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 sewage processing agent with addition of a synergist, which comprises the following raw materials of sewage plant activated sludge, a composite adsorbent, coke slag powder, concentrated sulfuric acid with mass concentration being more than 90%, calcium oxide and the composite synergist. The raw materials have the advantages of wide source and low cost; the main raw material can be obtained by compositing the sewage plant activated sludge and the coke slag powder and the acidified composite adsorbent under microwave effect, and the main raw material is mixed with calcium oxide and the composite synergist in order to obtain the sewage processing agent. The method has the advantages of simple process and low cost. According to the sewage processing agent for processing sewage, the discharge quality of the processed sewage can exceed a national first level standard; and the sewage plant activated sludge at bottom of a comprehensive treatment pool can be used for preparing organic fertilizer or biomass fuels.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment agent added with a synergist. 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 the world. Among the more than 600 cities in the countr...
