Embodiment 1

[0033] Embodiment 1: A method and process for utilizing sludge and woody waste mixed bioenergy, comprising the following steps:

[0034] S1. Raw material pretreatment: raw material pretreatment includes the following steps: S10, sludge dehydration; S11, crop straw crushing; S12, wood waste removal for building decoration; S13, high-temperature drying of feces; S14, cinder crushing;

[0035] S10. Sludge dehydration: spread the above 30 kg of sludge in the sun (the height of the paving is 5 cm) to make it evenly dehydrated. After 2 days of continuous drying, keep the moisture content at 40%, and pack it into a box for later use;

[0036] S11. Crushing of crop stalks: Gather the above 20 kg of crop stalks together, and then send them into a pulverizer for crushing. The length and width of the crushed straw should not exceed 2 cm. The purpose is to be able to mix with other materials evenly. , and then put it in a ventilated place to dry for 3 days, then put it in a box for later ...

Abstract

The invention discloses a sludge and wood waste mixed biological energy source. The sludge and wood waste mixed biological energy source is composed of the following components in parts by weight: 30-60 parts of sludge; 20-40 parts of crop straw; 10-20 parts of wood waste for building decoration; 5-10 parts of excrement; and 5-10 parts of coal slag. The invention belongs to the technical field ofbiological energy, and relates to a sludge and wood waste mixed biological energy utilization method and a process thereof, which effectively solve the problems of industrial and domestic sewage precipitation, sludge and straw storage difficulty, transportation difficulty, digestion difficulty and air pollution caused by combustion in the agricultural production process. According to the method, abiocatalyst yeast and cell enzyme composite binding agent which is independently researched and developed is adopted, and the method is a new energy technology for efficiently utilizing industrial and agricultural domestic sewage, sludge, agricultural straw and wood waste for building decoration for full fermentation.

Description

technical field [0001] The invention relates to the technical field of bioenergy, in particular to a method and a process for utilizing bioenergy mixed with sludge and wood waste. Background technique [0002] In our life, all kinds of garbage and waste are spread all over the city. First, urban sludge contains a large amount of organic substances, heavy metals, pathogenic bacteria and other toxic and harmful substances. Improper disposal will cause secondary pollution to the environment. If there is no normal and stable treatment and disposal channel, the sludge problem will become the bottleneck of sewage treatment. Second, in my country's agricultural areas, the treatment of straw after harvest has been criticized, and the burning of straw has caused great pollution to the environment. Third, real estate is currently a pillar industry in my country. The construction waste used for real estate construction has also been criticized for its treatment method. The direct fill...
