Problems solved by technology

However, this magnetic separation temporary pollution control measure can only remove part of the insoluble pollutants, and the removal rate of ammonia nitrogen and total phosphorus is extremely low. The water quality after magnetic separation treatment is still of inferior water quality. It is easy to produce a large amount of chemical sludge, which will cause secondary pollution to the environment

Abstract

The invention provides an aggregate composite purification carrier which comprises an aggregate carrier, an adhesive layer and a composite bacteria layer, the adhesive layer covers the surface of the aggregate carrier, the composite bacteria layer is arranged on the adhesive layer, composite bacteria in the composite bacteria layer comprise COD degrading bacteria and ammonia nitrogen degrading bacteria, the adhesive layer comprises polyvinyl alcohol, sodium alginate and gelatin, and the adhesive layer is arranged on the surface of the aggregate carrier. The concentration ratio of the polyvinyl alcohol to the sodium alginate to the gelatin is 40: 6: 1, the thickness of the adhesive layer is 0.01-3mm, and the weight ratio of the adhesive layer to the compound bacteria layer is 10: 1. Sodium alginate and gelatin in the adhesive layer can provide nutrients for COD degrading bacteria and ammonia nitrogen degrading bacteria in the compound bacteria liquid, so that the COD degrading bacteria and the ammonia nitrogen degrading bacteria can have longer life cycles, the black and odorous water body is more favorably purified, the aggregate carrier, the adhesive layer and the compound bacteria layer do not pollute the environment, and the service life of the black and odorous water body is prolonged. Therefore, the aggregate composite purification carrier can purify polluted water in an environment-friendly manner.

Description

technical field [0001] The invention relates to the field of biological water purification, more specifically, to an aggregate composite purification carrier. Background technique [0002] At present, the relatively advanced treatment measures for black and odorous water bodies are temporary pollution control measures of magnetic separation. The temporary pollution control measures of magnetic separation use the magnetism of impurity particles in wastewater to separate them. For non-magnetic or weakly magnetic particles in water, magnetic inoculation technology can be used. make them magnetic. With the help of the external magnetic field, the magnetic suspended solids in the wastewater are separated, so as to achieve the purpose of purifying the water. However, this magnetic separation temporary pollution control measure can only remove part of the insoluble pollutants, and the removal rate of ammonia nitrogen and total phosphorus is extremely low. The water quality after m...
