Description

Technical Field

[0001] The present invention relates to the technical field of facility operation health assessment, and particularly to a device, method, equipment and medium for assessing the operation health of rural domestic sewage treatment facilities. Background Art

[0002] Due to reasons such as a large number of rural sewage treatment facilities being scattered, with complex treatment processes and equipment types, if one wants to analyze the overall operation status of each rural sewage treatment facility, professional technical personnel are required to be on duty in real time and conduct detailed observation and tracking of the operation status, which poses extremely high requirements for the number and technical quality of maintenance and management personnel.

[0003] However, based on the characteristics of a large number of rural sewage treatment facilities being scattered, the rural sewage treatment facilities in China generally adopt an unattended periodic inspection method for management, lacking professional technical personnel. At the same time, due to the lack of scientific methods and tools for assessing the operation health of facilities, it is difficult to quickly judge the operation health status of numerous rural sewage treatment facilities, and it is difficult to discover operation problems, which also brings great difficulties to the timely handling of problems with rural sewage treatment facilities and the continuous optimization of operation, thus restricting the rapid promotion of high-quality management of rural domestic sewage in the region.

[0004] Therefore, based on the need for the operation management of a large number of decentralized unattended rural sewage treatment facilities, there is an urgent need to construct a comprehensive operation health analysis method and tool for rural domestic sewage treatment facilities, which can automatically analyze the operation status of facilities and diagnose problems in real time, providing technical support for management personnel. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above deficiencies and provide a device, method, equipment and medium for assessing the operation health of rural domestic sewage treatment facilities to quantitatively evaluate the operation health status of rural domestic sewage treatment facilities.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: a device for assessing the operation health of rural domestic sewage treatment facilities, including a data access module, an operation health assessment calculation module, a data storage module, sensors, and a result output module;

[0007] The data access module receives data generated by a water quality sensor, a flow sensor, an equipment operation monitoring sensor, and an operation and maintenance arrival monitoring sensor, and conducts data inspection and update;

[0008] The operation health assessment calculation module calculates the operation health assessment index of rural sewage treatment facilities according to the accessed water quality, water volume, power equipment operation information, operation and maintenance arrival information, and basic configuration data according to the operation health assessment method for rural domestic sewage treatment facilities;

[0009] The data storage module stores the configuration data required for the operation health assessment and stores the calculated operation health assessment index data;

[0010] The sensors include water quality sensors, equipment operation monitoring sensors, flow sensors, and operation and maintenance arrival monitoring sensors;

[0011] The result output module is connected to the storage module and is used to output the result data of the analysis and evaluation.

[0012] The present invention also discloses a method for evaluating the operation health of rural domestic sewage treatment facilities, which includes the following steps:

[0013] S1. Data access, accessing and collecting data such as the operation status of power equipment, flow rate, water quality, and arrival of operation and maintenance personnel;

[0014] S2. Obtain the basic data of the treatment facility and calculate the configuration data, and determine the calculation period;

[0015] S3. According to the accessed data, calculate the facility load rate, pollutant removal rate, failure incidence rate, effluent compliance rate, and arrival completion rate;

[0016] S4. Calculate the operation health assessment result in combination with the configuration data;

[0017] S5. Store the intermediate data and result data of the operation health assessment.

[0018] Preferably, the calculation algorithm in step S3 is specifically as follows:

[0019] 3.1. The facility load rate is divided into holiday load rate and non-holiday load rate, specifically as follows:

[0020] Calculation method of facility holiday load rate:

[0021] Screen the holiday list within the calculation period. The screened holidays include weekend rest days and national legal holidays. If there are no holidays in the calculation period, there will be no result data NULL for this calculation. If there are holidays in the calculation period, calculate according to the influent flow rate within the calculation period and the designed daily treatment capacity of the facility. The formula is as follows:

[0022] [Facility holiday load rate] = [Average daily influent flow rate of the facility during holidays] / [Designed daily treatment capacity of the facility];

[0023] Calculation method of facility non-holiday load rate:

[0024] Screen the non-holiday list within the calculation period. If there are no non-holidays in the calculation period, there will be no result data NULL for this calculation. If there are non-holidays in the calculation period, calculate according to the influent flow rate within the calculation period and the designed daily treatment capacity of the facility. The formula is as follows:

