Batch water inlet and continuous water outlet sewage treatment device and treatment method

Abstract

The invention discloses a batch water inlet and continuous water outlet sewage treatment device and treatment method. The device comprises a water inlet adjusting buffer area, an anaerobic adjusting reaction area, an anoxic adjusting reaction area and an aerobic membrane reaction area which are sequentially arranged along a water flow direction, the anoxic adjusting reaction area is provided witha sewage lift pump, the sewage lifting pump is respectively communicated with a water inlet adjusting buffer area and the aerobic membrane reaction area through a first pipeline, the aerobic membranereaction area is provided with a sludge reflux pump and an MBR membrane assembly, and the sludge reflux pump is respectively communicated with the water inlet adjusting buffer area and the anoxic adjusting reaction area through a second pipeline. According to the invention, the problem of extremely non-uniform sewage discharge amount can be effectively solved without independently arranging an adjusting tank, enhanced nitrogen and phosphorus removal is realized at the same time, and the device has the advantages of simple treatment unit, small floor area and good water outlet effect.

Description

technical field

[0001] The invention belongs to the technical field of sewage treatment, in particular to a sewage treatment device and treatment method for batch water inflow and continuous water outflow. Background technique

[0002] With the development of the economy, large-scale comprehensive activity venues are gradually increasing, and the flow of people is also increasing. A certain amount of sewage will be produced during the operation of such places, mainly including toilet flushing water, catering industry sewage, and a small amount of ground flushing water and cleaning water. Among them, toilet flushing water and catering industry sewage are the main sources of sewage. Compared with urban domestic sewage, its content of COD, ammonia nitrogen, total nitrogen, and total phosphorus is higher, and it also contains a certain amount of surfactant substances, which is difficult to treat. Slightly more difficult than urban sewage. At present, most large-scale office bu...

Examples

Embodiment 1

[0025] Please refer to figure 1 In this embodiment, a sewage treatment device 100 for batch water inflow and continuous outflow, which includes water inflow regulation buffer zone I, anaerobic regulation reaction zone II, anoxic regulation reaction zone III and aerobic membrane reaction zone arranged sequentially along the water flow direction District IV. A sewage lifting pump 4 is arranged in the anoxic regulating reaction zone III, and the sewage lifting pump 4 communicates with the influent regulating buffer zone I and the aerobic membrane reaction zone IV through the first pipeline 13 respectively. The aerobic membrane reaction zone IV is provided with a sludge return pump 6 , and the sludge return pump 6 communicates with the inflow adjustment buffer zone I and the anoxic adjustment reaction zone III through the second pipeline 14 .

[0026] The water inflow adjustment buffer zone I is connected with the bottom of the anaerobic adjustment reaction zone II through the fi...
