ANAEROBIC APPARATUS FOR WASTE WATER TREATMENT

摘要

The organic waste water is treated by a biological anaerobic process. A waste water sipplier(12) is installed in a lower part of a reaction tank, a gas-sludge separation apparatus in an upper part. A gas flow apparatus(14) is installed in a lower part of the gas-sludge separation apparatus to prevent a loss of a generated gas, and a waste water runoff path(15) is installed in the reaction tank(5). A sub-separation apparatus(16) of the gas-sludge is also installed in a lower part of the separator(13), it has a shape of vertical diaphragm, a size of about 1.2 times of the main separator. The sludge is separated forming an upstream in an inner part and a downstream in an outer part of the sub-separator(16).
