Artificial root filler unit, biological carrier and biofilm bioreactor module

Abstract

The invention provides an artificial root system packing unit which comprises a microorganism accelerant supply tube, wherein at least two prism silk screen components or inverted arc-shaped silk screen components are distributed in the length direction of the microorganism accelerant supply tube; at least two micro-pores through which a microorganism accelerant can flow to the prism silk screen components or the inverted arc-shaped silk screen components are arranged at the connecting parts of the microorganism accelerant supply tube and the prism silk screen components or the inverted arc-shaped silk screen components. The invention further provides a biological carrier consisting of a plurality of the artificial root system packing units which are arranged together, and a biological membrane bioreactor module formed by a plurality of the biological carriers which are arranged together. Microorganism accelerant supply tubes can be communicated through a gathering tube. A biological membrane method and a catalytic microorganism growth technique can be combined, the artificial root system packing unit is large in specific surface area, has the characteristics that the membrane can be easily hung, microorganism growth can be easily promoted, and the microorganism biological activity can be improved, excellent biologic and physical and chemical property can be achieved, and the microorganism activity can be effectively improved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an artificial root filler used in the urban sewage treatment process, and also relates to a biological carrier using the artificial root filler and a biofilm bioreactor with the biological filler. Background technique [0002] With the development of modern industry and urban construction, the problem of water pollution in my country's cities has become increasingly serious, and sewage treatment technology has become an essential part of maintaining sustainable social and economic development. Various new sewage treatment processes based on physical, chemical and biological principles continue to emerge, among which biological treatment technology has always occupied an important position, and biofilm method is an important process in sewage biological treatment technology. As early as the 19th century, Germany began to use the biofilm method for wastewater treatment, but it was n...

Problems solved by technology

Since then, domestic manufacturers have successively introduced a variety of combined packing, but they have only made some improvements in the structure of the central ring and the number and length of fiber bundles, and the structural design has not jumped out of the scope of shield packing. Performance is also similar to shield packing
