Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1 to Figure 2 As shown, the polluted water body purification treatment device of the present embodiment includes a housing 1, and the housing 1 is divided into N aerobic pools 2, N-1 anaerobic pools 3, two filter pools 4 and two inlet pools. / drainage pool 5, the aerobic pool 2 and the anaerobic pool 3 are alternately arranged next to each other, the two filter pools 4 are respectively adjacent to the aerobic pool 2 at both ends, and the two inlet / drainage pools 5 are respectively It is arranged at both ends of the housing and adjacent to the corresponding filter pool 4. The two inlet / drainage pools 5 are respectively provided with a drainage pump 52, a drain pipe 51 and a drainage bottom that can discharge the water in the drainage pool 5 to the outside. Pipe 53, the bottom of the inlet / drain pool 5 is provided with a wat...

Abstract

The invention discloses a contaminated water purification treatment device which comprises a housing, wherein the housing is partitioned into N aerobic tanks, N-1 anaerobic pools, two filtering basinsand two water inlet / outlet tanks, wherein the aerobic tanks and the anaerobic pools are adjacently arranged in sequence; the two filtering basins are respectively adjacent to the aerobic tanks at twoends; the two water inlet / outlet tanks are respectively arranged at two ends of the housing and are adjacent to the corresponding filtering basins; the two water inlet / outlet tanks are respectively provided with a drainage pump, a drainage pipe and a drainage bottom pipe; a water inlet control valve and a water inlet distribution pipe are arranged at the bottom of the water inlet / outlet tanks; aerating apparatuses are arranged at the bottoms of the aerobic tanks; the upper parts of the aerobic tanks are communicated with the anaerobic pools; a plurality of water inlets are formed in the bottoms of the anaerobic pools or on side faces close to the bottom; N is a natural number not less than 2. The contaminated water purification treatment device disclosed by the invention has the advantages that anaerobic-aerobic (A / O), UNITANK, multipoint water inflow and biological aerated filter treatment processes are organically combined, high-efficiency nitrogen and phosphorus removal of the contaminated water is realized, and the treatment device is low in manufacturing and operating cost and high in treatment efficiency.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a device for purifying and treating polluted water. Background technique [0002] Surface water purification technologies generally include engineering measures such as dredging, sewage interception, revetment, and aeration, as well as ecological restoration measures such as artificial aquatic plants, artificial floating islands, aquatic plants, and water aquaculture. The outstanding feature of my country's surface water pollution is eutrophication, high concentrations of nitrogen, phosphorus and other nutrient pollutants, showing the characteristics of low carbon-to-nitrogen ratio and low carbon-phosphorus ratio, resulting in insufficient carbon sources for nitrogen removal. Although the commonly used aeration method can increase the concentration of dissolved oxygen in water and oxidize ammonia nitrogen into nitrate nitrogen, the removal effect on total nitrogen is not ...
