Integral purification device and method for particles in rain and sewage

Abstract

The invention relates to an integral purification device and an integral purification method for particles in rain and sewage. The device consists of three parts including a rotational flow riffling unit, a diameter change precipitation unit and an up-flow filter unit in vertical overlapped arrangement, wherein the rotational flow riffling unit comprises a rotational flow riffling tube, a water inlet pipe, a sand discharge pipe, a siphon cover, a siphon pipe, a water sealing groove, a water discharge pipe, a first perforation plate, a second perforation plate and a third perforation plate, the diameter change precipitation unit comprises a diameter change precipitation pool, the up-flow filter unit comprises a filter chamber case, a filter chamber base plate, a filter pool, filter materials and a filter water outlet. The device and the method provided by the invention have the characteristics that the particle removal efficiency is high, the blockage is avoided, the energy is saved, the efficiency is high, the water load impact capability is high, the occupied area is small, the investment and operation management cost are low, and the like. The method and the device can be widely applied to the particle purification in water discharge pipelines with greater slope and the rainfall runoff of roofs, elevated roads and the like.

Description

Technical field [0001] The invention involves the field of rainwater and sewage treatment technology, especially a purification device and method of rainwater and sewage. Background technique [0002] With the rapid development of urbanization, non -point source pollution caused by rainwater runoff has gradually become an important source of urban water pollutants.The pollutants in the urban rainwater runoff are mainly derived from the wet sinking caused by precipitation and pouring air pollutants and the soluble scrubbing of the urban impervious surface pollutants, while the latter accounts for more than 90%of the total amount of rainwater runoff pollutants.Granularity is the main carrier of urban non -permeable surface pollutants, such as: atmospheric settlement, car tail gas, tire wear, snow melting agent, sediments on construction sites, solid garbage, and osmotic fluid containing large amounts of pollutants (COD, nutritional substances such as COD, nutritional substances, Or...
