A method for increasing the effectiveness of an anaerobic filter bed, which prevents the accumulation of sludge and the generation of scum by providing gentle circulation to the anaerobic filter bed, and increases the number of times the contact material of the anaerobic filter bed comes into contact with wastewater, thereby increasing the effectiveness of the filter bed. Regarding.

し又沈澱して汚泥として槽内に堆積して行く。(B) Conventional technology Conventionally, in conventional wastewater treatment using activated sludge treatment, there is a sedimentation separation tank installed in front of the tank to separate the sediment in the wastewater and to make oil float to the surface.The flow of the wastewater is natural. Because of the flow, the filth that settles out of the sewage is partially decomposed by the anaerobic purification action, but most of it floats to the surface to form scum, and then settles and accumulates in the tank as sludge.

５０％を越えろとバキューム車等により搬出して槽容量

る場所に困る等二次公害を起こしていた。For this reason, when the floating scum and sediment exceed 50% of the effective capacity of the tank, the tank capacity is restored by removing it using a vacuum truck, etc., but this waste has a bad odor and it is difficult to find a place to dispose of it. It was causing further pollution.

減少しようとしている。Recently, the Ministry of Agriculture, Forestry and Fisheries and local governments have introduced anaerobic filter beds to these sedimentation separation tanks to increase the efficiency of sedimentation separation and purification as anaerobic treatment tanks, and to reduce the amount of waste generated by vacuum trucks. .

活動が減少する現状でこれの改善が広く望まれていた。However, in this method, the sedimentation separation tank is set up as an anaerobic treatment tank, and sewage is stored there for about one day, and the sewage is allowed to flow naturally, and anaerobic treatment is performed during this time. As this occurs, a portion of the filter media becomes clogged and its activity decreases, and there has been a widespread desire to improve this problem.

て環境衛生の向上を計らんとしたものである。(C) Problems sought to be solved by the invention As mentioned above, even if efficiency is improved by introducing a cut-edge anaerobic filter into the sedimentation separation tank placed in front of the aerobic activated sludge tank, the sewage produced by conventional natural flow still remains. In the case of inflow and discharge only, the frequency of disposal using a vacuum truck is only a little, and secondary pollution still remains and is unhygienic. Therefore, this should be significantly improved to increase the efficiency of anaerobic filter beds and improve environmental hygiene. This is an attempt to improve the situation.

Introducing an improved anaerobic filter material to help circulate sewage through the floor prevents sludge accumulation and scum, and improves purification efficiency by increasing contact between the anaerobic filter bed and sewage. The purpose of the present invention is to provide a method for increasing the effectiveness of an anaerobic filter bed.

気性ろ床の効力を格段と増進せしめるものである。(E) As a means to solve the problem, a filter bed equipped with an anaerobic filter material was introduced into the sedimentation separation tank placed in front of the aerobic activated sludge tank, and the sewage was collected by the conventional natural flow. The inflow and discharge are stopped, and a stirring device installed in the tank allows for gradual circulation of wastewater, thereby greatly increasing the effectiveness of the anaerobic filter bed.

する。(F) Effect When a stirring device is introduced into the sewage from a sedimentation separation tank equipped with an anaerobic filter bed to change the natural flow into a gentle circulation, the contact between the filter media and the sewage increases significantly, making the sewage anaerobic. Not only does the decomposition action of microorganisms progress and the generation of scum is reduced, but also the settled sludge is decomposed and its amount is drastically reduced, which not only eliminates secondary pollution such as conventional bad odors, but also dramatically reduces the number of times it is disposed of using a vacuum truck.
