Remediation and Prevention Strategies for Water Source Pollution of Forest Land in Nature Reserves
Water source pollution of forest land is related to the survival and development of organisms in the whole nature reserve.In order to protect water quality,it is important to study water source pollution remediation and prevention strategies.Taking a water source in a natural reserve as an example,the raw water required for the test was collected,and four water quality analysis items and corresponding detection methods were determined based on the selection of test reagents and equipment.For the raw water,the wa-ter source was first repaired by chitosan microspheres+active infiltration reaction wall,and in-situ bacte-rial injection technology,and then the pollution prevention was realized by artificial wetlands and artificial oxygen enrichment.The results showed that after the implementation of the remediation strategy,the per-formance of various water quality indicators became better,the number of plankton and chlorophyll a con-tent in the forest water source gradually increased,the comprehensive pollution index of heavy metals and permanganate index gradually decreased,and the remediation strategy had played a due purification effect;after the implementation of the prevention and control strategy,the performance of the four water quality indicators continued to improve in the first 1-3 days,then decreased slightly and finally main-tained at a relatively stable level,indicating that the prevention and control strategy basically maintained the implementation effect of the remediation strategy and played a due role in prevention and control.
