Problems solved by technology

Among them, separate incineration is not suitable for projects with a small scale of sludge, and sludge incineration was once very popular. However, sludge incineration has a large one-time investment, high equipment investment, high operating costs, and the combustion temperature of organic matter is lower than 850. At ℃, dioxin and other highly toxic substances are produced, and the flue gas needs to be treated, and the incineration ash needs to be reprocessed, which limits its use.
[0006] In addition, in the existing domestic and foreign sludge treatment methods, the drying mostly adopts the form of thermal drying and composting. Although methods such as optimizing heat sources, reducing process steps, and optimizing operating parameters have been adopted to reduce energy consumption, due to The use of external heat sources limits the development of thermal drying processes

Abstract

The invention discloses a proteus mirabilis preparation for treating domestic sludge, and a preparation method and application thereof, belonging to the technical field of domestic sludge treatment. The proteus mirabilis preparation is prepared by culturing the proteus mirabilis by mixing the wormcast extracting solution and other nutritional ingredients, and then the proteus mirabilis preparationis sprayed into the domestic sludge to treat the sludge, the moisture content of the treated sludge can be reduced to 30-50%, the reduction and harmless are obvious, and the fertilizer preparation and the soil conditioner requirements are satisfied.

Description

technical field [0001] The invention belongs to the technical field of domestic sludge treatment, and in particular relates to a preparation of Proteus mirabilis for treating domestic sludge, a preparation method and application thereof. Background technique [0002] The disposal and treatment technology of municipal domestic sludge has always been a problem that hinders the development of cities. With the development of urbanization and the continuous increase of urban population, the discharge of industrial wastewater and domestic sewage is increasing. The annual sewage discharge in my country has reached 18 trillion cubic meters. Calculated at 0.3% to 0.5%, the production amount also reaches tens of millions of tons. At present, most large and medium-sized cities in China, including Chengdu, Shanghai, Guangzhou, and Beijing, are facing the situation of no land to bury, which is one of the most prominent problems faced by urban construction and environmental protection in ...
