Water conservancy sewage tretament system

Abstract

The invention discloses a water conservancy sewage tretament system. The system comprises a raw water pond, an alga pond, a carbon dioxide tank and a discharge pond, wherein the raw water pond is connected with the alga pond through a peristaltic pump, the alga pond is connected with the discharge pond through a pipeline, the carbon dioxide tank connected through a pipeline is arranged on one sideof the alga pond, carbon dioxide in the carbon dioxide tank is introduced into the bottom of the alga pond, the discharge pond is connected with the raw water pond through a reflux pump, and the bottoms of the raw water pond and the alga pond are connected to a mud pit through pipelines. The system is simple in structure and reasonable in design; organic matter and nitrogen and phosphorus in rawwater are decomposed by algae in the alga pond, carbon dioxide is supplemented to produce oxygen to achieve a purpose of greenhouse gas emission reduction, and the system is suitable for promotion anduse.

Description

technical field

[0001] The invention relates to the field of sewage treatment, in particular to a water conservancy sewage treatment system. Background technique

[0002] With the rapid development of society, the problem of environmental pollution is becoming more and more serious. As a source of pollution, domestic sewage is often treated by physical methods, chemical methods, and physical and chemical methods. These methods not only waste resources, but also At the same time, there may be secondary pollution, and the biological method is not easy to separate the algae when the sewage comes out. Therefore, how to easily separate algae while treating domestic sewage, and at the same time improve the treatment of domestic sewage by algae has always been a difficult problem faced by the whole society. Contents of the invention

[0003] The object of the present invention is to provide a water conservancy sewage treatment system to solve the above technical problems. [00...

Examples

Embodiment Construction

[0016] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as Figure 1-2 As shown, a water conservancy sewage treatment system includes a raw water pool 1, an algae pool 4, a carbon dioxide tank 5, and an outflow pool 6. The raw water pool 1 is connected to the algae pool 4 through a peristaltic pump 9, and a filter screen 2 is installed in the raw water pool , the algae pool is provided with a layer of chlorella pyrenoidosa 10, a layer of Scenedesmus obliquus 11, a layer of Synechococcus elongatus in sequence from left to right, and a layer of chlorella pyrenoidosa 10, a layer of Scenedesmus obliquus 11, a layer of slender algae The Synechococcus longum layer 12 is a fluidized bed design, and all kinds of algae on the Chlorella pyrenoidosa layer, Scenedesmus oblique layer, and Synechococcus elongatum layer are all attached to and grown on the filler, and the algae pool 4 flows The fille...
