Turf laying device for treating polluted land based on environmental protection engineering

Abstract

The invention relates to the technical field of polluted land treatment, in particular to a turf laying device for treating polluted land based on environmental protection engineering. The turf laying device for treating polluted land based on environmental protection engineering comprises a device main body, the device main body comprises a bottom layer soil collecting cover, one side of the bottom layer soil collecting cover is fixedly provided with a counterweight seat, two surfaces of the counterweight seat are sleeved with antiskid rollers through rotating shafts, and a partition plate is fixedly arranged on an inner wall of the bottom layer soil collecting cover. By arranging the bottom layer soil collecting cover, a top layer soil collecting cover, the partition plate, a bottom layer soil shoveling plate and a top layer soil shoveling plate, the lowest point of the bottom layer soil shoveling plate is lower than the lowest point of the top layer soil shoveling plate, such that the top layer soil shoveling plate shovels soil on a surface layer into the top layer soil collecting cover. Soil on a middle layer is mixed into the bottom layer soil collecting cover by utilizing the bottom layer soil shoveling plate, such that the soil on the surface layer can be removed when the device is used for turning the soil, the excessive heavy metal content in a laying layer is avoided, and a survival rate of the newly-laid turf is higher.

Description

technical field [0001] The invention relates to the technical field of polluted land treatment, in particular to a turf laying device for polluted land treatment based on environmental engineering. Background technique [0002] Soil pollution prevention and control is the activity of preventing soil from being polluted and improving and remediating polluted soil. Soil protection should focus on prevention. The focus of prevention should be on controlling the concentration and total amount of emissions from various pollution sources; regular monitoring and supervision of agricultural water use to make it meet the water quality standards for farmland irrigation; rational use of chemical fertilizers and pesticides, and prudent use of sewage sludge and river mud , Pond mud; urban sewage irrigation must be purified; promote biological control and comprehensive control of pests and weeds, and remediate mines to prevent mine pollution. [0003] When dealing with soil pollution, t...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of turf laying device based on environmental protection engineering for polluted land treatment, to solve the problem that when laying turf at present in the above-mentioned background technology, generally all is to carry out turf laying after digging first, and the surface soil Perennial sunshine makes the soil dry, and the heavy metal pollutants in it are difficult to sink without water as a carrier. Although the direct turning of the soil will dilute the heavy metal pollutants in the surface layer, the heavy metal pollutants in the grass paved layer are still relatively low. Among them, if the content of manganese and lead is too much, it will make it difficult for the newly laid turf to grow and take root, which will lead to excessive death of grass seedlings, making the follow-up purification effect not ideal.
