Problems solved by technology
However, in the application, there are problems in the conventional anaerobic treatment of medium and low concentration wastewater: 1. The low reaction gas production makes the return flow of the downcomer low, which requires a large external return flow and high energy consumption; 2. The organic load is low and it is not easy to form granular sludge. , and flocculent sludge is easy to lose and other problems

Embodiment
[0039] The core technology of the Cyclone Anaerobic Reactor (Cyclone Anaerobic Reactor referred to as CAR) of the present invention is the multi-phase multi-level flow field design control technology, through the design and regulation of the energy transfer mode and intensity between sludge particles, air bubbles and water, The characteristics of the flow field in the reactor can be effectively controlled, and a multi-phase, multi-level flow field with different characteristics can be constructed in the reactor, thereby ensuring the anaerobic reaction efficiency and the air-cement separation effect.
[0040] Through the specially designed three-dimensional swirling water distribution system, energy dissipation three-phase separator, and co-directional streamlined return water collection device, the energy dissipation effect on water flow, granular sludge and gas production can be combined (it can also be combined with a real-time flow field control system) , the CAR reactor of ...

The invention discloses a rotational flow anaerobic reactor for a waste water treatment system. The rotational flow anaerobic reactor for the waste water treatment system comprises a reactor chamber body as well as a gas and liquid separator and a water sealing tank which are arranged above the reactor chamber body and are connected with each other; a three-dimensional rotational flow water distributing system, a first-stage three-phase separator, a backflow water collecting system, a second-grade three-phase separator and a water outlet device are arranged in the reactor chamber body from bottom to top; a gas collecting system is arranged in the reactor chamber body; the gas collecting system is connected with a gas inlet of the gas and liquid separator; a separating liquid outlet of thegas and liquid separator is connected with a separating liquid backflow pipe in the reactor chamber body; and the three-dimensional rotational flow water distributing system comprises a water inlet and water distributing device and a water returning and water distributing device which is arranged above the water inlet and water distributing device. The three-dimensional rotational flow water distributing system with special design, an energy dissipation three-phase separator and a homonymous streamline type backflow water collecting device establish a multi-phase and multi-layer flow field with different characteristics in the reactor, so that anaerobic reaction efficacy and gas and cement separation effect are guaranteed.
Description
technical field [0001] The invention relates to a waste water treatment technology, in particular to a cyclone anaerobic reactor used in a waste water treatment system. Background technique [0002] Since the 1970s, wastewater anaerobic biological treatment technology has developed rapidly, and reactors represented by UASB, EGSB, and IC have been widely used, which have high load and low investment. It has the advantages of low operating cost and partial energy recovery. However, in the application, there are problems in the conventional anaerobic treatment of medium and low concentration wastewater: 1. The low reaction gas production makes the return flow of the downcomer low, which requires a large external return flow and high energy consumption; 2. The organic load is low and it is not easy to form granular sludge. , and the flocculent sludge is easy to lose and other problems. A good anaerobic reactor must have good sludge retention capacity; have the conditions for f...
