Water pollution survey report

I. Reasons for investigation With the development of science, the progress of the times, and the rapid growth of the population, the environment on which human beings depend for survival and development is polluted, the ecological environment is destroyed, and the ecosystem is also destroyed. Environmental problems have been removed from the region. Sexuality goes global, and human beings must care for the earth and care about and solve global environmental problems. Because we "have only one earth."
Water is the source of life. Without water, our lives will not continue. The pollution and shortage of water resources is a major problem facing today's society. Although the city is not a city with water stress, water pollution exists and is closely related to every citizen. To this end, I investigated the water pollution in our city through inquiry.
Second, the investigation process The first step: field investigation, first of all, I came to Chang'an Air Traffic Control Station with my dad, and learned from my dad's old classmate Liu Haihua about the river course in Chang'an Town. Then, I took a speedboat and visited Chongchang Port and Chang. Shanhe and Taishan Port, along the way, Uncle Liu Haihua introduced me to these rivers decades ago. These rivers are the main waterways near Chang'an Town. The water is clear and clear, and now the garbage is all over the river, and a smell comes from the nose. Main causes of water pollution: human factors: wastewater discharge from the upper reaches of the Nihe River, urban sewage sewers are placed here, sewage is discharged into the river through the passage, a large amount of farmland near the mud river, chemical substances such as fertilizers and pesticides used by farmers flow into it, causing algae The madness is long, the fish are dying in large numbers, and the residents have poor environmental awareness, and often dump the domestic garbage into the river.
The second step: investigation and analysis, after field investigation, I think the harm caused by water pollution to residents. Groundwater pollution, water use is difficult, river water pollution is serious to breed a large number of mosquitoes, river water emits irritating odor, which has an adverse impact on people's health.
III. Investigation conclusions In order to improve the river environment, all aspects of river and riverbank management should be carried out as soon as possible. First of all, the pollution source should be treated to prevent the sewage and manure from being directly discharged into the river by factories and pig farms, and should be treated in a centralized manner to avoid adverse effects on the environment. Then, the building materials in the rivers and rivers will be cleared, and the waterways will be rectified to further remove the garbage and silt in the river, which will mobilize coastal residents and use large machines to remove them. After planting trees at the riverside, planting turf and establishing green belts to avoid sand loss.
2. In order to ensure the protection of the river environment, the management of nearby factories and pig farms should be strengthened, the behavior of polluted rivers should be dealt with seriously, and environmental protection education should be carried out for coastal residents and all citizens to enhance environmental awareness. The environment is mainly based on the ideology of everyone, so people should consciously protect the river and protect the environment. In this way, a new river will always be presented to the people.

In short, it is necessary to clarify that the environment is destroyed and the people themselves are affected. We should fully understand the relationship between the environment and human beings and fully recognize the advantages and disadvantages of people changing the environment. The factors affecting water resources are far more than these. Although our research may not be mature enough, we hope to improve the status of environmental issues and water pollution in people's minds, so that problems will improve day by day.
