Embodiment Construction

[0017] Such as Figure 1-2 As shown, the rainwater flows into the rainwater filter device through the rainwater collection well cover 7, and flows through the stainless steel mesh grid 2, the filter material 1, and the textile cloth 3 in sequence, and finally the outlet water flows into rivers or lakes and other water bodies from the rainwater pipe. During this flow-through process, large particles and floating objects are trapped on the stainless steel mesh grid 2, and the pollutants that are not trapped further flow into the filter material unit with the rainwater, and the filter material 1 is placed on the fine stainless steel mesh In the grid 2, the filter material 1 filters and absorbs the rainwater, and the tiny particles, soluble metals, and organic matter are intercepted by the filter material 1. Subsequently, the rainwater flows through the textile cloth 3, and the textile cloth 3 surrounds the periphery and the bottom of the filter unit to prevent the loss of the fil...

Abstract

The invention provides a suspended type catch basin filtering device. The suspended type catch basin filtering device has the filtering function, is suspended in a manhole cover outside the hole mouth of the catch basin, and is used for filtering sediment and pollutant in rainwater so as to prevent the sediment and pollutants from entering the rainwater pipe network and reduce pollution of the collected rainwater. The filtering device comprises a support frame, a hook, a reticulated grid, textile, a filter material and an overflow pipe. According to the filtering device, rainwater is filtered by using the gravity of rainwater and the filter material unit in the device. Besides, the suspended type device is flexibly mounted in the catch basin, and is convenient in disassembly and trash removal.

Description

technical field [0001] The invention relates to a suspended rainwater well filtering device. technical background [0002] With the rapid development of urbanization and economy, the contradiction of insufficient water resources and urban ecological problems have become more and more prominent in many areas of our country. At present, the urban water pollution control in our country has not paid enough attention to the pollution of rainwater runoff, and there are no corresponding regulations and technologies. specification. The runoff generated by rainwater directly flows into the downstream rivers and lakes, which undoubtedly becomes one of the main input sources of pollutants in water bodies. The restoration of water bodies such as rivers and lakes is mainly aimed at the treatment of rivers and lakes themselves, without considering the control of pollutants brought by rainwater runoff. [0003] At present, countries such as Europe and the United States have had many year...
