Embodiment 1

[0020] The invention utilizes a plant material adsorbent and a hydrophila organism to jointly remove heavy metal pollutants in a landscape water body. The present invention mainly designs a special device. The device is shown in Figure 1. The device includes a box body 1, a box body frame 2, a rigid nylon screen 3, a water silk worm fixed isolation net 4, and a fixed lock 5 And the foam plastic floating plate 6; the box body 1 is surrounded by the box body frame 2 and the rigid nylon screen 3 in between; the hole diameter of the rigid nylon screen is less than 0.5mm; the water silk worm fixed isolation screen 4 is located away from At one-third of the total height of the box at the bottom of the box, the aperture of the fixed isolation net is less than 0.7mm; the thickness of the fixed isolation net 4 and the nylon screen 3 is 0.3-0.4mm; set at the bottom of the box 1 There is a foamed plastic floating plate 6 to ensure that the top of the box 1 is suspended above the water surfac...

Abstract

The invention relates to a method for united removal heavy metal pollutants from landscape water body by plant material sorbent and a limnodrilus organism and a device thereof, belonging to the technical field of water body purification and environmental protection. The invention uses the plant material sorbent and the limnodrilus organism to unitedly remove the heavy metal pollutants from the landscape water body. The invention relates to a preparation process of the plant material sorbent and the limnodrilus organism and a special device for supplementary use, the special device is a tank body with a fixed separation net of the limnodrilus. The method comprises the following steps: putting the limnodrilus and the plant material sorbent on the fixed separation net in succession; suspending the tank body in the water body to be treated while the superface of the tank body is revealed from the water; supplementing the plant material sorbent into the tank body every 2-4 days while the processing period is 7-10 days. In the invention, the plant material sorbent after being absorbed heavy metal can be ingested by the limnodrilus, thus effectively improving biological effect of removal of the heavy metal from water body.

Description

Technical field [0001] The invention relates to a method and a device for the combined removal of heavy metal pollutants in landscape water by a plant material adsorbent and vermillion organisms, and belongs to the technical field of water purification and environmental protection. Background technique [0002] Since the 20th century, with the rapid development of industry and economy, various countries in the world have encountered environmental pollution problems of varying degrees. Among them, industrial "three wastes" emissions, agricultural activities, and urban non-point source pollution have caused landscape water bodies to suffer from organic, inorganic and organic pollution. The main cause of heavy metal pollution. The concentration of heavy metal pollutants in the water body is relatively low compared to the large amount of nutrients such as nitrogen and phosphorus in the eutrophic water body. However, once these heavy metal pollutants enter the water body, they may cau...
