Problems solved by technology
But the shortcoming of this method is that a, external drier volume is bigger, and construction cost is high; B, the microcapsule of preparation is usually smaller in size, and it is difficult to disperse when drying; c, core material may remain on the surface of microcapsule; d , microorganisms are sensitive to higher temperature, resulting in lower survival rate

Embodiment 4
[0034] A preparation method of the above-mentioned microbial capsules for wastewater treatment, comprising the following steps:
[0035] Step 1, preparing microbial bacterial agent;
[0036] Fermentation and culture of various microorganisms used for wastewater treatment to the middle and late logarithmic phases, gentle centrifugation, concentration, and washing of the bacteria; then according to the quality of the wastewater, the bacteria of various microorganisms are compounded in corresponding proportions to obtain microbial agents (per gram of microorganisms The microorganisms contained in the bacterial agent (wet weight) are 2~5×10 10 indivual).
[0037] The selected microorganism types and proportioning relationship are known technologies, such as Micrococcus, Bacillus, Alcaligenes, Flavobacterium, yeast, etc. Those skilled in the art can select the proportioning according to the actual needs, and will not repeat them here.
[0038] Step 2. After sterilizing the microp...

The invention discloses a microbial capsule for wastewater treatment. The microbial capsule comprises a capsule shell and a microbial compound inside the capsule shell. The microbial compound comprises, by weight, 80-85% of a microbial agent, 10-12% of microporous starch and 3-10% of active charcoal powder. A preparation method of the microbial capsule comprises the following steps: Step 1, preparing the microbial agent; Step 2, uniformly mixing the microbial agent, microporous starch and active charcoal powder, and culturing to obtain the microbial compound of the microbial agent, microporous starch and active charcoal powder; and Step 3, preparing the microbial capsule. By the microbial capsule for wastewater treatment and the preparation method, the obtained microcapsule has higher bacteria concentration after cultured and can provide more microbes during wastewater treatment so as to greatly enhance wastewater treatment efficiency. By the preparation method, quantity of the microcapsule is minimized, and costs are saved.
Description
technical field [0001] The invention relates to microbial capsules, in particular to a microbial capsule used for wastewater treatment and a preparation method thereof. Background technique [0002] Microbial agents currently used to treat wastewater are generally added directly. Since the microbial inoculum is very sensitive to the environmental conditions of the wastewater, and the microbial inoculum is not resistant to storage, it is necessary to prolong the storage time of the microbial inoculum. [0003] Microbial encapsulation technology refers to the technology of embedding and sealing microorganisms in a specific area with membrane materials through chemical or physical immobilization methods, and maintaining the biological activity of microorganisms. Capsules consist of a core material and a wall material wrapped around the outside. After the formation of microcapsules, the coated substances are isolated from the outside world, and their properties are hardly affe...
