What the data for this category looks like
Data for this category comes primarily from public water quality monitoring station data released by ecological environment departments, internal operation and maintenance systems of water utility operators, and official reports from third-party testing institutions. Three update cadences apply:
- Real-time water quality parameters are synced every hour
- Daily operation and maintenance logs are archived daily
- Compliance testing reports are updated per project cycle or quarterly
Each due diligence report has a fixed six-chapter structure: project overview, core water quality indicators, process operation data, compliance test results, operation and maintenance anomaly records, and rectification suggestions. Core fields include COD concentration, total nitrogen concentration, treatment scale, and sludge moisture content. Concentration-type parameters use mg/L as their unit, treatment scale uses cubic meters per day, and moisture content is recorded as a decimal.
What constraints these characteristics impose on tool calling and plugins
The hourly update cadence for real-time water quality parameters requires tool calling to be configured with scheduled pull tasks. Cached data older than one hour must not be used to ensure report timeliness.
Fixed units for core fields require plugins to include built-in parameter validation logic. This logic checks for unit matching on incoming concentration and scale parameters to prevent data misuse.
The fixed document structure requires tool calling to extract content in the preset chapter order. This avoids field misalignment caused by cross-chapter scraping.
The need to process batch compliance reports requires plugins to support parallel parsing of multiple files, and adapt to format differences across report sources.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Water treatment due diligence reports often include multiple pages of test reports and operation logs, with individual files up to 500 MB, covering common scenarios |
TOOL_CALL_TIMEOUT | 300 seconds | Pulling water treatment data and parsing reports takes significant time; 300 seconds covers the parsing process for most compliance reports |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Text parsing of individual water treatment reports requires processing large amounts of tabular data; 120 seconds enables complete parsing |
MCP_TOOL_RETRY_COUNT | 3 retries | Network fluctuations or temporary unavailability of third-party data sources; 3 retries reduces the impact of temporary failures |
WORKFLOW_VAR_ENABLE_UPLOAD | Enabled | Required to support binding workflow variables to upload parameters, adapting to dynamic file invocation scenarios |
TOOL_PARAM_VALIDATE_MODE | Strict unit matching | Water treatment data fields must strictly match units such as mg/L and cubic meters per day to avoid data errors |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: A
504 Gateway Timeouterror is returned when calling an MCP tool, or a "tool call failed" prompt appears. Cause: TheMCP_TOOL_RETRY_COUNTparameter is not configured, or the retry count is set to 0, failing to cover temporary network fluctuations or data source delay scenarios. - Phenomenon: An "File size exceeds limit" prompt appears when uploading a water treatment test report, and the log shows
File size exceeds 2097152 bytes. Cause: TheUPLOAD_FILE_MAX_SIZEconfiguration item is not modified, and the default 2 MB limit is retained, which cannot adapt to individual large test reports. - Phenomenon: When configuring upload file parameters in a custom workflow, workflow variables cannot be selected as the upload source, and only file links are supported for input. Cause: The
WORKFLOW_VAR_ENABLE_UPLOADconfiguration item is not enabled, and the system does not enable the function to bind variables to upload parameters.
How to Confirm Configuration is Complete
- Upload a test file that conforms to the water treatment due diligence report format, check the upload progress and results, and confirm that the file upload process works normally.
- Call an MCP tool to pull real-time water quality data, wait for the configured timeout period, and check the returned results to confirm that no timeout errors occur.
- Configure upload parameters in a custom workflow, attempt to bind a workflow variable as the upload source, and confirm that variable options can be normally selected and invoked.
- Call a tool with water treatment parameters that include units, check whether the tool's returned results correctly validate the parameter format and units.
