First, the color of the fermentation liquor turns yellow
1. Reasons for acidification of fermentation raw materials
2, processing methods
(1) When the fermentation pH is not lower than 6. Additional inoculum or fermentation broth in normal gas pools can be added to the digester.
(2) When the oH value of the fermentation liquid is less than 6. Then need to remove 1/3 of the fermentation broth, first add the inoculum or add lime water or ash to adjust the pH value to about 6.5, then add the inoculum or fermentation broth of the normal gas pool.
Second, the new pool does not produce gas after startup
1, the reason
(1) The added raw materials and sewage are supercooled.
(2) Toxic substances are mixed when feeding.
(3) Leakage from biogas digesters or gas transmission systems.
2, processing methods
(1) Take out the supercooled liquid and re-feed when the temperature is higher.
(2) Remove all toxic liquids and re-feed. (3) Check the cause of the leak, repair or replace it.
Third, there is gas but can not be ignited
1, the reasons for the lack of methanogenic inoculants,
2, processing methods
(1) Pause feeding.
(2) Supplementation of methanogenic activated sludge or organic sewage.
Fourth, suddenly not producing gas
1, the reason
(1) There is a crack in the digester and gas transmission system.
(2) Insecticides such as pesticides were mixed in the feed. (3) Mixed with strong oxidants.
2, processing methods
(1) Check the leaks and repair and replace them in time.
(2) Remove the original fermentation material and re-feed.
5. There are many fermentation raw materials but insufficient gas production
1, the reason
(1) The input raw material temperature is too low,
(2) The input of raw materials is too old.
(3) The fermentation broth is too concentrated and acidified.
(4) Lack of methanogenic inoculants.
2, processing methods
(1) Take out the too cold, too old fermentation liquid and re-feed.
(2) Stop feeding, supplement inoculum or sewage.
Sixth, the pressure gauge rises quickly
1, the reason
(1) The pressure between the digesters is too small.
(2) There is a blockage in the air tube or air tube or the tube diameter is too small.
(3) There is too much fermentation liquid in the digester.
2, processing methods
(1) Expand water pressure according to design requirements.
(2) Clear the blockage.
(3) Replace the larger diameter gas pipeline.
(4) Remove some of the fermentation material liquid.
Seven, high pressure but no firepower
1, the reason
(1) Methane content in biogas is too low.
(2) There is a blockage in the cooking nozzle or fire tray.
2, processing methods
(1) Supplement the biogas inoculum.
(2) Clean the stove nozzle or fire plate plug.
Eight, pressure gauge pointer instability
1, the reason gas pipeline water,
2. Treatment method Install the water collector at the lowest part of the gas pipeline and drain the water regularly.
IX. Biogas lights are off or dark
1, the reason
(1) The methane content in biogas is low.
(2) The nozzle is clogged.
(3) There is water in the gas pipeline.
(4) The yarn cover is not matched.
2, processing methods
(1) Inoculate the biogas tank with inoculum.
(2) Clear nozzle clogging.
(3) discharge water pipe water.
(4) Replace the yarn cover.
Ten, pressure gauge pressure can only rise to a certain height
1, the reason
(1) The digester gas tank has a slight leak.
(2) Leakage of biogas digesters.
2, processing methods
(1) Check for leaks and leaking parts and repair them promptly.
(2) Check the gas system for leaks, sand holes or cracks, and re-bond or replace.
