As we all know, we are now in the age of population explosion. More people need more food. Growing food and vegetables requires more and more water resources. At the same time, clean water resources are increasingly limited. What should we do? Some people come up with an idea that why don't use treated wastewater to water vegetable fields.

Some wastewater may be used directly without treatment, such as beer wastewater. In theory, beer wastewater not only contains no toxic substances but also contains many organic substances and nutrients needed by plant growth.

Near a brewery in Shandong, researchers set up three experimental fields: clear water irrigation area, wastewater irrigation area, and mixed irrigation area of clear water and wastewater. They planted six crops: leek, green onion, pakchoi, lettuce, potato, and cabbage.

In the harvest season, the researchers examined the contents of vitamin C, nitrate, and nitrite in crops in three experimental fields and found that irrigation with beer wastewater can significantly increase the content of vitamin C in lettuce, potato, and cabbage. This seems to be good news. On the other hand, wastewater increased nitrate content in pakchoi, lettuce, and cabbage and increased nitrite content in leek and potato. Only green onions have not been significantly affected.

Generally speaking, it is very difficult for human beings to bypass the production mode of wastewater as agricultural water after treatment. Many research findings show that reclaimed water irrigation has both advantages and disadvantages, which cannot be generalized simply. The key problem is how to treat the effluent wastewater and whether the treated reclaimed water can meet the irrigation standard. Shenyang, Tianjin, and other cities in China have suffered from heavy metal pollution caused by effluent wastewater irrigation. Using untreated or substandard agricultural water rich in pollutants is tantamount to quenching thirst with poison. Examples show that only when properly treated, reclaimed water can slightly relieve the pressure on water resources on the premise of ensuring human health.
