Abstract

The invention provides a soil conditioner which comprises the following components by weight percentage based on the dry basis, 70-90% of ammonibacteria sludge, 0.1-10% of active ingredients and 5-25% of accessory. The invention also provides a preparation method for the soil conditioner and an application. By ammoniating the soil, the invention increases the nutrient content of the soil conditioner and simultaneously turns the sludge and organic material which pollute or harm the environment into a resource, thus not only solving the handling problem of waste, improving the environment, recycling the waste and opening up a new approach to the raw material required by the production of the soil conditioner.

Description

technical field [0001] The invention relates to a soil conditioner, in particular to a soil conditioner with sludge as raw material, its preparation method and application. Background technique [0002] Water and soil erosion leads to siltation of rivers and lakes, which needs to be cleaned up in time. If it can be fertilized, it can come from the field and return to the field, which is a great supplement to the fertility of the land. A large amount of organic matter deposited in rivers and lakes has caused eutrophication of the water body, resulting in a large amount of aquatic organisms that need to be removed. At the same time, with the improvement of people's living standards, more and more various types of garbage are produced that need to be disposed of. [0003] As for whether there is any harm in the agricultural storage of sludge, and how much harm is there, there are many studies in this area. Lin Lanwen et al. "Municipal Sewage Sludge Mixed with Straw and Fly Ash ...
