Device for monitoring low-concentration toxic reclaimed water

Abstract

The invention discloses a device for monitoring low-concentration toxic reclaimed water. The device comprises a vertical cabinet body, the vertical cabinet body comprises an upper cabinet body and a lower cabinet body, and an electrical control device and an image processing server are arranged in the upper cabinet body; a CCD camera is arranged at the top of the lower cabinet body, a double-circulation water tank for testing is arranged below the CCD camera, the double-circulation water tank comprises a tank body, and the interior of the tank body is divided into a left test tank and a right test tank which are the same in structure by a partition plate; the interior of the test tank is divided into a shooting monitoring area and an accessory area which are communicated with each other by a pore plate; a drainage pipe is arranged in the center of the shooting monitoring area; and the CCD camera is located over the center of the connecting line of the drainage pipes in the left shooting monitoring area and the right shooting monitoring area, the CCD camera is connected with the image processing server, and the device for monitoring the low-concentration toxic reclaimed water is reasonable in structure, small in occupied area, capable of conducting comparison monitoring, suitable for fish survival, few in interference factor and accurate in monitoring result.

Description

technical field [0001] The invention relates to the field of monitoring low-concentration toxic regenerated water, in particular to a device for monitoring low-concentration toxic regenerated water. Background technique [0002] The existing biological monitoring technology is mainly based on the luminescent bacteria method and the fish method. In 2020, our company applied for the patent CN111398550A, a biological monitoring method suitable for low-concentration toxic reclaimed water. The behavioral state of killifish, so as to judge whether the fish is alive, its activity and some abnormal states of the fish, and then monitor the toxicity of the water body; the patent discloses that this monitoring method needs to use CCD cameras, tanks and other equipment, but there is a lack of equipment that can realize this. The equipment of the method, common sink or fish tank can certainly be used, but also has certain defectives: [0003] First: Ordinary tanks or fish tanks cannot b...

[0002] The existing biological monitoring technology is mainly based on the luminescent bacteria method and the fish method. In 2020, our company applied for the patent CN111398550A, a biological monitoring method suitable for low-concentration toxic reclaimed water. The behavioral state of killifish, so as to judge whether the fish is alive, its activity, and some abnormal states of the fish, and then monitor the toxicity of the water body; the patent discloses that this monitoring method needs to use CCD cameras, water tanks and other equipment, but there is a lack of equipment that can realize this. The equipment of the method, common sink or fish tank can certainly be used, but also has certain defectives:

[0003] First: Ordinary tanks or fish tanks cannot be compared and monitored;

[0004] Second: Ordinary tanks or fish tanks are not suitable for fish survival due to limited conditions. There will be many interference factors that will cause fish to die, such as: lack of oxygen, low temperature, etc., so the accuracy of the monitoring results cannot be guaranteed
