Embodiment 1
[0025] The invention provides a sludge treatment method for wastewater biological treatment, the specific treatment steps are as follows:
[0026] Step 1. Separation of mud and water: the user can first use mechanical excavation to take out part of the sludge, and then use a fine grid to filter the remaining wastewater to separate the remaining sludge from the wastewater. The separated wastewater can be treated separately treatment process;
[0027] Step 2. Fermentation: Put the sludge separated from impurities in step 2 into the digester, and use microbial aerobic / anaerobic fermentation to digest it. The fermentation time is set to 10-15 days, and the sludge The feeding amount is less than 80% of the total volume of the digester. During anaerobic fermentation, the top of the digester should be covered with a cover. The cover is suitable for the inner cavity of the digester, and the cover is set as a steel floating cover. It can rise and fall with the liquid level in the pool...

[0033] The invention provides a sludge treatment method for wastewater biological treatment, the specific treatment steps are as follows:
[0034] Step 1. Separation of mud and water: the user can first use mechanical excavation to take out part of the sludge, and then use a fine grid to filter the remaining wastewater to separate the remaining sludge from the wastewater. The separated wastewater can be treated separately treatment process;
[0035] Step 2. Separation of sand and gravel: put the sludge separated in step 1 on the vibrating screen machine for screening, and the fluid sludge will be left along the sieve holes of the vibrating screen machine, while the large-diameter sundries or gravel The sieve remains on the top of the vibrating screen machine, and the user can use the waste water in step 1 to wash the separated sundries and gravel, and then use part of the clean water to wash, and the rinsing water and sewage are collected for centralized treatment. Can be rec...
