Problems solved by technology

However, for a period of time, due to high energy consumption and high operating costs, the construction of urban sewage treatment plants in my country has been hindered. At the same time, some completed sewage treatment plants have been in a state of shutdown and semi-stop production for a long time due to high energy consumption.
For a long period of time in the future, energy consumption will become the bottleneck of urban sewage treatment

Abstract

The invention discloses a high-efficiency multipurpose sewage treatment agent and a sewage treatment method using the same. The high-efficiency multipurpose sewage treatment agent comprises urban sewage treatment plant activated sludge, tobermorite, pinaceae plant waste, concentrated sulfuric acid, sodium hydroxide, polyaluminum phosphate and / or polyaluminum sulfate, and polymeric ferric silicate sulfate. The sewage treatment method has a wide source and a low cost. The urban sewage treatment plant activated sludge, pinaceae plant waste and acidized tobermorite are compounded under the action of microwave to form a main raw material, and the main raw material, sodium hydroxide, polyaluminum phosphate and / or polyaluminum sulfate, and polymeric ferric silicate sulfate are orderly mixed to form the high-efficiency multipurpose sewage treatment agent. The high-efficiency multipurpose sewage treatment agent has the advantages of simple preparation processes and low cost. Quality of discharged sewage treated by the high-efficiency multipurpose sewage treatment agent greatly exceeds the national first order discharge standard. The urban sewage treatment plant activated sludge at the bottom of the comprehensive treatment pool can be used for preparation of organic fertilizer, biomass fuel and / or the high-efficiency multipurpose sewage treatment agent.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an efficient and multi-purpose sewage treatment agent and a method for treating sewage using the same. Background technique [0002] Environmental protection directly affects the sustainable development of our national economy. In the past decades of economic development in our country, due to neglect of environmental protection in development, the current environmental pollution is very serious. Although a large number of control measures have been taken in recent years, the trend of further deterioration of the environment continues. my country is one of the countries with the most serious environmental pollution in the world. Whether it is a city or a village, our country's atmosphere, rivers, lakes, oceans and soil are all polluted to varying degrees. Five cities including Guiyang, Chongqing, Beijing, and Lanzhou are among the top ten cities with the worst air pollution in t...
