River and lake daily operation and maintenance and emergency response

Solution Overview  

River and lake health management should follow the principle of “30% treatment and 70% maintenance”, constructing a long-term maintenance system of “prevention first and combination of prevention and treatment”. Based on traditional maintenance (ecological regulation, facility maintenance, emergency management, etc.), our company integrates intelligent monitoring and intelligent decision-making technology to form an “air-ground-cloud” collaborative management model, realizing closed-loop management of “monitoring-early warning-handling-evaluation”. This system can reduce maintenance costs, improve emergency response efficiency, promote the transformation of river and lake management from passive treatment to active prevention and control, and ensure the long-term health of the water ecosystem.

Basic Principle

Solution

Ultra-nanometer reoxygenation improves the sediment environment and inhibits sediment release

High-concentration oxygen is dissolved in water in a supersaturated form without producing bubbles, and then this high-oxygen water is massively delivered directly above the most severely hypoxic sediment in the water body, covering the sediment with a layer of water with extremely high oxygen content. Coupling biogeochemical processes, improving the distribution of microbial flora in the water body and sediment, accelerating the degradation of organic pollutants in the water body, blocking the path of organic matter, nitrogen, phosphorus, harmful metals and other pollutants from the sediment to the water, controlling endogenous pollution, and effectively reducing pollutants such as COD, BOD, ammonia nitrogen, total nitrogen, total phosphorus, and harmful metals.

Adding highly efficient microbial agents to accelerate the degradation of organic matter

In areas with severe sediment pollution, highly efficient microbial agents are added to degrade the sediment in advance. Under aerobic conditions, the activity of indigenous microbial flora is induced to recover, achieving its own growth and reproduction, while achieving aerobic degradation of sludge, achieving the inorganic, reduction, and fixation of sludge.

Advantages of the Scheme

1. Does not destroy the original habitat, maximizing the preservation of biodiversity.

2. No dredging is required, and it does not affect the lives of nearby residents.

3. Compared with dredging projects, the overall project volume and cost are reduced by more than 50%, and secondary pollution of dredged sediment is also avoided.
