Problems solved by technology

Large investment, high energy consumption, small processing capacity and high cost
[0012] 7) Sludge-based adsorbent technology, that is, municipal sludge is activated and modified by high-temperature pyrolysis to produce carbon-containing adsorbents. This technology is currently in the laboratory stage, and there are obviously potential high energy consumption and hidden dangers of secondary pollution
[0014] For this reason, there is an urgent need for an organic matter that can effectively improve the muddying (that is, being penetrated and structurally covered by the inorganic matter-mudgy components in the sludge and silicified / aluminized) in the sludge, and Modification and adjustment agent for the combustion characteristics of the organic matter of bacterial mass with high internal water, so as to solve the dilemma of resource utilization and energy utilization of sludge as a renewable energy

Abstract

The invention discloses a modification regulator for sludge energy regeneration. The modification regulator comprises an oxidization nitrating agent, wherein the oxidization nitrating agent is a substance capable of improving the combustion performance of argillation organic matters and highly internal water zoogloea organic matters in sludge; and the modification regulator is prepared by uniformly mixing a strong oxidant and nitrate in the proportion of (20-70): (80-30), or the modification regulator in the form of paste, solution or suspending liquid is prepared by mixing the strong oxidant and the nitrate in the proportion of (20-70): (80-30), adding water and uniformly stirring. According to the modification regulator, oxidation nitration is carried out on organic matter combustible materials taking the argillation organic matters and highly internal water zoogloea organic matters in sludge as main matters by using the modification regulator, so that the fuel performance of the sludge can be effectively improved, and the modification regulator is beneficial for the recycling energy utilization of sludge.

Description

technical field [0001] The invention relates to the field of environmental protection materials, in particular to a sludge energy modification regulator. Background technique [0002] With the acceleration of urbanization in our country, the output of municipal sewage and sludge has increased dramatically. In 2006, my country's urban domestic sewage discharge was 29.66 billion tons. By 2012, the domestic sewage discharge had reached 46.27 billion tons, with an average annual compound growth rate of 7.69%. [0003] As of the beginning of 2015, a total of 3,892 municipal sewage treatment plants have been built in cities and counties across the country, with a sewage treatment capacity of about 176 million cubic meters per day, and their municipal sludge output has exceeded 30 million tons. [0004] Municipal sewage treatment plants produce municipal sludge with a large amount of pollutants in the process of treating urban domestic sewage and industrial wastewater. The moistur...
