Embodiment Construction

[0015] As shown in the figure, the device of the present invention includes a filter tank 1, a filter element 2, an ultrasonic generator A12a, and an ultrasonic generator B12b are arranged in the filter tank, and the sewage to be treated enters the tank body from the raw water inlet 3 on the filter tank , the clean water filtered by the filter element is sent out from the clean water outlet 4, and the sludge that does not pass through the filter element is discharged from the sludge outlet 5; the pipeline between the raw water inlet 3 and the water source to be treated is sequentially installed with a first solenoid valve 7 and a water pump 6. The pipeline leading out of the clean water outlet 4 has three branches, all the way through the second solenoid valve 8 to the clean water pool, all the way through the third solenoid valve 9 to discharge, and all the way through the fourth solenoid valve 10 to the water outlet of the water pump 6 ; The sludge outlet 5 passes through the...

Abstract

The invention relates to the field of energy conservation and environmental protection and provides an ultrasonic-pulse self-cleaning wastewater reusing device and a method, the whole filtration and the washing processes are automatically controlled through a PLC control system, thereby greatly improving the degree of automation of the treatment processes; and a back-wash way combining the pulse way and the ultrasonic cleaning is adopted, thereby changing the traditional cleaning way of adding a chemical cleaning agent and having the constant-flow backwash, avoiding the possible secondary pollution, greatly improving the backwash effect and also cleaning oily dirt adhered to a filter core. The wastewater reusing device and the method have the advantages of reasonable structure, good treatment effect, convenient cleaning and maintenance of the filter core and convenient realization of automatic control.

Description

technical field [0001] The invention belongs to water treatment technology, and relates to a sewage recycling device and method capable of treating river water, domestic sewage and other water bodies to higher water quality above reclaimed water. Background technique [0002] China is a country with severe drought and water shortage. The total amount of fresh water resources is 2.8 trillion cubic meters, accounting for 6% of global water resources, ranking fourth in the world after Brazil, Russia and Canada, but the per capita is only 2,200 cubic meters, which is only 1 / 4 of the world average. 1 / 5 of the United States, ranked 121st in the world, is one of the 13 countries with the poorest per capita water resources in the world. Therefore, under the premise of advocating water conservation, it is an urgent problem to be paid attention to to develop reclaimed water preparation devices suitable for various water bodies and improve water utilization efficiency. [0003] Exist...
