[0093] use figure 1 (However, 170 is the discharge port, 180 is the input port, and a single-shaft screw pump and a decompression pump are installed at the rear of the discharge port to replace the decompression unit of 190) to treat excess sludge with a cell wall or cell membrane crushing device . The processing condition is that the number of revolutions of the rotating disk is 3500min- 1 , the peripheral speed is 50m / s, the pressure reduction condition is -0.01MPa, and the processing time is 60 minutes. In order to reproduce the anaerobic treatment routinely employed in the field of sewage treatment, a batch test using vials was employed. Anaerobic treatment refers to a biological process in which organic substances contained in sludge are degraded and converted into methane gas through the metabolic action of microorganisms such as methane bacteria under anaerobic anaerobic conditions.

[0100] The actual anaerobic treatment takes place continuously. Therefore, in order to carry out a model test of continuous anaerobic treatment, a digester that mixes digested sludge and substrate (excess sludge before treatment with a cell wall or cell membrane disruptor or excess sludge after treatment) and performs anaerobic treatment is used. A test device consisting of a bottle and a produced gas detector that collects the produced gas on the water surface. = 1.5 L of digested sludge as seed sludge was put into a digester bottle (2 L) whose interior was substituted with nitrogen. The operating conditions in the continuous biodegradability test are shown in Table 1. In addition, the digested sludge and substrate used in each operating condition are shown in Table 2. Digested sludge generated from the digestion flasks was sampled daily in the amount reported in Table 1. After sampling, the same...

[0114] The experimental device for aerobic treatment consists of both an aeration tank and a sedimentation tank. Glucose, which is the input mechanism of the main carbon source, was supplied to the aeration tank under the condition that the inflow BOD was about 200 mg / L. Regarding the operating conditions, the activated sludge put into the aeration tank is 20L, the residence time is 24 hours, and the MLSS in the aeration tank is set at 1,000-2,000mg / L. The days of consecutive trials were 20 days. After concentrating the excess sludge generated in this process, the thing treated with the cell wall or cell membrane crushing device is returned to the aeration tank, and the amount of excess sludge generated, as well as the water quality in the aeration tank and the treated water are studied. The treatment conditions of the cell wall or cell membrane disruption device were implemented under the same conditions as in Example 1. The result is in Figure 6 , shown in Table 4 and Ta...
