Sewage treatment apparatus

Abstract

The invention discloses a sewage treatment apparatus. The apparatus comprises a pontoon raft body, an electricity generation and storage system, a pneumatic source, a direct current motor, combined packings and a liftable aeration system, the electricity generation and storage system comprises solar cell panels, an aerogenerator and a battery pack, the pontoon raft is fixedly provided with a support, the battery pack is arranged in the support, the periphery of the support is provided with the solar cell panels, the aerogenerator is arranged in the middle of the support, the combined packings are arranged below the pontoon raft body, and the liftable aeration system is arranged at the bottom of the pontoon raft body. The solar cell panel and the aerogenerator provide energy, direct current is inverted to alternating current to promote the direct current motor to drive the pneumatic source to work in order to generate airflow, and airflow is introduced to aeration tubes under the water surface, so the packings in water and the water surface besieged by floating bodies undergo a biochemical reaction under the aeration action of air in the aeration tubes to become a hotbed for various fungi and algae. The apparatus has the advantages of low energy consumption, low cost, unattended operation, massive production, random arrangement and large sewage treatment capacity.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a sewage treatment device. Background technique [0002] At present, sewage treatment is a major challenge facing our country. The proportion of water quality sections below Grade III in my country's top ten river basins is nearly 30%. At the same time, a large amount of domestic sewage in rural areas is difficult to be treated in the same way as in cities. In the end, most of the domestic sewage in rural areas is directly discharged into various rivers in densely populated villages, resulting in widespread pollution of rural rivers. [0003] At the same time, the activated sludge method commonly used in sewage treatment currently occupies a large area, consumes a lot of energy, requires a large amount of professional equipment, requires large-scale infrastructure construction, and requires reprocessing of the generated sludge. The activated sludge method has a single strain of bacter...

Problems solved by technology

At the same time, a large amount of domestic sewage in rural areas is difficult to be treated in the same way as in cities. In the end, most rural domestic sewage is directly discharged into various rivers in densely populated villages, resulting in widespread pollution of rural rivers.

[0003] At the same time, the activated sludge method commonly used in sewage treatment currently occupies a large area, consumes a lot of energy, requires a large amount of professional equipment, requires large-scale infrastructure construction, and requires reprocessing of the generated sludge. The activated sludge method has a single strain of bacteria. The ecological chain is weak, prone to shortcomings such as sludge bulking

It is doomed that it is impossible to meet the needs of rural domestic sewage treatment and river management all over the country
