[0100] Experimental example, concrete operation and effect verification of the present invention

[0101] Production and construction of high-efficiency biodegradation filter reactor:

[0102] Self-made Φ0.2m×4.5m high-efficiency biodegradable filter reactor, the reactor is mainly composed of reactor column 1, water distribution area 2, supporting layer 3, sand filter layer 4, melon seed flake layer 5, suspended packing layer 6, The perforated aeration pipe 7 and the water distribution pipe 8, in addition, the reactor also includes an inlet and outlet water system 9, a backwashing system 10 and a carbon source supply system 11.

[0103] The shell of column 1 is made of plexiglass with a thickness of about 5mm, and the bottom plate of the reactor is connected with a DN20 PVC backwash water inlet pipe and a DN5 air inlet hose. A filter plate with a diameter of 200mm is installed at a distance of 20cm from the bottom of the column, and two layers of pebbles with a diameter of 4-...

Abstract

A biodegradation filter reactor, which comprises: a reactor cylinder (1). The reactor cylinder (1) is provided therein in a downward sequence with a biological reaction region and a deep filtration region. A separation layer consisting of a sheet-shaped material is provided at the junction between the biological reaction region and the deep filtration region. A lightweight suspended filter of which the particle size is 4-8 mm is provided in the biological reaction region. A filler of a great specific gravity of which the particle size is 1.0-2.0 mm is provided in the deep filtration region. The specific gravity of the deep filtration region filler is 2.5-3 times of the specific gravity of the biological reaction region. Also disclosed is a method employing the filtration reactor for treating polluted water.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a high-efficiency biodegradation filter reactor and a method for using it to treat black and odorous water. Background technique [0002] With the acceleration of urbanization and the improvement of industrialization, the total amount of wastewater discharge in my country has been increasing year by year in recent years. The direct discharge, sneak discharge, and leakage of wastewater have caused river water to be polluted in various forms, and many water bodies have Seasonal or year-round black and smelly, black and smelly water not only brings unpleasant feelings to people in terms of color and taste, especially its pollutants will eventually cycle through the food chain and affect people's life and health. The black and odor of urban rivers is mainly the result of the imbalance of oxygen supply and consumption of water caused by excessive pollution. Under a...
