Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings.

[0019] The membrane bioreactor is divided into anaerobic zone, anoxic zone and aerobic zone according to the volume ratio of 1:1:4, and ≥2 partition baffles are set in the aerobic zone (depending on the volume of the reactor), and the membrane module Placed at the end of the aerobic zone, the UCT reflux process is adopted during operation, that is, the sewage flows back from the aerobic zone to the anoxic zone, and the anoxic zone returns the mixed solution to the anaerobic zone, and the ORP probe is used to monitor the anaerobic zone and the anoxic zone The oxidation-reduction potential was monitored by DO probes to monitor the dissolved oxygen in the aerobic zone. The overall water flow in the reactor is in a broken-line flow mode, and the water is pumped through the membrane module to the water storage tank by the suction pump.

Abstract

This invention relates to a wastewater treatment apparatus, especially UCT-broken line flow membrane bioreactor for reclaimed water reuse. The apparatus comprises: a float valve, a punched aeration tank, a liquid flow meter, a gas flow meter, a vacuum pressure gauge, a hollow fiber membrane module, a diving reflux pump, a single-stage self-priming pump, an electronic stirrer, an aeration pump, an ORP potential tester, am oxygen dissolution tester, a water storage tank, and an adjusting pool. The membrane bioreactor is divided into an anaerobic zone, an anoxic zone and an aerobic zone at a volume ratio of 1:1:4. Two partition boards are set in the aerobic zone. The ORP probe can monitor the redox potential of the anaerobic zone and the anoxic zone, and broken line flow mode of water flow in oxygen dissolution reactor in the aerobic zone. A dump pump is used to pump water into the water storage tank via the membrane module.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a UCT-broken line flow membrane bioreactor directly used for reuse of reclaimed water. Background technique [0002] With the development of human society, the problem of water resources has been paid more and more attention by people. Fresh water resources are non-renewable and also one of the indispensable natural resources for human survival and development. According to the survey, the available water resources on the earth account for 0.6% of the total water on the earth, and the distribution of resources in the world is extremely uneven. According to the data provided by the United Nations Habitat Center, the number of people facing water shortages has accounted for 20% of the total number of people in the world, that is, about 1.2 billion people. my country is a country that lacks water resources, and there are water shortages in many areas. However, a large amount of urban s...
