  • Publication number: 20250178050
    Abstract: The present disclosure provides an in-situ electric stratified remediation device and method for accurate position in remediation depth in sediment. the device includes a telescopic rod, a porous cylinder, a water storage tank, a curing agent storage device, and a depth determining module. The water storage tank is configured to collect sediment pore water and contaminants converged along a surface groove of a columnar electrode; and the fixed determining module is configured to send an indication information in response to that the curing agent storage device is inserted below a mud-water interface, while triggering release of curing agent from a wall of the curing agent shroud.

  • Patent number: 12286371
    Abstract: An emergency treatment device for algal blooms in reservoir tributaries and bays includes a hull, an automatic detection unit provided on the hull, an algae collection-separation unit, an ultrasonic algae removal unit, a micro-current electrolytic algae suppression unit, an algaecide adding unit, a power unit and a control unit. The automatic detection unit, the algae collection-separation unit, the ultrasonic algae removal unit, the micro-current electrolytic algae suppression unit, the algaecide adding unit and the power unit are connected with the control unit. The algae collection-separation unit is used for suction and ex-situ treatment of high-density algae on a surface of the water body. The ultrasonic algae removal unit, the micro-current electrolytic algae suppression unit and the algaecide adding unit are used for in-situ treatment of algae in the water body.
