Embodiment 1

[0042] like figure 1 Shown, the preparation method of a kind of novel ceramsite of the embodiment of the present invention, comprises the steps:

[0043] Step 1: Dry

[0044] The various raw materials for preparing the new ceramsite are transported to the dryer through a conveyor for drying, and dried until the moisture content is not higher than 3%, and then the raw materials are stored in the raw material warehouse for use;

[0045] Step 2: Shred

[0046] The bulk materials in the raw materials for preparing the new ceramsite are transported to the crusher through a conveyor for crushing, and the particle size after crushing is 1 mm; then other small particle materials in the raw materials for preparing the new ceramsite are And the materials crushed by the crusher are respectively put into the resonance mill or ball mill for grinding or ball milling; finally, they enter the winnowing and classifying machine for winnowing. Transported to the storage bin for storage;

Abstract

The invention discloses a preparation method of novel ceramsite and application of the novel ceramsite in a black and odorous water body. The preparation method of the novel ceramsite comprises the steps of drying, crushing, sieving, mixing, modifying, granulating, calcining and forming and the like. The application of the novel ceramsite in the black and odorous water body comprises the step of putting 50-200 g of the prepared novel ceramsite into each cubic meter of the black and odorous water body to purify the water quality. According to the invention, most of the raw materials are renewable resources and solid wastes, the raw materials are used for preparing the ceramsite, solid waste recycling and renewable resource utilization are achieved, the novel ceramsite is used for black and odorous water body treatment so as to effectively improve the water quality, reduce the organic matter content and improve the water body oxygen dissolution content, the ceramsite prepared from the sludge is low in heavy metal leaching rate, and the preparation method is simple and low in cost.

Description

technical field [0001] The invention relates to the technical field of ceramsite preparation, in particular to a preparation method of a novel ceramsite and its application in black and odorous water bodies. Background technique [0002] At present, a large amount of sewage and various garbage in the city has not been completely treated, and is discharged into the river through various channels, which has far exceeded the pollution-holding capacity of the river, resulting in a large increase in organic matter in the water, a sharp decrease in dissolved oxygen, and the microbial Under the action, NH3-N, humus, H2S, CH4 and other odorous substances and blackening substances such as FeS and MnS are produced, thereby causing black and odorous phenomena. Black and odorous water not only affects the working and living environment of surrounding residents, but also causes great harm to human health. Therefore, the research and treatment of black and odorous water body has increasi...
