Problems solved by technology

However, during this process, the malodorous source continuously releases malodorous gases such as ammonia, hydrogen sulfide, and organic amines. Due to the pressure of environmental protection, the responsible unit needs to continuously spray deodorizing liquid, resulting in a large amount of deodorizing operation costs.
Secondly, such pollution sources often contain toxic and harmful substances. In case of rainfall, the pollutants can seep out with the rainwater and produce secondary polluted wastewater, which is likely to pollute the soil and groundwater.
In addition, such pollution sources are prone to produce dust, dust and other particles and other sundries, which seriously pollute the atmosphere and the ecological environment.

Abstract

The invention relates to a spray covering process of solid pollution sources. The solid pollution sources include refuse landfills, sludge stockpiling sites, industrial waste stacking sites, mineral tailings ponds or solid pollution sources formed by contaminated sites. The spray covering process includes the steps that a curing base material, a curing agent and a solvent are mixed to form a highviscosity paste composite material, and the surfaces of the solid pollution sources are covered by uniform spraying of spraying equipment. According to the spray covering process, diversion of rain and sewage from solid pollution source piles or sites is realized, sewage generation caused by rainwater mixing is reduced remarkably, and safety of soil and groundwater in stacking sites is ensured; meanwhile according to stink source piles, the odor isolation (deodorization) effect is good, and friendly environment is achieved; and furthermore, the functions of fire prevention, dust prevention andseepage prevention are achieved, application is wide, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of pollution source treatment, in particular to a spray covering process for solid pollution sources. Background technique [0002] Unorganized discharge pollutants such as malodorous gas, dust, and waste liquid produced in industrial production and life have become important factors affecting health, work, life, and the environment, and are also important control indicators for environmental protection standards for enterprises in various industries. Solid pollution sources such as industrial waste, municipal sludge, domestic garbage, tailings ponds, and exposed ground in contaminated sites are the main sources of foul-smelling gases, black and smelly water bodies, and flying dust. Due to insufficient disposal capacity or cost savings, such pollution sources usually need to be temporarily stored, accumulated and then disposed of in a unified manner. However, during this process, the malodorous source conti...
