Embodiment Construction

[0023] Such as figure 1The shown treatment system for removing heavy metals in industrial wastewater includes a water collection well 1, a coarse grid 2, a primary sedimentation tank 3, a pH value adjustment tank 4, a protopectin-heavy metal rotary adsorption tank 5, and an aeration nitrification tank 6 , biological denitrification tank 7, secondary sedimentation tank 8, water purification tank 9, etc.; among them, the industrial wastewater containing heavy metals enters the water collection well 1 through the waste water pipeline, where it is collected and initially stabilized, and the outlet of the water collection well 1 passes through The wastewater pipeline is connected to the coarse grid 2, where the large-diameter solid matter in the industrial wastewater is removed. The outlet of the coarse grid 2 is connected to the primary sedimentation tank 3 through the wastewater pipeline, where the insoluble substances in the wastewater are further removed. The outlet of the prima...

Abstract

The invention discloses a treatment system for removing heavy metals in industrial wastewater. The treatment system comprises a water collecting well, a coarse screen, a primary settling pond, a pH value adjusting pond, a protopectin-heavy metal rotary adsorption pond, an aeration nitration pond, a biological nitrogen removal pond, a secondary settling pond and a clear water pond. A V-shaped net-shaped roller filled with pumpkin peel is creatively used as a contact reaction medium, when the wastewater containing the heavy metals is fully mixed with the pumpkin peel, heavy metal ions in the wastewater are adsorbed through the adsorption effect of non-water-soluble protopectin in peel cells, some residues settle at the bottom of the adsorption pond, and sludge matter is gradually formed. Meanwhile, the pumpkin peel in the V-shaped net-shaped roller serves as a low-value consumable and can be replaced according to the use and consumption condition.

Description

technical field [0001] The invention relates to a treatment system for removing heavy metals in 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 h...
