Embodiment 1

[0030] see figure 1 with figure 2 , the present embodiment provides a sewage infiltration tank, including a treatment system and an aeration system 2 arranged sequentially from top to bottom, the treatment system is filled with crushed stones 10 and fine sand 11, and the particle size of the crushed stones is 3-3. 4cm, the gravel filling thickness is 10cm, the gravel filling rate is 60%, the fine sand particle size is 0.1-2mm, the fine sand filling thickness is 10cm, and the fine sand filling rate is 60%. The aeration system is composed of 5 parallel aeration pipes, a number of circular holes are arranged at intervals on the aeration pipes, and the circular holes are arranged facing upwards, and the aeration pipes are located at the bottom of the sewage infiltration tank and are continuous from bottom to top. Aeration leads to more dissolved oxygen in the lower layer of the percolation tank and less dissolved oxygen in the upper layer. At the same time, aeration is beneficia...

Embodiment 2

[0036] see Figure 4 with Figure 5 , the present embodiment provides a sewage infiltration tank, including a treatment system 1 and an aeration system 2 arranged sequentially from top to bottom, the treatment system 1 is filled with gravel 10 and fine sand 11, and the particle size of the gravel is 3-4cm, the gravel filling thickness is 50cm, the gravel filling rate is 40%, the fine sand particle size is 0.1-2mm, the fine sand filling thickness is 40cm, and the fine sand filling rate is 80%. The aeration system is composed of five parallel aeration pipes, the aeration pipes are located at the bottom of the sewage infiltration tank, and a number of round holes are arranged at intervals on the aeration pipes, and the round holes are arranged facing upward.

[0037] Preferably, the sewage infiltration tank of the present invention is also provided with a perforated water distribution pipe system above the treatment system 1, and the perforated water distribution pipe system con...

Embodiment 3

[0041] see Image 6 , This embodiment provides a sewage infiltration system, including the primary sedimentation tank 9 and the sewage infiltration tank in Embodiment 1. Sewage first passes through the primary sedimentation tank 9 to remove sinkable and floating matter, and then sprays it evenly on the gravel filler through the nozzle to make a layer of uniform biofilm grow on the filler. An aeration system is installed at the bottom of the sewage infiltration tank to continuously aerate The gas provides sufficient dissolved oxygen, and the oxygen fully contacts the sewage flowing downward from bottom to top, which improves the degradation rate of pollutants in the sewage, and finally the treated sewage flows out through the drain.

Abstract

A wastewater percolation tank and a wastewater percolation system are disclosed. Broken stone the specific surface area of which is large is adopted as a filler layer of the system, thus increasing the contact area between wastewater and a biomembrane and increasing the wastewater treatment efficiency. The wastewater percolation tank and the wastewater percolation system have characteristics of low energy consumption, good nitrogen removing and phosphorus removing effects, a low construction cost, convenient management and operation, a low treatment cost, and the like. The bottom of the wastewater percolation tank is provided with aeration pipes to supply sufficient dissolved oxygen for the equipment, thus increasing the pollutant degradation rate.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage percolation pool and a sewage percolation system. Background technique [0002] At present, sewage dripping filtration system and biological filter are mainly used to treat sewage. The traditional sewage dripping filtration system has low operating costs and low investment, and due to the use of natural ventilation system, the effect of effluent water quality is average, especially for the treatment of ammonia nitrogen. Traditional The current biological aerated filter adopts a submerged biological filter. The biggest disadvantage is that it needs to overcome the water pressure and consume a lot of power. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sewage percolation tank and a sewage percolation system, which can overcome the problems of poor sewage treatment effect and large power consumption in the ex...
