Abstract

The invention discloses an efficient multi-purpose sewage treatment agent and a sewage treatment method utilizing the same. The efficient multi-purpose sewage treatment agent is prepared from the following raw materials: municipal sewage plant active sludge, smectite, pinaceae plant wastes, concentrated sulfuric acid, calcined lime, poly aluminum phosphate and/or poly aluminum sulfate and poly ferric sulfate. The efficient multi-purpose sewage treatment agent is wide in raw material source and low in cost. The efficient multi-purpose sewage treatment agent is prepared by compounding the municipal sewage plant active sludge, the pinaceae plant wastes and the acidified smectite under the action of microwaves to obtain a main raw material and then sequentially mixing the main raw material with the calcined lime, poly aluminum phosphate and/or poly aluminum sulfate and poly ferric sulfate. The efficient multi-purpose sewage treatment agent is simple in preparation process and low in cost; when the efficient multi-purpose sewage treatment agent is applied to treating sewage, the discharge quality of treated sewage is far superior to the national primary standard; the municipal sewage plant active sludge at the bottom of a comprehensive treatment pool can be used for preparing organic fertilizers, biofuels and/or the efficient multi-purpose 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 ...