[0025] [Facility non-holiday load factor] = [Average daily influent flow of the facility on non-holidays] / [Design daily treatment capacity of the facility];

[0026] 3.2. The calculation method of the pollutant removal rate of the facility is as follows. Data selection is based on monitoring data or manual detection data, but not both at the same time. Priority is given to influent and effluent monitoring data:

[0027] Calculation method of COD removal rate. The formula is:

[0028] [COD removal rate] = ([Influent COD] - [Effluent COD]) / [Influent COD];

[0029] Influent COD: Average value of the influent COD value monitored or detected in the calculation period. If the influent COD value < 30 mg / L, the COD removal rate is the null result data NULL;

[0030] Effluent COD: Average effluent COD value monitored or detected in the calculation period;

[0031] Calculation method of ammonia nitrogen removal rate. The formula is:

[0033] Influent ammonia nitrogen: Average value of the influent ammonia nitrogen value monitored or detected in the calculation period. If the influent ammonia nitrogen < 10 mg / L, the ammonia nitrogen removal rate is the null result data NULL;

[0034] Effluent ammonia nitrogen: Average effluent ammonia nitrogen value monitored or detected in the calculation period;

[0035] Calculation method of total phosphorus removal rate. The formula is:

[0036] [Total phosphorus removal rate] = ([Influent total phosphorus] - [Effluent total phosphorus]) / [Influent total phosphorus]

[0038] Effluent total phosphorus: Average effluent total phosphorus value monitored or detected in the calculation period;

[0039] Calculation method of suspended solids removal rate. The formula is:

[0040] [Suspended solids removal rate] = ([Influent suspended solids] - [Effluent suspended solids]) / [Influent suspended solids];

[0041] Inlet suspended solids: The average value of the inlet suspended solids measured or detected by the monitoring or detection facility during the calculation period. If the inlet suspended solids < 10 mg / L, the suspended solids removal rate is the null result data NULL;

[0042] Outlet suspended solids: The average value of the outlet suspended solids of the monitoring or detection facility during the calculation period;

[0043] 3.3. The calculation method of the facility failure incidence rate is as follows:

[0044] [Facility failure incidence rate] = [Number of hours of facility failures during the period] / [Number of hours during the calculation period];

[0045] In the above formula, [Number of hours of facility failures during the period] refers to the time when one or more failures occur and are not processed. If multiple failures occur at the same time, the failure durations are combined and calculated without accumulation;

[0046] 3.4. The calculation method of the facility effluent compliance rate is as follows:

[0047] [Facility effluent compliance rate] = [Number of times the facility effluent passes the detection during the period] / [Number of times the facility effluent is detected during the period];

[0048] If there is no facility effluent detection data during the calculation period, the compliance rate is the null result data NULL;

[0049] 3.5. The calculation method of the facility operation and maintenance arrival completion rate is as follows:

[0050] [Facility operation and maintenance arrival completion rate] = [Number of actual arrivals for facility operation and maintenance during the period] / [Number of scheduled arrivals for facility operation and maintenance during the period];

[0051] If the number of scheduled arrivals for facility operation and maintenance during the calculation period < 1, the completion rate is the null result data NULL.

[0053] Calculate the facility load rate evaluation index, pollutant removal rate evaluation index, failure incidence rate evaluation index, effluent compliance rate evaluation index and operation and maintenance arrival completion rate evaluation index based on the facility load rate, pollutant removal rate, failure incidence rate, effluent compliance rate and arrival completion rate. Calculate the facility operation health evaluation index based on each index. The specific formula is as follows:

[0054] [Facility operation health evaluation index] = [Facility load rate evaluation index] * [Facility load rate calculation weight] + [Pollutant removal rate evaluation index] * [Pollutant removal rate calculation weight] + [Failure incidence rate evaluation index] * [Failure incidence rate calculation weight] + [Effluent compliance rate evaluation index] * [Effluent compliance rate calculation weight] + [Operation and maintenance arrival completion rate evaluation index] * [Operation and maintenance arrival completion rate calculation weight].

