Problems solved by technology

The existing dosing device cannot control the dosage of the medicine well, which may easily lead to excessive dosage of the medicine and increase the repair cost
However, the existing groundwater detection and restoration integrated device is not designed with strong connectivity, low degree of automation, low accuracy, high cost, and requires a lot of manpower and material resources, so it cannot meet the requirements of sustainable social and economic development.

Embodiment 1

[0042] Such as figure 1 and 2 As shown, a groundwater quality detection and repair system provided by the present invention includes a monitoring pool 1, a repair pool 13, a first pollutant sensor 3, a second pollutant sensor 12, a water level detection sensor 2, a control device 5, and a driving device And the dosing device; the first pollutant sensor 3 and the second pollutant sensor 12 are respectively arranged in the monitoring pool 1 and the repairing pool 13; the dosing device 11 is fixedly arranged in the repairing pool 13; The device 11 is connected; the first pollutant sensor 3, the second pollutant sensor 12, the water level detection sensor 2, and the control end of the driving device are respectively electrically connected to the control device 5; under the control of the control device 5, the driving device drives the dosing The sleeve pipe 19 in the device 11 moves up and down. In this embodiment, the monitoring and repairing pool includes a monitoring pool 1 a...

Embodiment 2

[0055] The present invention provides a method for detecting and repairing groundwater quality, which is applied to a system for detecting and repairing groundwater quality as described in Embodiment 1, comprising:

[0056] 1. The water level detection sensor 2 detects the water level of the monitoring pool 1. When the water level reaches the set height, the indicator light corresponding to the water level detection sensor 2 lights up, and the single-chip microcomputer sends an instruction to the first pollutant sensor 3 according to the water level detection signal to start the first pollution. The detection action of the object sensor 3. The volume of water in the monitoring pool 1 can be obtained through the water level detection sensor 2 .

[0057] 2. The first pollutant sensor 3 detects the components of the water pollutants in the monitoring pool 1 and the concentration of each component pollutant.

[0058]The first pollutant sensor 3 detects that the water pollutants i...

Embodiment 3

[0071] Take the initial initial concentration of trichlorethylene: 0.15mmol / L, that is, 20 mg / L as an example, the volume of polluted water (remediation pool volume): 100 L, and the remediation agent: ferric sulfate + calcium oxide combination agent. The dosage needed to repair 20 mg / L trichlorethylene is 70.8g-283.2g. According to the repair accuracy and the lower limit value of 70.8 g, the dose of each dosing of trichlorethylene is 23.6 g (3 dosing operations reach the lower limit value of 70.8 g), and four casings are selected to make multiple drugs package, the dosage of each medicament package is 23.6 / 4g, then:

[0072] 1. Control the dosing device to perform 3 times of dosing operations. Each time the dosing operation releases a medicine package from each sleeve, the dosing device has 4 sleeves, and the dosing dose reaches the required dose for repairing trichlorethylene lower limit value;

[0073] 2. After reacting for a certain period of time, the concentration of tr...

Abstract

The invention discloses an underground water quality detecting and repairing system and method, wherein a pollutant sensor is adopted to detect and monitor the components and concentration of underground water pollutants in a restoration pool, and the dosage and dosing frequency of each dosing of a dosing device are strictly controlled according to the components and concentration, so that the restoration efficiency is improved, the dosing precision of a medicament is greatly improved, and excessive dosing of the medicament is avoided. According to the invention, the system is of a detecting and repairing integrated structure, manual participation is not needed in the whole detecting and repairing process, the intelligent degree is high, the control accuracy of the feeding amount is high,excessive feeding of chemicals can be avoided through the design of the chemical feeding device, the repairing cost is reduced, and the repairing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of pollution detection and repair, and in particular relates to an integrated automatic system and method for groundwater in-situ / ex-situ water quality detection and repair. Background technique [0002] Groundwater is an important part of the water environment system and a precious freshwater resource that can be provided to human beings. It is mainly formed by the direct infiltration of atmospheric precipitation and the infiltration of surface water into the ground. However, with the growth of the global population and the acceleration of urbanization and industrialization, the demand for groundwater resources has increased significantly, and problems such as water pollution and waste have become increasingly serious. If they deteriorate further, they will seriously threaten the stability of the ecological environment and human well-being. life safety. [0003] A common water resource pollution remediatio...
