Abstract

The method relates to a sewage water and sludge treatment technology, in particular to a process and equipment for treating municipal sewage water and sludge by utilizing a nepheline nucleated glass technology. The invention solves the problems that the prior incinerator has secondary pollution and upflowing black smoke, etc. in the process of treating the municipal sludge. The process comprises the following steps that: nepheline nucleated glass raw material is used to absorb and filter the sewage water, then sludge water is rapidly separated; upper-layer water is disinfected by steam, volatilizes odor and is further filtered to drinking water; underlayer slurry is mixed with diesel oil and olefin to be used as fuel of a liquation furnace; and residue falls on a hearth and is mixed with the added nepheline nucleated glass raw material to fuse superior nepheline nucleated glass particles, which can be used to produce nepheline nucleated glass and metal mixed powder metallurgical products, mechanical members and building materials. The equipment has a high energy formula of combining a superhigh temperature and bottom inserting-type three-phase electrode liquation furnace and nepheline and realizes the separation of hydrogen and oxygen in the water and the heat release of hydrogen combustion. The process and the equipment have no requirement on the water quality of incoming water, achieve the recovery of purified water and the emission of air without odor and realize the added value utilization of the residua.

Description

technical field [0001] The invention relates to sewage and sludge treatment technology, in particular to a process and equipment for treating urban sewage sludge by using nepheline glass-ceramic technology. Background technique [0002] Urbanization is an inevitable trend of economic development. The most important problem in the service function of the city is the disposal of industrial waste and domestic waste generated every day. Concentrating sludge and garbage in the suburbs for stacking or burying is not only a waste of resources, but also And pollute the surrounding environment. The current sewage treatment technology adopts the microbial digestion method, which requires the repair of a large number of aeration tanks and the administration of drugs, which has strict requirements on the quality of incoming water. Industrial sewage and domestic sewage need to be constructed in separate networks, which not only requires a large investment, but also high operating costs. ...
