Description
Technical field
The present invention relates to technical field of sewage, more particularly, to a kind of method for sludge treatment.
Background technology
Mud is the solid waste producing in sewage disposal process, with the development of domestic sewage disposal cause, sewage
Factory's total process water yield and degree for the treatment of will constantly expand and improve, and the sludge quantity of generation also increasingly increases, the process investment of mud
Very huge with operating cost, the expense for Treatment of Sludge accounts for the 20%～50% of sewage treatment plant's operating cost, to sewage
Treatment plant brings white elephant.Except containing the nutrient substance such as substantial amounts of Organic substance and nitrogen, phosphorus, also existing in sewage sludge
The poisonous and harmful elements such as heavy metal, pathogenic bacterium and parasite.For preventing secondary pollution that mud causes and ensureing sewage treatment plant
Normal operation and treatment effect, the processing of sewage sludge dispose the position occupied in wastewater treatment in China and become increasingly conspicuous.
Municipal sewage plant mud concentrated and dehydration after, mud can carry out health in moisture content 80% about, dewatered sludge
Landfill, fermentation system are fertile, drying and other treatment.The direct landfill disposal of mud can affect the normal operation of landfill yard, and takies landfill yard
A large amount of areas, are prohibited to adopt at present.Because China's Heavy Metal Level In Sludge is exceeded, if agricultural after sludge composting can affect
The value of crops, market acceptance level is low.Sludge drying technique typically adopts steam as thermal source, is " with hot heat exchange ", energy
Consumption is higher, and operating cost is high；And also there is dust explosion risk in high temperature drying.Using mud pyrohydrolysiss breaking cellular wall, need to use
High temperature heat source heats mud, and energy consumption is higher；And also there is potential safety hazard in actual production high temperature thermal source.
In prior art, moisture percentage in sewage sludge height is restriction sludge treatment and utilizes key issue, comprises in biological sludge
The moisture of different conditions, including Free water, Interstitial Water, absorption water and surface-bonded water.Conventional dehydration technique can only remove freedom
Water and portion gap water, the clearance of mud intercellular substance water is very low.Accordingly, it would be desirable to the new means of research and development improve dirt with effective
Mud goes water rate, and meanwhile, as sludge treatment technique in addition it is also necessary to resource consumption is few, and environmental pollution is little.
Content of the invention
It is an object of the invention to provide a kind of method for sludge treatment, the dewatering of mud can be effectively improved, beneficial to dirt
Mud processes reduces cost.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of method for sludge treatment, comprises the following steps:
(1) silicon dioxide, boron oxide, yittrium oxide, magnesium oxide, boron oxide are mixed to prepare mixed-powder；Again by mixed-powder in 1500
DEG C melting 1 hour, chilling obtains block；Cross 325 mesh standard sieves after block is pulverized, obtain ceramics；Then by ceramics with addition of
Pressure ball after Calx mixing；Sinter 1 hour after 1200 DEG C after 950 DEG C of sintering half an hour, obtain ceramic body；
(2) butyl acrylate, n- n-methylolacrylamide, styrene and isomerous tridecanol polyoxyethylene ether are added water
In make emulsion；Then Deca persulfate aqueous solution, reacts 1.5～2 hours in 70～75 DEG C, obtains the slurry of inert polymer
Material；
