Embodiment 1

[0097] Example 1: A pit type high temperature aerobic biological fermentation deodorizer, with a daily treatment of 430m 3 Take organic waste as an example. First, set up two adjacent pits, which are the first biological fermenter and the second biological fermenter. The length is 53m, the width is 15m, the wall height is 2.25m, and its bottom surface is 3 meters above the ground. , to prevent rainwater from pouring back, and dozens of ventilation and oxygen supply ditches 5 are arranged on the bottom surface, and each ventilation and oxygen supply ditch is equipped with 50 ventilation and oxygen supply pipes 6, and the two ends of the ventilation and oxygen supply pipes 6 are connected to the inner sides of the walls 9A and 9B on both sides. The layout is 100mm wide, 400mm high, and 50m long. The rectangular main air ducts 4A and 4B are connected. The main air ducts are respectively connected to two fans 4C. The fan power is 11KW and the air volume is 15000m 3 / h, wind press...

[0129] Embodiment 2: A pit type high temperature aerobic biological fermentation deodorizer, with a daily treatment of 430m 3 Take organic waste as an example. First, set up two adjacent pits, which are the first biological fermenter and the second biological fermenter. The length is 53m, the width is 15m, the wall height is 2.25m, and its bottom surface is 5 meters above the ground. , to prevent rainwater intrusion. Dozens of ventilation and oxygen supply ditches 5 are arranged on the bottom surface, and each ventilation and oxygen supply ditch is equipped with 150 ventilation and oxygen supply pipes 6. The 50m-long rectangular main air ducts 4A and 4B are connected, and the main air ducts are respectively connected to two fans 4C, with a fan power of 40KW and an air volume of 50,000m 3 / h, the wind pressure is 2500Pa, and the fans are used to ventilate and supply oxygen to the main air pipe 4 respectively. The fans are controlled by the PLC computer and the frequency conve...

Embodiment 3

[0160] Example 3: A method for degrading the stench of organic malodorous waste using a pit-type mesophilic aerobic biological fermentation deodorizer, with a daily treatment of 430m 3 Taking organic waste as an example, first, set up the above-mentioned biological fermentation deodorizer, the specific steps are as follows:

[0161] (1) The dump truck will use the potential difference from the elevated road to unload the biologically pretreated materials directly onto the bottom surface of the fermenter, pile them up along the wall into a 0.4-1.2m high oblique triangle pile, and unload the materials one by one , until it is full; or use a dump truck to directly drive into the bottom surface of the first biological fermenter, and unload and pile up into strips one by one;

[0162] (2) Divide the biological fermenter into three sections, the first section is 0-4m, the second section is 4-7.6m, the third section is 7.6-10.8m, and the bucket and arm length of the special compostin...

Abstract

The present invention relates to one kind of underground silo type high temperature aerobic biofermenting deodorizer and its method of degrading organic stench waste compost. The underground silo has ventilating pipes connected to one main ventilating pipe in the bottom, and water filtering ditches communicated to ventilating ditches separately. The organic stench waste is decayed to form compost in the underground silo through the first biologically pre-treatment in the underground silo for 5-8 days and the secondary fermenting in a secondary fermenting unit for 12-28 days. The present invention can obtain compost with rich humus and no bad smell.

Description

technical field [0001] The invention belongs to the field of biological fermentation, namely an aerobic biological deodorizer and a biodegradation method, in particular to a pit-type high-temperature aerobic biological fermentation deodorizer and a method for degrading organic malodorous waste compost. Background technique [0002] my country's malodorous waste organic matter is processed in a large amount and covers a wide range, especially the malodorous waste that greatly affects the ecological environment, such as human and livestock manure, domestic garbage, sludge, industrial waste residue, industrial biomass waste, catering waste, etc. A large number of straws have become a major problem of environmental pollution in our country. [0003] In my country, livestock and poultry manure, domestic garbage, and urban domestic sludge, not including industrial sludge, industrial waste residue, and industrial filter sludge, have become the three major sources of odor pollution. ...
