Embodiment Construction
[0013] The invention provides a controllable porous microbial carrier. Made by following steps:
[0014] 1) Porous carrier material: use materials with low density and easy large-scale processing;
[0015] 2) Porous spherical layers with different diameters are produced separately first, and then assembled together to form a porous carrier, and various environments of anaerobic, microaerobic and aerobic are formed inside and outside the carrier.
[0016] The above-mentioned porous nested layer may be spherical, cubic, cuboid or polygonal. The materials of its composition are: synthetic or natural materials of plastic, PVC, UPVC or using recycled waste plastic. The pores on the spherical porous layer are rhomboid, circular or rectangular.
[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Abstract
The present invention belongs to the field of sewage treating technology, and relates to one kind of porous microbial carrier with outstand effects of reducing sludge amount and immobilizing microbe. It is formed via embedding porous layers of different shapes, spherical, cubic, cuboid or polyhedral. The pores may be in different shapes, and the material for the carrier may be plastic or other easy-to-machine anticorrosive material, including reused material. It is used to fix microbe and promote reduction of sludge, and may be used in producing aerobic, slightly aerobic and anaerobic environments. It may separate water from sludge while treating sewage, and has long service life, low production cost, great specific surface area and other advantages.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a porous microbial carrier which has outstanding effects on the reduction of excess sludge and the immobilization of microorganisms. Background technique [0002] The use of carriers in the activated sludge method and biofilm method can immobilize microorganisms and increase the concentration of microorganisms in the reactor, thereby improving the treatment efficiency of the reactor. Commonly used carriers include fillers such as sand, gravel, anthracite, coke, porcelain rings, soft fibers, etc., but these carriers can only form biofilms on the surface of the carrier, with relatively small biomass and a relatively single microbial environment. [0003] Porous carrier is a new type of carrier that has attracted much attention in recent years. It is mainly used to immobilize microorganisms and increase the total amount of microorganisms in the system. Moreover...
