Problems solved by technology

Although these methods can also play a certain role in alleviating the pollution of rivers, these effects are often temporary and cannot fundamentally solve the problem of black and smelly sewage in urban rivers and ditches. Pollution will worsen the ecological environment of urban rivers and ditches

Embodiment Construction

[0020] In Fig. 1, one end of the overflow water distribution plate 1 is connected and fixed with the top of the overflow dam 2, and the other end is suspended above the water worm packing layer 18, and many small holes are punched on the water distribution plate. The overflow dam 2 is formed by pouring concrete, and its height is 0.5-1.8m higher than the normal water level of the ditch in the non-flood season. The barrier 3 is installed on the crest of the overflow dam 2 . The submersible pump 4 is installed upstream of the overflow dam 2, and its water outlet is connected together with the fountain nozzle 6 through a pipeline. The fountain earthworm biological reaction pool 5 is arranged on the bank of the ditch, and the fountain nozzle 6 is arranged in the pool. The water wheel biological turntable 7 is arranged in the outlet channel of the earthworm bioreactor. The emergent plant area 8 is arranged on both banks of the ditch, and its water inlet is connected with the wate...

Abstract

The invention discloses an ecological purifying device of urban effluent, which comprises the following parts: biological earthworm reactor, biological rack, hydraulic aerating distributor, biological water-wheel type rotary disc, ecological purifying functional area and aeration filter purifying system, wherein the hydraulic aerating distributor connects biological earthworm reactor through overflow distributing board, which interconnects emergent aquatic plant area of ecological purifying functional area; the biological water-wheel type rotary disc is set in the outlet channel of biological earthworm reactor.

Description

technical field [0001] The invention belongs to the field of urban sewage ecological treatment, in particular to an in-situ ecological purification treatment device for urban ditch sewage. Background technique [0002] With the continuous improvement of the level of urbanization in our country, the number of cities and population are increasing. In the past 10 years, the discharge of urban sewage in my country has also increased at a rate of 5% per year, while the current centralized treatment rate of urban sewage in my country is only about 15%, and more than 80% of urban sewage in the country is directly treated without any effective collection and treatment. Discharged into nearby water bodies, the rivers and canals that used to discharge floods and beautify the landscape have become natural sewage ditches, especially in my country's 2,200 county towns and 19,200 towns, where the sewage discharge accounts for more than half of the country's total sewage discharge , but the...
