Embodiment Construction

[0015] The method for enrichment, adsorption, and coupling treatment of arsenic-polluted water bodies of the present invention is firstly to make several figure 2 As shown in the processing unit, the manufacturing process of the processing unit includes the following steps:

[0016] a. select the moso bamboo 1 with a diameter of 15cm-20cm, bind it with rattan 2 to make a figure 1 Shown bamboo raft, with this bamboo raft as floating body;

[0017] B. chiseling and digging planting hole 3 on the moso bamboo of bamboo raft, planting hole 3 is the through hole that communicates up and down, and the hole distance is 10cm-15cm, and the hole diameter is 5cm-6cm;

[0018] c. wrap the stem nearer to the root of the plant 4 with a sponge, then fix it in the planting hole 3 on the bamboo raft moso, the root of the plant stretches below the bamboo raft, and directly puts it into the hole for the floating plant. The plant 4 is selected to have the ability to enrich arsenic, such as floa...

Abstract

The invention provides a method for processing arsenic polluted water body by enrichment adsorption coupling, which is to place a processing unit in the polluted water body. The processing unit comprises floating bodies, plants and adsorbents; the floating bodies are bamboo rafts made of moso bamboo; the plants select emergent aquatic plants which can enrich arsenic and are fixed on the surfaces of the floating bodies to grow in a floating manner; the adsorbents are contained in an absorbing bag which is hung under the floating bodies; the absorbing bag hung under the bamboo rafts absorbs harmful substance through the adsorbents in a deep layer of the water body; the roots of the floating plants are underwater, which enrich arsenic through the action of plant roots to achieve the purpose of purifying water body. The method of the invention has simple operation, low cost, environmental protection and no pollution; the arsenic removing effect is good by combining the enrichment of plantsand absorption of the absorbents; and the introduction of the plants improves the landscape of the water body and beautifies the environment.

Description

technical field [0001] The invention relates to an arsenic-polluted water body treatment method, which belongs to the technical field of water body purification. Background technique [0002] In recent years, arsenic pollution incidents in rivers and lakes have occurred frequently. For the treatment of these arsenic-contaminated water bodies, the usual method is to transfer water from the outside to dilute the polluted water bodies. However, the dilution method has certain requirements on hydrological and water conservancy conditions and is not easy to control. It is difficult to achieve ideal results in the pollution control of rivers and lakes, and it is still possible to generate excessive "pollution clusters" and push them downstream. In addition, although adding arsenic-removing adsorbents to polluted water bodies can absorb arsenic and settle it to the bottom of the river, complete the treatment of polluted river water and meet the discharge standards, but the settled ...
