Heavy metal removal equipment for irrigation water in agricultural greenhouse and use method of heavy metal removal equipment

Abstract

The invention relates to the technical field of agricultural planting, in particular to heavy metal removal equipment for irrigation water in an agricultural greenhouse. The equipment comprises a base and a support frame, the support frame is positioned above the base, a circulating water pump is mounted above the base, and a water outlet is formed in the upper end of the circulating water pump. The water can flow into a circulation pipe 1 from the outlet of the circulating water pump to ensure the smoothness of the circulating water pump. A storage box is arranged above a mixing pipe, a plurality of supporting columns are welded to the bottom of the storage box, a discharging pipe is arranged among the supporting columns, and a transfer pipe is fixedly connected to the end, away from the storage box, of the discharging pipe. The iron salt in the storage box can enter the mixing pipe to be mixed with untreated water under the condition that water flows, the contact area of the untreated water and the iron salt is enlarged, the untreated water and the iron salt can make full contact, and the untreated water and the iron salt are guaranteed to be mixed more thoroughly, so that the reaction between the untreated water and the iron salt is quick and sufficient.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a heavy metal removal device for irrigation water in an agricultural greenhouse and a method for using the same. Background technique [0002] Heavy metals refer to metals with a density greater than 4.5g / cm3, including gold, silver, copper, iron, mercury, lead, cadmium, etc. Heavy metals are very difficult to be biodegraded, and heavy metals can strongly interact with proteins and enzymes in the human body. They may also be accumulated in some organs of the human body, causing chronic poisoning. If the irrigation water of agricultural planting species is not treated today, there will also be problems of excessive heavy metals. Heavy metals in irrigation water in agricultural greenhouses Removal has become an unavoidable topic at present, so heavy metal removal equipment for irrigation water in agricultural greenhouses is becoming more and more widely used.

AI Technical Summary

Problems solved by technology

[0003] However, the current heavy metal removal equipment for irrigation water in agricultural greenhouses also has defects. The current heavy metal removal equipment for irrigation water in agricultural greenhouses takes up a lot of space, and the heavy metal removal equipment for irrigation water in large agricultural greenhouses is bulky. The efficiency of water treatment is relatively slow. The current heavy metal removal equipment for irrigation water in agricultural greenhouses still has a large amount of precipitated impurities after removing heavy metals, and the water quality is not pure enough. After that, it needs to be disassembled and cleaned, which will cause great damage to the equipment, and the life of the equipment will be shortened during the disassembly and cleaning process.
