Novel wastewater purification device

Abstract

The invention discloses a novel wastewater purification device. The device comprises a filter box, a water tank and a return system, wherein a filter material filling space is formed in the filter boxand used for purifying wastewater; the water tank is arranged at the bottom of the filter box and used for containing water purified by the filter box; the return system is arranged on one side of the filter box and used for returning water leaked during purification by the filter box to the filter box for secondary purification; a prism frustum casing is connected to the top end of the filter box, and an inverted prism frustum water inlet is connected to the top end of the prism frustum casing; the return system comprises a sewage return pipe, a return pump and a return water tank, one end of the sewage return pipe is communicated with the return water tank, and the other end extends into the inverted prism frustum water inlet through the return pump; front open channels communicated with an inner cavity of the return water tank are formed in the outer wall of the water tank and used for receiving water leaked during purification by the filter box and guiding the water into the return water tank. The device can effectively purify sewage and is simple in structure, convenient to operate, energy-saving, environmentally friendly and wide in application range.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a novel wastewater purification device. Background technique [0002] At present, with the development of science and technology, industries and other fields are progressing rapidly, and people's living standards are also rising, followed by a sharp increase in the amount of industrial wastewater and household wastewater. Industrial wastewater often contains solid impurities and some harmful substances, which brings great difficulties to the later purification of sewage. Traditional water purification uses sedimentation and other methods. This method of purifying sewage is not only time-consuming, but also consumes resources and delays The time of the enterprise has also greatly increased the production cost of the enterprise. [0003] In addition, due to the shortage of domestic fresh water resources and the increase in the amount of urban domestic sewage year by y...

Problems solved by technology

Industrial wastewater often contains solid impurities and some harmful substances, which brings great difficulties to the later purification of sewage. Traditional water purification uses sedimentation and other methods. This method of purifying sewage is not only time-consuming, but also consumes resources and delays The time of the enterprise also greatly increased the production cost of the enterprise

[0003] In addition, due to the shortage of domestic fresh water resources and the increase in the amount of urban domestic sewage year by year, the existing tap water purifiers cannot be used for domestic sewage treatment and cannot meet the current environmental protection requirements
