Village and town sewage treatment apparatus

Abstract

The invention provides a village and town sewage treatment device, which includes an anaerobic pool, an aerobic pool, a sedimentation tank, filter material, adsorption filler, and a sludge concentration tank. The position is set so that the water body can be disturbed. The aeration pipeline at the bottom of the aerobic tank has flow holes. The air bubbles float up and cause the water body to roll up and down. The setting plays the role of reinforcing ribs to prevent the deformation of the tank body due to water pressure, and at the same time slow down the water speed to fully complete the aerobic reaction; the diffuser cap at the outlet of the sedimentation tank inlet pipe is conducive to the entry of wastewater into the sedimentation The pool is evenly distributed, and combined with the inverted rectangular platform shape of the sludge hopper of the sedimentation tank and the surrounding water outlet weirs above, the operation of the sedimentation tank is optimal; the overflow pipe and backwashing structure are set to make the system run simply and efficiently .

Description

technical field [0001] The invention relates to a village and town sewage treatment device, which is applied to the treatment and disposal of distributed village and town sewage. Background technique [0002] With the increase of population, the accelerated process of urbanization and the implementation of the total control measures of industrial point source pollution, residential pollution will gradually replace industrial pollution as the number one pollution factor of water bodies. Centralized sewage treatment is undoubtedly the right choice for urban high-level network collection coverage, but in villages and towns, the centralized pipeline network cannot be reached, and even if it can be extended along the main road, the connection costs and long-distance sewage pumping station transportation and operating costs are very high.

Problems solved by technology

Centralized sewage treatment is undoubtedly the right choice for urban high-level network collection coverage, but in villages and towns, the centralized pipeline network cannot be reached, and even if it can be extended along the main road, the connection costs and long-distance sewage pumping station transportation and operating costs are very high. High, the waste water is naturally infiltrated in the soil in front of the house and behind the house, and the feces are stored in various septic tanks for local treatment, which seriously pollutes the environment and greatly increases the cost of sewage treatment per unit

On the other hand, the environmental protection of villages and towns has been neglected for a long time, and the pollution of domestic water in villages and towns has become more serious. With the continuous advancement of new villages and towns, the problem of water pollution in villages and towns has become increasingly prominent, which not only seriously affects and restricts the development of agriculture, farmers' income and rural areas. Moreover, it has had a relatively large negative impact on the living environment, economic and social development of the vast villages and towns, and has become an important restrictive factor for the construction of new villages and towns.

The existing village and town sewage treatment equipment and equipment are expensive, and the treatment cost-effectiveness is low, so it is difficult to implement in villages and towns
