Problems solved by technology

Studies have shown that the enrichment of F-53B can cause embryonic developmental toxicity and cardiac developmental toxicity in fish, and affect the malignant changes in fish body weight and thyroid hormone levels
[0004] In the treated electroplating industrial treatment water, there are still some trace and trace organic pollutants and heavy metals such as F-53B entering the water body to pollute the water source. The concentration of these pollutants is very small, con

Embodiment 1

[0023] Such as figure 1 , an advanced treatment method for removing trace heavy metals and traces of F-53B in the effluent of electroplating wastewater treatment. After the terminal sedimentation tank of electroplating wastewater treatment, there are microbial degradation area, algae adsorption area, emergent plant area, floating water plant area and sedimentation tank in sequence. water plant area.

[0024] Put the composite microbial agent in the microbial degradation zone, promote the reproduction and growth of the composite microorganism through the micro-bubble aeration system, and set up carbon fiber filler to provide attachment for the microorganism; the composite microbial agent includes Rhodopseudomonas, Bacillus subtilis, Alcaligenes, actinomycetes, nitrifying bacteria, nitrogen-fixing bacteria, lactic acid bacteria, rhodocyclobacteria, Sclerotia, the content ratio of the compound microbial agent is 2:2:2:1:1:1:0.5 :0.5:0.5, the feeding ratio is 0.2kg / m 3 . Accord...

Embodiment 2

[0032] A certain electroplating wastewater is discharged into natural rivers after treatment, such as figure 2 , each treatment area is set along the natural river, the content ratio of the compound microbial agent is 2:2:2:1:1:1:0.5:0.5:0.5, and the distribution ratio is 0.1kg / m 3 . According to the water surface area every 5m 2 Set and install a carbon fiber tube bundle filler, corresponding to a microbubble aerator with a diameter of 20cm at the bottom of the river. One or more of chlorella, oscillating algae or anabaena are cultivated in the algae adsorption area, and a surface aerator can be installed to make the water in the algae adsorption area evenly mixed. The setting of intercepting net is the same as embodiment one.

[0033] Emergent plant areas, floating plant areas, and submerged plant areas are set along the natural channel. The plants planted in the emergent plant area are cattail and Zailihua, the plants planted in the floating plant area are water lilies...

Abstract

The invention provides a treating method for removing trace heavy metal and trace F-53B in electroplating wastewater treatment effluent. By setting a microorganism degradation zone, nitrogen and phosphorus and a part of organic matters in industrially treated wastewater can be removed by utilizing compound microorganisms; by setting an algae adsorption zone, trace organic matters in wastewater canbe adsorbed by utilizing algae cells, and refractory trace organic matters in the wastewater can be fixed; by setting an intercepting net and filling volcanic, carbon residue and magnetite residue, heavy metal in the wastewater can be synergistically reduced; by setting an emergent plant zone, a floating plant zone and a submerged plant zone, ecologic degradation can be further carried out on a water body. A device can also be arranged in a natural river channel, so that the natural river channel can be repaired, the visibility of the water body can be improved, and enrichment of the heavy metal and the refractory organic matters in aquatic animals and plants can be reduced.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to an in-depth method for removing trace amounts of heavy metals and trace amounts of F-53B in electroplating wastewater treatment effluent. Background technique [0002] Electroplating is one of the basic processes of the manufacturing industry, which has greatly promoted the development of my country's economy and society. However, along with benefiting mankind, a large amount of electroplating wastewater, such as plating parts cleaning wastewater, waste bath liquid, equipment cooling liquid, and waste plating liquid, is also produced during the electroplating production process, making electroplating one of the three major polluting industries in the world today. In the prior art, electroplating wastewater is treated and discharged into natural rivers through multi-stage physical, chemical and biochemical treatment methods. However, even if the treated sewage is discharged, becau...
