Embodiment 1

[0018] The waste water flows into the bioreactor container 3 through the waste water inlet pipe 1, and the volume of the reactor container is 1 ton. The yeast 14 irradiated by the ultrasonic head 11 flows into the bioreactor container 3 through the water outlet 2, mixes with the newly entered waste water, and flows forward along the partition 8 with a water flow rate of 40 t / day. The yeast 14 flowing to the waste water drain pipe 6 is intercepted by the filter bag 7, and most of them will be pumped into the ultrasonic radiation chamber 12 by the peristaltic pump 10 through the water inlet 5 of the peristaltic pump, and the pumping speed is 64 L / min. The volume of the ultrasonic radiation chamber 12 is 1L, the radiation time is 5min, and the frequency of the ultrasonic head 11 is 1M. The intelligent pulse unit 13 is set to turn on the peristaltic pump 10 at 0.0157min, and turn on the ultrasonic head 11 at 5min, which is a unit cycle control. The yeast 14 irradiated by ultrasou...

Abstract

The invention provides an ultrasound and microbe cooperated wastewater treatment device which comprises a reactor container. A partition plate is arranged in the reactor container and divides the reactor container into a first cavity and a second cavity. A wastewater inlet pipe is arranged at the upper end of the first cavity, and a valve is arranged on a pipe body of the wastewater inlet pipe. A heating bar and a temperature control sensor are arranged in the second cavity, a wastewater discharging pipe and a peristaltic pump water inlet are arranged on the lower side of the second cavity, and the inner pipe orifice of the wastewater inlet pipe is sleeved with a filter bag. The peristaltic pump water inlet is connected with a peristaltic pump, an ultrasound irradiation chamber and a water outlet in sequence through pipes, and the water outlet is formed in the upper end of the first cavity. An intelligent pulse control unit is arranged above the ultrasound irradiation chamber, a plurality of ultrasound heads arranged in an array mode are arranged under the ultrasound irradiation chamber, and the intelligent pulse control unit is connected with the ultrasound heads. A plurality of aerator pipes are arranged at the bottom inside the reactor container. The intelligent pulse unit is added in the device, so that the working time and frequency are intelligently controlled, the device cyclically treats wastewater, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a device for ultrasonically cooperating with microorganisms to treat wastewater. Background technique [0002] There are many methods of sewage treatment at present. The biological method has developed rapidly and has become one of the main methods of sewage treatment due to its advantages of low investment, high efficiency, low operating cost, stable operation, good effluent quality, and good sedimentation performance of sludge. The biological effects of ultrasound are well exploited in numerous industries. Under ultrasonic working conditions without destroying the enzyme protein structure, ultrasonic irradiation can promote the interaction between substrate molecules, strengthen the process of reactants entering and products leaving the enzyme active center, thereby increasing enzyme activity and promoting enzyme-catalyzed reactions. Steady-state cavitation produced by ...
