Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] like figure 1 and figure 2 Shown, the present invention comprises anaerobic acidification tank 3, aerobic degradation tank 4, settling tank 5, catalytic tank 6, membrane separation tank 7 and clean water tank that are buried in carbon steel below ground 1 successively along the flow direction of sewage 8. One side of the anaerobic acidification tank 3 communicates with the sewage pipe 2, and the other side communicates with the adjacent aerobic degradation tank 4 through the first overflow port 11, and the aerobic degradation tank 4 passes through the first overflow port 11. The second overflow port 12 communicates with the settling tank 5, the settling tank 5 communicates with the catalytic pool 6 through the third overflow port 13, and the catalytic pool 6 is separated from the membrane by the fourth overflow port 14 The pool 7 is i...

Abstract

The invention provides a hidden sewage treatment method and equipment. The hidden sewage treatment method comprises the following steps of: firstly, biochemical reaction: sealing and storing sewage for anaerobic decomposition, then introducing air for aerobic decomposition, finally precipitating, pumping lower sludge and enabling upper liquid to enter the next step; secondly, catalytic reaction: adding a catalyst in liquid obtained by reaction in the first step to enable pollutant in the sewage to be oxidatively degraded to generate innoxious substances; and thirdly, membrane treatment: filtering a reaction product in the second step through an ultrafiltration membrane, removing residual impurities from water and finally sterilizing to obtain purified water. The hidden sewage treatment method and equipment provided by the invention have the beneficial effects that due to the adoption of biochemical and efficient catalytic technology integrated government, hazardous and noxious substances with high concentration and high difficulty can be treated; and the equipment becomes compact by an underground hidden mode and integrated combination.

Description

technical field [0001] The invention relates to a sewage treatment method and treatment equipment, in particular to a concealed sewage treatment method and treatment equipment. Background technique [0002] my country is a country that lacks water resources and is also a country with very serious water pollution. Water pollution control is a very important problem. The current sewage treatment methods are relatively simple, and cannot treat some refractory, high-concentration, and high-pollution pollutants, and occupy a large amount of land resources. These sewage treatment equipment are generally exposed outdoors and are easily affected by the climate, which affects the treatment speed and effect. Contents of the invention [0003] The purpose of the present invention is to provide a simple, practical and reliable concealed sewage treatment method and treatment equipment. [0004] Technical scheme of the present invention is: [0005] A concealed sewage treatment metho...
