Anaerobic microbial filler

Abstract

The invention relates to the technical field of wastewater treatment, and discloses an anaerobic microbial filler, which comprises a supporting frame, a second filler block, and a plurality of first filler blocks, each first filler block is articulated with the supporting frame, each first filler block is obliquely fixed on the second filler block, both the second filler block and the plurality offirst filler blocks need to be soaked in solution for 2 to 3 months, and the solution is prepared from the following components in part by weight: 8 to 12 parts of nitric acid, 0.5 to 1.5 parts of phosphoric acid, 0.8 to 1.2 parts of ferric oxide, 0.8 to 1.2 parts of calcium sulphate, 0.8 to 1.2 parts of magnesium oxide, 0.8 to 1.2 parts of potassium oxide and 135 to 145 parts of water. In orderto solve the problem existing in the prior art that environmental accidents can take place due to substandard effluent quality because microbial filler cannot continuously provide trace elements. According to the solution, by soaking both the second filler block and the plurality of first filler blocks in the solution, trace elements can be continuously replenished to the filler bodies, consequently, effluent quality can up to standard, and the occurrence of environmental accidents can be prevented.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an anaerobic microbial filler. Background technique [0002] In the prior art, the materials of microbial fillers are polyethylene, vinylonized venilon silk, etc. Generally, when in use, it is necessary to add a nutrient solution containing trace elements such as nitrogen, phosphorus, and iron into the microbial fillers; in sewage treatment, the main function of fillers is It is the growth of microorganisms attached to the microbial filler; on this kind of microbial filler, the growth of microorganisms is generally better in the early stage, which can meet the needs of sewage treatment, but as time increases, the growth of microorganisms requires continuous trace elements, and this kind of microbial filler cannot Continuously provide any trace elements, so after a long time of use, microorganisms will have varying degrees of disease, resulting in pollutants that cannot b...
