With the increase of the difficulty of the current pollutant treatment and the continuous improvement of the emission standard, the anaerobic process is more and more emphasized and recommended due to the strong adaptability to high-concentration wastewater and high removal rate, the application is more and more extensive, and many industries increasingly select the anaerobic process as an important unit of a wastewater treatment system in the aspect of pollutant treatment.
The core of the anaerobic process is anaerobic sludge, and the quantity of the sludge directly determines the operation quality of the anaerobic process. After the anaerobic facility is built, anaerobic sludge needs to be added before the anaerobic facility is put into operation, and enterprises do not have anaerobic sludge, so that the anaerobic sludge needs to be purchased and transported back to be put into the anaerobic facility, the adding amount of the anaerobic sludge is very large, and if the anaerobic system can be quickly started, the added sludge amount reaches 80g/L, namely the sludge concentration in the anaerobic reactor averagely reaches 80kg/m3If the volume of the reactor is 1000m3And calculating, wherein the required amount of anaerobic sludge is 80 tons of absolute dry sludge, the required amount of anaerobic sludge is 800 tons converted into dilute sludge with the water content of 90%, the total cost of buying 1 ton of anaerobic sludge is 0.1 ten thousand yuan, and the cost of buying 800 tons is about 80 ten thousand yuan. Such high outsourcing costs are a significant cost burden for the enterprise. Meanwhile, strict requirements are also provided for what kind of sludge is purchased. Taking the paper making industry as an example, the purchased anaerobic sludge can be maximally ensured to adapt to a new environment and work normally after being pulled back under the conditions of the same type of paper mill, the same scale and the same water quality.