[0074] Preferably, the full score of the pollutant removal rate evaluation index is 100 points, and the calculation method is as follows:

[0075] [Pollutant removal rate evaluation index] = [COD removal rate evaluation index] * [COD removal rate calculation weight] + [Ammonia nitrogen removal rate evaluation index] * [Ammonia nitrogen removal rate calculation weight] + [Total phosphorus removal rate evaluation index] * [Total phosphorus removal rate calculation weight] + [Suspended solid removal rate evaluation index] * [Suspended solid removal rate calculation weight];

[0076] The calculation of the sub-items in the above formula is as follows:

[0163] [1] The facility load rate is divided into the holiday load rate and the non-holiday load rate, and the load rate calculation method is:

[0164] 1) Calculation method for the facility's holiday load rate:

[0165] Screen the holiday list within the calculation period. The screened holidays include weekend rest days and national statutory holidays. If there are no holidays in the calculation period, the result data for this calculation is NULL. If there are holidays in the calculation period, calculate according to the influent flow rate and the designed daily treatment capacity of the facility during the calculation period. The formula is as follows:

[0166] [Facility holiday load rate] = [Average daily influent flow rate of the facility during holidays] / [Designed daily treatment capacity of the facility]

[0167] 2) Calculation method for the facility's non - holiday load rate:

[0168] Screen the non - holiday list within the calculation period. If there are no non - holidays in the calculation period, the result data for this calculation is NULL. If there are non - holidays in the calculation period, calculate according to the influent flow rate and the designed daily treatment capacity of the facility during the calculation period. The formula is as follows:

[0169] [Facility non - holiday load rate] = [Average daily influent flow rate of the facility during non - holidays] / [Designed daily treatment capacity of the facility]

[0170] [2] The calculation method for the facility's pollutant removal rate is as follows. The data can be selected according to the monitoring data or manual detection data, but not both at the same time. The influent and effluent monitoring data are preferred:

[0171] Calculation method for COD removal rate. The formula is:

[0172] [COD removal rate] = ([Influent COD] - [Effluent COD]) / [Influent COD]

[0173] Influent COD: The average value of the monitored or detected influent COD value of the facility during the calculation period. If the influent COD value < 30 mg / L, the COD removal rate is NULL, the result data.

If the suspended solids in the influent < 10 mg / L, the suspended solids removal rate is the null result data NULL.

[0186] Suspended solids in effluent: The average suspended solids value in the effluent of the monitoring or detection facility during the calculation period;

[0187] [3] The calculation method for the incidence rate of facility failures is:

[0188] [Incidence rate of facility failures] = [Number of hours of facility failures during the period] / [Number of hours during the calculation period]

[0189] In the above formula, [Number of hours of facility failures during the period] refers to the time when one or more failures occur and are not processed. If multiple failures occur at the same time, the failure durations are calculated together without accumulation.

[0190] [4] The calculation method for the compliance rate of facility effluent is:

[0191] [Compliance rate of facility effluent] = [Number of times of passing the effluent detection of the facility during the period] / [Number of times of effluent detection of the facility during the period]

[0192] If there is no effluent detection data of the facility during the calculation period, the compliance rate is the null result data NULL.

[0193] [5] The calculation method for the completion rate of facility operation and maintenance on-site is:

[0194] [Completion rate of facility operation and maintenance on-site] = [Number of actual on-site arrivals for facility operation and maintenance during the period] / [Number of scheduled on-site arrivals for facility operation and maintenance during the period]

[0195] If the number of scheduled on-site arrivals for facility operation and maintenance during the calculation period < 1, the completion rate is the null result data NULL.

[0197] Calculate the facility load rate evaluation index, pollutant removal rate evaluation index, failure incidence rate evaluation index, effluent compliance rate evaluation index, and operation and maintenance attendance completion rate evaluation index based on the facility load rate, pollutant removal rate, failure incidence rate, effluent compliance rate, and attendance completion rate. Calculate the facility operation health evaluation index based on each index. The specific formula is as follows:

[0198] [Facility operation health evaluation index] = [Facility load rate evaluation index] * [Facility load rate calculation weight] + [Pollutant removal rate evaluation index] * [Pollutant removal rate calculation weight] + [Failure incidence rate evaluation index] * [Failure incidence rate calculation weight] + [Effluent compliance rate evaluation index] * [Effluent compliance rate calculation weight] + [Operation and maintenance attendance completion rate evaluation index] * [Operation and maintenance attendance completion rate calculation weight]
