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 multipurpose sewage treating agent and a method for treating sewage by using the same. The efficient multipurpose sewage treating agent comprises the following raw materials: activated sludge of an urban sewage treatment plant, montmorillonite, waste of pinaceae plants, concentrated sulfuric acid, quick lime, polymeric aluminium phosphate and / or polyaluminium sulfate, and polymeric ferric sulfate. The multipurpose sewage treating agent is wide in raw material source and low in cost; the main raw material can be obtained through compounding the activated sludge of the urban sewage treatment plant, waste of pinaceae plants and acidized montmorillonite under the action of microwave, and then the main raw material is sequentially mixed with the quick lime, polymeric aluminium phosphate and / or polyaluminium sulfate, and polymeric ferric sulfate to obtain the efficient multipurpose sewage treating agent; the multipurpose sewage treating agent is simple in preparation technology and low in cost. When the multipurpose sewage treating agent is applied to treat sewage, the discharging quality of the treated sewage far exceeds the national first-class standard; in addition, the activated sludge at the bottom of a comprehensive treating pond of the urban sewage treatment plant can be used for preparing organic fertilizer, biomass fuel and / or the efficient multipurpose sewage treating agent.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a multipurpose 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 the world. Among ...
