapid separation system is in the second pre-start-up zone, the rapid separation system starts directly, which affects the rapid separation and treatment effect of the water body.

[0137] The data analysis module acquires the system's low-temperature startup analysis data and sends it to the system startup module;

[0138] The system startup module formulates a startup strategy based on the system's low-temperature startup analysis data;

[0139] Acquire system low-temperature startup analysis data;

[0140] When the speed separation system is in the first pre-start interval, the speed separation system will start normally directly;

[0141] When the speed-distribution system is in the second pre-startup zone, the specific startup strategy of the speed-distribution system is as follows:

[0142] The rapid detection system issued a warning about excessively low ambient temperature.

[0143] The rapid separation system automatically adjusts the number of biological balls in the filter tank upwards;

[0144] The rapid separation system automatically adjusts the porosity of the filter media in the filter tank downwards;

[0145] The rapid separation system automatically adjusts the oxygen content in the filtration tank upwards.

[0146] In this application, if a corresponding calculation formula appears, the above calculation formula is a dimensionless calculation. The weighting coefficient, proportional coefficient and other coefficients in the formula are set to quantify each parameter to obtain a result value. The size of the weighting coefficient and proportional coefficient is only required to not affect the proportional relationship between the parameter and the result value.
