Urban and rural sewage treatment agent, and preparation method thereof

Abstract

The invention discloses an urban and rural sewage treatment agent. The urban and rural sewage treatment agent consists of the following raw materials in parts by weight: 5 to 12 parts of a sodium silicate solution with the mass percentage of 12 to 18 percent, 3 to 8 parts of water hyacinth, 2 to 6 parts of reed, 5 to 10 parts of alum, 10 to 16 parts of diatomite, 6 to 15 parts of nanometer bentonite, 2 to 8 parts of lithopone, 1.5 to 6 parts of coal ash, 7 to 18 parts of graphite and 4 to 8 parts of sweet-scented osmanthus, wherein the lithopone is a mixture of zinc sulfide and barium sulfate. The invention also discloses a preparation method of the treatment agent. The raw material source is wide, the preparation process is simple, and the treatment agent is convenient to use and suitable for popularization and industrialized production; the prepared product is non-toxic and pollution-free, the raw materials are low in price and high in selectivity, significant effects of reducing the cost of a sewage treatment plant and improving the sewage treatment quality are achieved, and influence on the surrounding environment is avoided.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an urban sewage treatment agent. 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. [0003] In the annual sewage discharge in the country, only 10% of domestic sewage and 70% of industrial sewage are treated, and the effluent of about half of the sewage treatment facilities doe...

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 or semi-stop production for a long time due to high energy consumption. Energy consumption problems Will become the bottleneck of urban sewage treatment
