Description
Technical Field
The invention relates to the technical field of water body remediation, in particular to a water body pollution sediment floating and sinking type in-situ remediation method.
Background
The polluted bottom mud is an important endogenous pollution source of the urban river water body and is one of the important reasons for blackening and smelling the water body. While effectively intercepting and controlling the input of the exogenous pollutants, the treatment measures aiming at the endogenous pollution of the sediment are required to be adopted. Commonly used remediation methods include physical, chemical and bio-ecological methods. The physical method mainly comprises dredging, artificial reoxygenation, water diversion and flowing water and the like. The chemical method mainly comprises reinforced flocculation, chemical oxidation and the like. The biological ecological method mainly comprises in-situ injection of biochemical agents, addition of microbial agents, addition of growth promoting agents, plant purification technology and the like. The ectopic treatment measures such as dredging and dredging have higher cost, complex process and large difficulty in large-scale implementation in a short time, and easily cause the release and transfer of bottom mud pollutants to form secondary pollution. In the in-situ treatment measures, the method for injecting the biochemical medicament in situ directly aims at the generation process of the black and odor causing substances in the sediment, has a good black and odor eliminating effect, and has attracted wide attention in recent years.
The method of injecting biochemical agents in situ promotes microorganisms to degrade and convert organic pollutants by injecting electron acceptors (such as nitrate) with higher oxidation-reduction potential (ORP) into the polluted sludge layer in a directional way, so that sulfides (typical black-making odor-causing substances) generated in the reduction process of the electron acceptors (such as sulfate) with lower ORP are inhibited, and the reduction of organic matters and the content of the remaining sulfides in the bottom sludge can be realized. The polluted bottom mud is restored by adopting a mode of injecting calcium nitrate in the Japanese pipa lake and the town gate river in the hong Kong area of China, and the result shows that the removal rate of sulfides exceeds 90 percent, the odor is basically eliminated, and the bottom mud is changed from black to gray.
In the engineering case of normal position injection biochemical agent restoration, liquid biochemical agent solution is more adopted, the medicament solution of certain concentration is directional to be injected to the target mud layer degree of depth, but the construction degree of difficulty is great, rely on the self diffusion and infiltration effect of medicament, not only repair time is long, the phenomenon that partial medicament floats up to the water body appears easily still, simultaneously because the pollution condition of bed mud is inconsistent, hardly effectively carry out the restoration of pertinence to the pollution degree, lead to current repair effect relatively poor, efficiency is lower.
