Silt curing agent and production method thereof

Abstract

The invention discloses a silt curing agent and a production method thereof. The silt curing agent comprises the following components according to the following ratios: 18-20 parts of fluorite, 20-23 parts of sodium carbonate, 7-9 parts of quartz sand, 40-50 parts of gypsum, 10-12 parts of quick lime, and 6-8 parts of limestone. The silt curing agent disclosed by the invention can be used in the curing of silt or sludge with high water content from a sewage treatment plant, produced in industrial production or natural environment, and is also applicable to rapid setting and rapid hardening of cement slurry, high in curing strength, not easy to crack and good in strength durability, and the cured silt or cement is applicable to the machining of building products or directly used as a building material of civil engineering such as roads, dams and the like, thus being energy-saving and environment-friendly. Moreover, in the curing process of the sludge, certain volume expansion also can be generated, thus being conducive to the improvement of structure compactibility of the building products.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a sludge solidifying agent capable of using sludge as a renewable resource and a manufacturing method thereof. Background technique [0002] With the development of the national economy, environmental pollution is becoming more and more serious. Compared with the past, people have more urgent needs for environmental governance. However, with the diversification of industrial development, the sources of pollution are also more complicated. [0003] For example, in urban sewage, there are various sewage collected from residential buildings, units, schools, hospitals and public facilities drainage agencies. Sludge is an accessory of sewage treatment. Most of the components in sewage that cannot be filtered or digested are concentrated in the sludge. The sludge treatment process mainly includes concentration, dehydration, digestion, fermentation, drying ...

AI Technical Summary

Problems solved by technology

However, due to the complex composition of some sludge, or the destruction of the sludge composition structure in the post-treatment, it becomes unsolidified sludge

For this kind of sludge, because it is in a fluid state, it cannot be properly disposed of, and it is easy to flow with the water body, which will enlarge the pollution area; after the surface of the sludge is dry, the dust will float into the atmosphere and other hazards, so it needs a short time to make it The method of stabilization, sludge solidification agent is one of the products produced for this purpose

[0004] However, the effect of the sludge curing agent on the market is not ideal, the curing strength is low, and it cannot be directly used for sludge with high water content. Usually, the sludge needs to be treated to reduce the water content, and the process is complicated and the cost is high.
