Abstract

The invention belongs to the technical field of novel fertilizers, and particularly relates to a granular organic fertilizer prepared from sludge. The fertilizer is prepared from the following components in parts by weight: 46-60 parts of dried sludge, 10-12 parts of animal waste, 3-5 parts of an active microbial agent, 10-12 parts of rice hull powder, 7-9 parts of oxidized starch clay, 4-6 partsof durian shell-shaddock peel powder/allyl succinic anhydride/hyperbranched polyamidoamine (HBPNH2) and 6-10 parts of xanthan gum multi-grafted paraffin emulsion. The invention further provides a preparation method for preparing the granular organic fertilizer from the sludge. The granular organic fertilizer prepared from the sludge disclosed by the invention has remarkable technical effects of adsorbing heavy metals and coating a protective layer.

Description

technical field [0001] The invention belongs to the technical field of new fertilizers, in particular to a granular organic fertilizer made from sludge and a preparation method thereof. Background technique [0002] With the development of my country's economy and urbanization, urban sewage continues to increase, and a huge amount of sludge is produced after sewage treatment. If a large amount of sludge cannot be fully and effectively treated and utilized, serious secondary pollution problems will inevitably occur, such as stench, Parasites, organic matter, etc. pollute water sources. Therefore, how to scientifically treat and utilize sludge and turn waste into treasure is an urgent problem to be solved after sewage treatment in our country. Sludge is rich in nitrogen, phosphorus, potassium and other plant nutrients and rich organic matter, which can be used as organic fertilizer to improve the physical and chemical properties of the soil and increase the yield of crops. Th...
