Abstract

The invention relates to a manufacturing method of a flow-separated ball carrier for sewage treatment. The manufacturing method of the flow-separated ball carrier for sewage treatment comprises the following steps of (1) according to the weight percentage, mixing 77 to 86 percent of red soil, 7 to 12 percent of ground hydrated lime, 4 to 7 percent of hemihydrate gypsum powder, and 3 to 5 percent of cement, and uniformly stirring to obtain a mixture; (2) adding water with the weight being 0.3 to 0.4 times of the weight of the mixture into the mixture, and preparing to obtain a pug; (3) placingthe pug in a hollow part in a flow-separated ball mould with a steel needle, pulling out the steel needle through extrusion or compression moulding, and obtaining a flow-separated ball carrier finished product with recesses, honeycomb holes and a channel space; and (4) naturally drying the flow-separated ball carrier finished product for 14 to 21 days at room temperature, and obtaining the flow-separated ball carrier with a structure with different honeycomb hole and micro-hole sizes. The manufacturing method of the flow-separated ball carrier for sewage treatment provided by the invention issimple in production process and low in cost; and a prepared flow-separated ball filler is short in membrane-forming time, easy to form a membrane, and capable of realizing automatic membrane-formingsince no any activated sludge is added for bacterium cultivation in the experimental process.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a manufacturing method of a floating ball carrier used for sewage treatment. Background technique [0002] Floating ball is a common decontamination method for sewage treatment by using the floating biological method. It mainly uses the phenomenon of drifting to separate the organic matter and impurities in the sewage from the water, that is, the polluted water flows through the surface of the drifting ball and the phenomenon of drifting occurs in the water. The organic matter and microorganisms attached to the surface of the carrier, the organic matter in it is conducive to the growth and reproduction of microorganisms, and gradually forms a layer of biofilm on the surface of the carrier. This layer of biofilm has biochemical activity, which can further adsorb and decompose sewage pollutants. [0003] At present, the flow glass ball carrier is divided according to the ...
