Problems solved by technology

At present, most calcium peroxide sold in the market is powdery. If the calcium peroxide in minutes is put into the water body, the powder will easily float with the wind. The bottom of the pond, and the specific surface area of ​​the powder in contact with the water is large, the stocking is rapid, and it is easy to release oxygen on the surface of the water body or before sinking to the bottom. Oxygen is released too quickly and cannot be absorbed by the water body immediately, resulting in waste of oxygen. The effect of calcium peroxide cannot be fully exerted

Abstract

The invention discloses a novel inorganic-organic material synergistic speed-differential biochemical ball. The ball consists of a hollow spherical shell and a composite filler in the hollow sphericalshell. A preparation method comprises the following steps: heating and melting polyurethane, adding volcanic rock particles and calcium peroxide powder, fully mixing, pouring the mixture into a mold,cooling until the center temperature is not higher than 110 DEG C, putting filamentous polylactic acid fibers into the mold to wrap the filamentous polylactic acid fibers by taking a mixture of the volcanic rock particles, the calcium peroxide powder and the polyurethane as an outer layer, fully shaping, carrying out demolding treatment to obtain a composite filler, with the filamentous polylactic acid fibers being positioned in the center of the composite filler; and putting the composite filler into the hollow spherical shell to obtain the inorganic-organic material synergistic speed-differential biochemical ball. The speed-differential biochemical ball disclosed by the invention has the advantages of large impact load resistance, no need of an activated sludge cultivation stage, capability of automatically forming a film, small amount of generated sludge, simplified treatment process, capability of reducing secondary pollution of the sludge to the minimum extent and good treatmenteffect.

Description

technical field [0001] The invention relates to the technical field of biological water treatment equipment, and more specifically relates to a novel inorganic-organic material synergistic rapid separation biochemical ball and a preparation method thereof. Background technique [0002] For areas where fresh water resources are scarce and urban water supply is seriously insufficient, domestic sewage, waste water and some industrial waste water are used as reclaimed water sources. After purification, the water quality standards for domestic miscellaneous water can be met, which can alleviate the shortage of water resources and play a role The purpose of preventing water pollution and protecting the environment. As a new biological treatment technology, the speed separation ball technology originated in Japan has been applied in domestic reclaimed water treatment, and the effect is very good. In practical applications, polyurethane, volcanic rock, clay, plant fiber, etc. are o...
