An assemble type multifunctional habitat platform for animals comprises a support and a habitat plate, the support is installed on the wall, two or more supporting seats which are adjustable in height and perpendicular to the wall face are installed on the support, the habitat plate which is arranged horizontally is connected with the supporting seats in a sliding mode, the habitat plate comprises a habitat plate body of which the side, far away from the wall face, can turn upwards and fold and a width extension plate on the side near the wall face, the upper surface of the width extension plate is flush with the upper surface of the habitat plate body, gaps are formed between the lower side of the width extension plate and the supporting seats, width extension supporting blocks of which the size is matched with that of the width extension plate are fixed in the gaps, the two sides of the habitat plate body are connected with length extension plates respectively, and when the length extension plate slide outwards, the length extension plates form the habitat plate lengthening areas. According to the assemble type multifunctional habitat platform for the animals, the height, the length and the width can be adjusted according to animal species, ages, body sizes and climbing and jumping abilities, rest comfort of the animals is improved, the physique is enhanced, diseases and death are reduced, and breeding is promoted.

A method of preparing a special sulfate cementing material through treatment on electrolytic manganese residues in a fluidized bed boiler includes the following steps: 1) material preparation: metering and preparing following raw materials comprising, by weight, 45-80 parts of the electrolytic manganese residues, 8-25 parts of stone coal and 10-45 parts of waste stone residue; (2) preparation of matured slag: continuously feeding the weighed and prepared raw materials into the fluidized bed boiler, roasting the raw materials under an oxidizing atmosphere at 800-1280 DEG C for 0.3-1.5 h with overflow rapid-cooling at a material outlet to obtain the matured slag; and (3) preparation of the special sulfate cementing material: grinding the matured slag until sieve residue mass of the matured slag is not more than 20% through a 80 [mu]m sieve to obtain the special sulfate cementing material. According to the method, the special sulfate cementing material contains various hydrated active minerals, so that the material can be widely used in cement industry, is high in strength during use, and has an excellent strength when being used as activated slag powder or for producing building materials. The method is less in investment, is free of waste water and waste residue and is good in economy.
