Embodiment 1

[0035]Put the solid domestic waste into the oblique flow washing and sorting tank, and use two 200 cubic meters of soaking and dissolving washing and sorting tanks alternately, soak for 30 to 36 hours, so that the soluble organic matter in the domestic solid waste can be dissolved in water and sorted out Non-degradable inorganic matter and suspended organic matter. Put the suspended organic matter into the grid screening machine to sort out non-degradable and degradable organic matter. Put the sorted organic matter into an organic matter pulverizer to pulverize, and settle in the grit chamber for 1 hour. Put the desanded organic matter into the grid screening machine for the second screening, sort and recycle the non-degradable organic matter plastics, fibers and films, and send the degradable organic matter food residue, vegetable leaves, fruit peels and weeds into hydrolysis conditioning pool. Add the hydrolysis regulator EM bacteria, control the addition of hydrolyzate: E...

Embodiment 2

[0037] Put the solid waste from the market into the oblique flow washing and sorting tank, and use two 150 cubic meter soaking and dissolving washing and sorting tanks alternately, soak for 25 to 30 hours, so that the soluble organic matter in domestic solid waste can be dissolved in water and sorted out Non-degradable inorganic matter and suspended organic matter. Put the suspended organic matter into the grid screening machine to sort out non-degradable and degradable organic matter. Put the sorted organic matter into an organic matter pulverizer to pulverize, and settle in the grit chamber for 1 hour. Put the desanded organic matter into the grid screening machine for the second screening, sort and recycle the non-degradable organic matter plastics, fibers and films, and send the degradable organic matter food residue, vegetable leaves, fruit peels and weeds into hydrolysis conditioning pool.

Abstract

The invention discloses a processing method for the comprehensive utilization of solid household refuse, which comprises the following steps: hydrolyzing solid household refuse; classifying and sorting based on the different specific gravities of the refuse in water; crushing, screening, and separating out solids, liquids and gases by using an active internal circulation (TAIC) anaerobic reactor; preparing energy, environment friendly bricks, organic biological fertilizers and other products, and recycling nondegradable organic substances and metals; using return water as water for the production process and industrial / agricultural water to produce marsh gas energy for generating power for production or living use; and using the excess heat from power generation for regulating the temperature in a hydrolysis regulation tank and as a heat source for living. Thus, the processing method in the invention realizes the reclamation, the harmlessness and the circular economy of the solid household refuse. Besides, the complete set of processing equipment has the advantages of low investment, low operating cost and small occupied area, the occupied area does not need to be increased every year, and the yield is larger than the investment. Therefore, the processing method in the invention can be easily popularized and used.

Description

Technical field: [0001] The invention belongs to the technical field of domestic waste treatment, and relates to a method for hydrolyzing three separations and anaerobic treatment of solid domestic waste, in particular to a treatment method for comprehensive utilization of solid domestic waste. Background technique: [0002] With the development of the economy and the improvement of people's living standards, the output of garbage is also increasing rapidly. The annual output of garbage in my country is about hundreds of millions of tons, which seriously endangers the environment. At present, domestic and foreign domestic waste treatment methods are mainly: [0003] 1. Landfill method: Choose a suitable place to bury the garbage in the ground, and some also set up pipelines to lead out biogas for power generation. This treatment method not only takes up valuable land resources, but also the landfill leachate will pollute the groundwater and soil again; [0004] 2. Composti...
