According to the repair precision and the lower limit value of 70.8g, the dosage of the drug for repairing trichloroethylene every time is 23.6g (the dosage operation reaches the lower limit value of 70.8g for 3 times), four sleeves are selected to prepare a plurality of drug packages, and the dosage of each drug package is 23.6/4g, then:
1. controlling a dosing device to carry out dosing operation for 3 times, wherein each sleeve releases a medicament package in each dosing operation, the dosing device comprises 4 sleeves, and the dose of the dosed medicament reaches the lower limit value of the dose required by trichloroethylene repair;
2. reacting for a certain time, and detecting that the concentration of trichloroethylene is 12 mg/L and the target of remediation is not reached (the IV-class water standard of underground water is less than or equal to 210 mu g/L);
3. controlling a dosing device to carry out 1 dosing operation, reacting for a certain time, and detecting that the concentration of trichloroethylene is XXmg/L, so that the repair target is not reached;
4. and (5) circularly executing the step 3 until the repairing target is reached.
Therefore, the repair target can be achieved, the overdose amount is greatly reduced, the maximum overdose amount of the medicament in the embodiment is not more than 23.6g, the adjustment can be carried out according to the repair precision requirement, the control precision of the overdose amount is greatly improved, and the problem of overdose amount of the medicament is avoided.
According to the groundwater water quality detection and restoration method, the lower limit value of the medicament amount required by water quality restoration is obtained according to the pollutant components and the pollutant concentration of each component, the medicament amount and the minimum medicament adding frequency of each medicament adding are obtained according to the lower limit value and the restoration precision, and the medicament adding operation with the minimum medicament adding frequency is completed firstly under the condition of no detection, so that the detection frequency is reduced, the restoration efficiency is improved, the excessive medicament adding can be avoided, and the medicament adding operation is performed once per detection until the restoration requirement is met or the restoration requirement is smaller than the set concentration value.
