Embodiment Construction

[0031] The urban sewage treatment capacity is 240,000 tons per day, the hourly water volume is 10,000 tons, and the volume of a single pool is 10,000 cubic meters. There are 10 pools in total. The specifications of each pool are: 80 meters long, 25 meters wide, and 5 meters deep. Among them, the aerobic zone (1) is 20 meters long, the facultative zone is 30 meters long, and the anaerobic zone (3) is 30 meters long. There is no physical dividing plate in between, and it is completely determined by the fluid flow state, path, speed and other dynamic characteristics. Determined; each of the three areas is provided with biological growth carriers-fillers with different specific surface areas, aerobic zone filler (4): 500-1000 square meters / cubic meter; facultative oxygen zone filler (5): 1000-1500 square meters / cubic meter; Filler (6) in the anaerobic zone: 1500-3000 square meters / cubic meters. By immobilizing microorganisms with different growth characteristics and different quan...

Abstract

The invention refers to the anaerobic-compatible oxygen-aerobic integrated sewage treatment and the reusing equiopment. It realizes anaerobic, compatible oxygen and aerobic reaction regions in single equiopment, forms three kindso f bio-systems, finishes multiple kinds of bio-reaction course, and utilizes feed-gas power in aerobic region to realize the waterpower and mud circulation, thus at energy-conservation state realizes getting rid of organic matter, nitrogen, phosphor and so on; at the same time changes thep ast stable parameter control into variable paremter control, realizes the optimization of above processes and the auto-control system by the detecting-feedback system of on-line instrument, realizes intelligent sewage-treating process and can produce many kinds of reusing waters.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment and reuse. In particular, it involves a new type of sewage treatment technology and equipment that realizes the three biological growth states of anaerobic, facultative and aerobic, and has the functions of denitrification, dephosphorization and water reuse of sewage. Background technique [0002] As we all know, the shortage of water resources, energy shortage, and serious water pollution are the three major factors restricting the development of my country's national economy. The shortage of water resources leads to insufficient water runoff and groundwater sources, so that the total amount of pollutants that can be accommodated in the water system is small, and it is easy to cause water environment pollution; energy shortage prevents us from using high-efficiency but high-energy-consuming technologies to eliminate pollution , so that the ability to reduce the discharge of pollutants t...
