Embodiment 1

[0049] A biological basket for removing pollutants in waste water provided by the present invention comprises a basket body with an open upper end, the basket body is equipped with a modified suspension filler, and a composite microbial bacterial agent is solidified on the modified suspension filler; The open end of the basket body is provided with an intercepting device 2 on the outside of the suspended filler.

[0050] As an optional embodiment, the modified suspension filler is an aerobic nitrification filler, an anaerobic / anoxic filler or a redox medium filler. Generally speaking, aerobic nitrification packing is suitable for the treatment of pollutants in natural water bodies and aerobic biochemical pools; anaerobic / anoxic packing is suitable for the treatment of pollutants in anoxic / anaerobic biochemical pools; redox media packing is suitable for Treatment of pollutants in chemical inorganic wastewater. Generally, the dosage of filler is calculated according to the para...

Abstract

The invention provides a biological basket for removing pollutants in wastewater and a preparation method. The invention aims to overcome the technical problems that sewage treatment equipment is large in occupied area, inconvenient to install and large in the number of corollary equipment in the prior art. The biological basket comprises a basket body with an opening in the upper end, wherein a modified suspended filler is arranged in the basket body, and a composite microbial agent is immobilized on the modified suspended filler; and an intercepting device is arranged at the open end of thebasket body and on the outer side of the suspended filler. According to the biological basket for removing the pollutants in the wastewater, the composite microbial agent is immobilized on the modified suspended filler by adopting an adsorption method to prepare the modified suspended filler immobilized with the composite microbial agent, and then the modified suspended filler is placed in the basket body, so the biological basket has the advantages of small occupied area, convenience in installation and few corollary equipment.

Description

technical field [0001] The invention relates to a waste water treatment device, in particular to a biological basket for removing pollutants in waste water and a preparation method thereof. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] According to its principle of action, sewage treatment can be divided into three types: physical method, biological method and chemical method. [0004] ①Physical method: It mainly uses physical action to separate insoluble substances in sewage, and does not change the chemical properties during the treatment process. Commonly used ar...
