Embodiment Construction

[0026] like figure 1 The treatment system for removing heavy metals in industrial wastewater is shown. The system includes a water collection well 1, a coarse grid 2, a micro-bubble air flotation mineral oil adsorption device 3, a catalytic heavy metal desorption reactor 4 for mineral oil, and a rotary pectin-heavy metal Adsorption tank 5, aeration nitrification tank 6, biological denitrification tank 7, sedimentation tank 8, and water purification tank 9; among them, the industrial wastewater containing oil and heavy metals enters the water collection well 1 through the wastewater pipeline, where centralized collection and preliminary stable adjustment are carried out. The outlet of the water collection well 1 is connected to the coarse grid 2 through the wastewater pipeline, where the large-diameter solid matter in the industrial wastewater is removed. The outlet of the coarse grid 2 is connected to the micro-bubble air flotation mineral oil adsorption device 3 through the wa...

Abstract

The invention discloses a system for treating heavy metal industrial wastewater containing oil. The system comprises a water-collecting well, a coarse screen, a microbubble air floatation mineral oil adsorption device, a mineral oil catalysis and heavy chemical desorption reactor, a protopectin-heavy metal rotary adsorption pond, an aeration nitrification pond, a biological nitrogen removal pond, a settling pond and a water purification pond. A V-shaped netty roller containing pumpkin peel is creatively used as a contact reaction medium, when wastewater containing heavy metal is fully mixed with the pumpkin peel, heavy metal ions in wastewater are adsorbed by non-water-soluble protopectin in pericarpic cells, and part of residues precipitate at the bottom of the adsorption pond to form sludge matter gradually. Meanwhile, the pumpkin peel in the V-shaped netty roller can be replaced according to consumption conditions as a low-cost consumable.

Description

technical field [0001] The invention relates to a treatment system for oil-containing heavy metal industrial wastewater, which belongs to the field of wastewater treatment in environmental protection. Background technique [0002] Heavy metal pollution refers to environmental pollution and ecological damage caused by heavy metals and their compounds, and the degree of harm depends on the concentration and chemical form of heavy metals in the environment, food and organisms. Heavy metal pollution is mainly manifested in water pollution, and partly in the atmosphere and solid waste. Heavy metal pollution is different from the pollution of other organic compounds. Many organic compounds can be purified through the physical, chemical or biological effects of nature itself, so that the hazards can be reduced or eliminated; while heavy metals are enriched and difficult to degrade in the environment. [0003] From the perspective of environmental pollution, the most representative...
