Description

Heavy metal removing equipment for farmland irrigation

Technical Field

The invention relates to the field of farmland irrigation, in particular to heavy metal removing equipment for farmland irrigation.

Background

Along with the development of industry and the continuous improvement of urbanization degree, water resources are increasingly short, nearly 80% of cities in China have water shortage, the north is particularly serious, and the total water shortage in China reaches 1200 hundred million m every year³Therefore, the industrial output value is influenced by more than 2000 billion yuan each year. The shortage of water resource makes the sewage become an important component of irrigation water. At present, the sewage treatment rate in China is low, and the irrigation water quality seriously exceeds the standard. A large amount of heavy metal elements contained in the sewage can be enriched and dispersed in the soil, and the sewage is difficult to degrade, has strong toxicity and has the characteristic of accumulation effect. This makes the problem of heavy metal pollution of soil increasingly prominent. Researches prove that the heavy metal elements exceeding a certain limit can inhibit the growth of crops such as wheat, rice, corn and the like, thereby reducing the yield. And the absorption and accumulation of heavy metals in most crops are significantly related to the concentration of the heavy metals in the soil. Heavy metals can be harmful to human health through various food chain forms. The famous Japanese "bone pain" event is caused by the increase of cadmium content in soil and rice due to the irrigation of farmlands with wastewater from smelteries for a long time, and people eat the rice. Soil is an important link in a food chain and is one of the elements of the environment, so that the research on the problem of heavy metal pollution caused by sewage irrigation is of great significance for protecting the ecological environment and promoting the sustainable development of social economy.
