Study On The Influence Of Wastewater Irrigation On Agricultural Environment And Productes Quality In Hebei Province

In this paper, the impact of the use of wastewater in Hebei agriculturalproduction on the environment for the growth of food crops is studied. Through thecollection and collation of data, focusing on activities such as testing thecontaminated areas, investigate comprehensively the cultivation of food crops, the useof wastewater in Hebei province, analyze the impact of the use of wastewater underdifferent irrigation conditions on the groundwater, soil conditions and quality of foodcrops and the extent. The results showed that: 1) Wastewater Irrigation contaminantsin shallow groundwater levels were higher than the irrigation district, COD, phenol,NO₃^--N and NO₂^--N as the main discharge of pollutants. 2) The typical wastewaterirrigation chromium, mercury, cadmium, lead and arsenic in soil has different levelsof accumulation. Cadmium soil environmental quality standards that exceed the statestandards and green food production in the secondary soil environmental qualitystandards. 3) The existence of different levels of heavy metals in wastewater irrigationdistrict crops. Reasonable wastewater irrigation on crop yield significantly, anincrease in the rate of more than 10ï¼…. Papers also predict the impact of the use ofwastewater on agriculture environment and that will provide a technical basis toregional production quality and safety of agricultural products.
