《GB/T 16811-2018工业锅炉水处理设施运行效果与监测》由TC262（全国锅炉压力容器标准化技术委员会）归口，TC262SC7（全国锅炉压力容器标准化技术委员会锅炉传热介质分会）执行，主管部门为国家标准化管理委员会。
Introduction
Analysis of the core content of the standard
| Technical module | New content in the 2018 version | Changes in detection indicators | Strengthening management requirements |
|---|---|---|---|
| Pretreatment equipment | Add the requirement of SDI≤5 for reverse osmosis influent | Turbidity index is refined to 0.1FTU | Mandatory online monitoring configuration |
| Ion exchange equipment | New weak acid resin detection method | Working exchange capacity increased by 15% | Annual consumption rate≤7% |
| Reverse osmosis equipment | Add inter-stage pressure difference monitoring | Desalination rate drop rate ≤10% | Safety interlock mandatory requirement |
Detailed explanation of key technical indicators
Case 1: A 4t/h steam boiler uses a two-stage sodium ion exchanger. Testing found that the actual utilization rate of the resin was only 48% (the standard requirement is ≥55%). By optimizing the regeneration agent concentration and flow rate, it was increased to 62% three months later. Calculation formula: η=(Q×A)/(VR×Eq)×100%
Key points for standard implementation
- Establish a double-check system for water quality monitoring to ensure data accuracy
- Performance evaluation of reverse osmosis membrane elements every quarter (ΔY≤10%)
- Verification of antiscalant effect requires simulation of 8-fold concentration conditions
Solutions to common problems
| Problem phenomenon | Standard basis | Handling measures |
|---|---|---|
| Frequently exceeding pH value of boiler water | Clause 7.1.4.2 | Check the metering accuracy of the dosing device (±10%) |
| Annual resin consumption exceeds 15% | Table 3 Note 2 | Evaluate the purity of the regeneration agent (NaCl≥98%) |
