A repair system and repair method for heavily organically polluted surface water

Abstract

The invention provides a restoration system and restoration method used for severely organically polluted surface water. The restoration system comprises a water collecting system, a water treatment system, a slow-release oxidation and filtration system and an ecological restoration system, which are connected with each other in order, wherein the water collecting system comprises a water pump; water is pumped into an overland middle pool by the water pump; the middle pool serves as a regulating reservoir for water to enter the water treatment system; the water treatment system is a Fenton advanced oxidation treatment system; the slow-release oxidation and filtration system adopts a PVC pipeline filled with slow-release oxidation materials and filter materials; the ecological restoration system comprises an overland ecological system and an overwater ecological system. The restoration system and the restoration method have the advantages that organic pollutants in water are removed by the Fenton advanced oxidation technology, the water quality conditions are improved through slow-release oxidation and filtration, a water body and a peripheral ecological system are constructed through ecological restoration, and part of the treated water up to the standard is used for irrigation of the ecological systems in control regions and part of the treated water up to the standard feeds into the surface water body, thus combining restoration by the physio-chemical technology with restoration by the ecological technology and efficiently and thoroughly completing restoration and control of the polluted surface water.

Description

technical field [0001] The invention belongs to the technical field of water pollution restoration, and in particular relates to a restoration system and restoration method for heavily organically polluted surface water. Background technique [0002] The rapid development of the industrial economy has also brought many environmental pollution incidents. The leakage and illegal discharge of industrial products, waste materials, waste liquids, etc. have occurred frequently, resulting in serious pollution of surface water and even groundwater. Waste liquid with high concentration of organic pollutants has been discharged into surface waters for a long time. Its characteristics of high toxicity, irritating odor and refractory degradation have caused serious threats to residents' health, ecological environment and social stability. The treatment of organic polluted surface water is urgent. The treatment of heavily polluted surface water is challenging. The reason is that the conc...

[0002] The rapid development of the industrial economy has also brought many environmental pollution incidents. The leakage and illegal discharge of industrial products, waste materials, waste liquids, etc. have occurred frequently, resulting in serious pollution of surface water and even groundwater. Waste liquid with a high concentration of organic pollutants has been discharged into surface waters for a long time. Its characteristics of high toxicity, irritating odor and refractory degradation have caused serious threats to residents' health, ecological environment and social stability. The treatment of organic polluted surface water is urgent

The treatment of heavily polluted surface water is challenging. The reason is that the concentration of severe organic pollutants is high, and the treatment itself is difficult. Moreover, the surface water area is open and the water volume is large. Long-term pollution has caused difficulties to the water environment and the surrounding ecological environment. Therefore, the design of a three-dimensional restoration system suitable for the restoration of heavily organically polluted surface water, the use of various treatment technologies, and the restoration idea of ​​combining pollution elimination and environmental improvement will be the leading direction for future restoration of polluted environments
