Description
Technical field
The present invention relates to sewage treatment area, specifically a kind of composite highly effective sewage-treating agent based on silica flour.
Background technology
Environmental conservation directly affects the sustainable development of Chinese national economy.Economic development in China's the past few decades
In, due to ignoring developing environmental conservation, result in the extremely serious situation of environmental pollution at this stage.Though took in recent years big
The control measure of amount, but the trend that environment is further deteriorated is still in continuation.In national annual sewage discharge, only 10% life is dirty
Water and 70% trade effluent are processed, and wherein be there are about the water outlet of half Industrial Waste Water Treatments facility and do not reached national discharge
Standard, remaining untreated sewage are then directly discharged in rivers and lakes, cause the water environment of China to be subject to severe contamination and break
Bad；The discharge capacity of cities and towns and city domestic sewage is just in incremental trend with city-building and development, and in further
The trend of deterioration, about 50% urban groundwater are polluted by different degrees of, cause serious harm to people's health.
China's urban sewage treatment process generally uses traditional activated sludge process, oxidation ditch, SBR etc. at present, these
Ripe and effective handling process, is widely used in various places.But for a long period, hinder because energy consumption is big, operating cost is high
Hinder the construction of municipal sewage plant of China, at the same some sewage treatment plants for building up also because of high energy consumption the reason for, long-term locate
In stopping production and half end-of-life state.Within one considerably long from now on period, energy consumption problem will become the bottleneck of municipal sewage treatment.
Therefore, on sewage disposal is solved the problems, such as, reduce processing cost and optimization process, be current all Sewage Plant institutes face
The common issue that faces；And one of emphasis is also always for the selection of sewage-treating agent.
Although existing sewage-treating agent has met existing needs, the raw material of these sewage-treating agents need into
Row is produced for second, and its cost is high, and the energy consumption for producing is also larger, always cannot to the cost of many sewage treatment plants
Effectively reduce.
