With the development of economy, the intensification degree of industry and agriculture is higher and higher, and the solid waste generated by the intensification degree has the characteristics of multiple types, large quantity and concentration, wherein the urban domestic sludge occupies a considerable portion and is one of the main pollution sources of the ecological environment. According to statistics, the yield of wet sludge (with water content of 80%) is more than 1 hundred million tons every year in the world, the annual yield of sludge in China is about 800 million tons dry weight (converted into wet sludge cake of about 3200 million tons), the yield is increased at a speed of 10-15% every year, most of the sludge is simply piled up or randomly discarded, the effect of purifying the environment of a sewage treatment plant is greatly counteracted, the healthy development of the sewage treatment industry is seriously restricted, and how to treat organic solid waste which is increasingly huge in quantity and continuously generated every day becomes a great social problem to be solved urgently.
The town sludge is a great environmental pollution source and a huge biomass resource and energy bank. Organic matters, pathogenic bacteria, heavy metals and the like in the sludge can cause pollution to the environment without treatment, but the sludge after proper treatment can achieve the purposes of reduction, harmlessness and reclamation. The sludge contains rich nitrogen, phosphorus, potassium and other nutrients indispensable to the growth of plants and crops, and the treated sludge reaching the standard can be used for agriculture to improve soil; the sludge can be used as organic fertilizer, so that the harmless treatment and resource utilization of the municipal sludge and solid waste are the requirements for implementing the national relevant environmental protection policy and urban development, the problem that the sludge is increasingly serious can be better solved, the secondary pollution of the sludge is prevented, the ecological environment is protected, the sludge treatment work in China is promoted, and the development of the environmental protection industry is promoted. Therefore, we propose a nutrient soil for landscaping seedling planting to solve the above problems.
