Description

A kind of composite highly effective sewage-treating agent based on natural crystal and preparation method thereof
Technical field
The present invention relates to sewage treatment area, specifically a kind of composite highly effective sewage-treating agent based on natural crystal and its Preparation method.
Background technology
Environmental protection directly affects the sustainable development of Chinese national economy.In the economic development of China's the past few decades In, due to ignoring developing environmental protection, it 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 further deteriorates still is continuing.China is the state the most serious of environmental pollution in the world One of family, either city, or rural area, air, river, lake, ocean and the soil in China etc. is by different degrees of Pollution.
In national annual sewage discharge, only 10% sanitary sewage and 70% trade effluent are handled, and wherein there are about The water outlet of half Industrial Waste Water Treatments facility does not reach discharging standards, and remaining untreated sewage is then directly discharged into rivers lake In pool, the water environment in China is caused to be subject to serious pollution and destroy;The discharge capacity of town domestic sewage is just with city-building With development and be in incremental trend, urban ground water pollution is generally serious, and in the trend that further deteriorates, about 50% city Underground water is caused to seriously endanger by different degrees of pollution to people's health.
China's urban sewage treatment process is generally using traditional activated sludge process, oxidation ditch, SBR etc. at present, these Ripe and effective handling process, is widely used in various regions.But for a long period, hindered 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 place In stopping production and half end-of-life state.Within one considerably long from now on period, energy consumption problem is by as the bottleneck of municipal sewage treatment. Can solve the energy consumption problem of sewage plant, rationally carry out energy distribution, oneself, which turns into, determines sewage treatment plant's on-road efficiency quality Key factor, and the deciding factor of following new sewage treatment plant's feasibility analysis, develop be adapted to China's national situation it is efficient, Low consumption and emission request can be met, and capital construction and the low New Technology about Wastewater Treatment of operating cost and new technology, will be future Designing Sewage Treatment Plant and the only way of operation, are of great practical significance.
