Problems solved by technology

[0003] However, the following problems exist in the traditional biological denitrification technology: ① Due to the uneven concentration of dissolved oxygen at different depths of the water body, nitrification (the nitrification process is an oxygen-consuming process) bacteria themselves cannot be enriched in large quantities on the surface of the water body, thus affecting its biological ② Due to the shortage of some nutrients and carbon sources, effective microorganisms cannot survive in the water body or the survival time is too short; ③ Due to their own gravity, a large number of microorganisms settle into the bottom mud of the water body and lose their dissolved state in the degraded water body The role of nitrogen; ④ Some polymer immobilized microbial carriers cannot degrade themselves, resulting in secondary pollution of water bodies
[0004] Due to the traditional biological denitrification process, there are many disadvantages such as autotrophic nitrifying bacteria can not get the growth advantage, it is difficult to maintain a high biological concentration, the investment and operation costs are high, and it is easy to cause secondary pollution.

Embodiment 1

[0059] The processing steps of the present embodiment are as follows:

[0060] 1. Processing of bagasse molasses

[0061] Due to the complex composition of sugarcane molasses, mixed with a large number of non-sugar components and impurities (such as melanin, heavy metal ions, colloidal substances, etc.), the BOD and chroma of the treated water will increase. Therefore, these impurities must be removed before making immobilized microbial carriers. Firstly, the bagasse is crushed, heated to squeeze the juice, cooled, and the impurities are precipitated. Filter the supernatant, then heat to squeeze the juice, precipitate, and filter, and repeat it many times to obtain dark brown high-viscosity liquid molasses. The obtained molasses contains not only sugar, but also mineral elements such as calcium and potassium and various amino acids, which are suitable as carbon sources and nutrients for heterotrophic microorganisms such as denitrifying bacteria.

Embodiment 2

[0077] In order to realize the new energy source instead of coal and oil---the microbial production of H2 and the influence of ammonia-containing wastewater on hydrogen-producing bacteria, that is, new energy can be produced while treating wastewater. By preparing immobilized hydrogen-producing bacteria carriers, the tolerance of hydrogen-producing bacteria to wastewater containing ammonia is improved, and the hydrogen production capacity of hydrogen is also increased. 3 times the hydrogen production of bacterial support culture.

[0078] The processing steps of the present embodiment are as follows:

[0079] 1. Processing of bagasse molasses

[0080] Due to the complex composition of sugarcane molasses, mixed with a large number of non-sugar components and impurities (such as melanin, heavy metal ions, colloidal substances, etc.), the BOD and chroma of the treated water will increase. Therefore, these impurities must be removed before making immobilized microbial carriers. ...

[0093] The preparation of the immobilized lactic acid bacteria carrier is as a feed microbial additive, which is administered orally to cultured animals to improve the immunity of aquatic animals, and is also used as a water body micro-ecological regulator to improve water quality.

[0094] The processing steps of the present embodiment are as follows:

[0095] 1. Processing of bagasse molasses

[0096] Due to the complex composition of sugarcane molasses, mixed with a large number of non-sugar components and impurities (such as melanin, heavy metal ions, colloidal substances, etc.), the BOD and chroma of the treated water will increase. Therefore, these impurities must be removed before making immobilized microbial carriers. Firstly, the bagasse is crushed, heated to squeeze the juice, cooled, and the impurities are precipitated.

Abstract

The invention provides an embedding device and a preparation method of an immobilized microbial carrier. The embedding device includes an inner pipe, a first intermediate pipe, a second intermediate pipe and an outer pipe. According to the embedding device and the preparation method of the immobilized microbial carrier, the novel immobilized microbial carrier is prepared by double embedding, the aeration resistant intensity of the immobilized microbial carrier is enhanced, the mechanical strength is high, no polyvinyl alcohol and sodium alginate dissolves out, and the influence of the treatedenvironment on the immobilized microbial carrier is resisted; meanwhile, the water swellability of the immobilized microbial carrier is retarded, the mechanical strength and the biological activity ofthe carrier are improved, and the service life of the carrier is prolonged; and thus industrial scale production of the immobilized microbial carrier can be realized through the embedding device, andthen the cost of wastewater treatment is lowered.

Description

technical field [0001] The invention relates to sewage treatment, in particular to an embedding device with fast solidification speed and high hardness after solidification and a manufacturing method of immobilized microorganism carrier. Background technique [0002] The most fundamental technology of denitrification is inseparable from the degradation of microorganisms. The screened high-efficiency nitrifying bacteria and denitrifying bacteria are the core bacteria in the sewage biological denitrification technology. Biological denitrification technology first converts ammonia nitrogen into nitrate nitrogen through the nitrification of nitrifying bacteria, and then converts the latter into nitrogen gas and discharges it into the atmosphere through denitrification, finally realizing the cycle of nitrogen elements and the harmlessness of ammonia nitrogen . [0003] However, the following problems exist in the traditional biological denitrification technology: ① Due to the u...
