Problems solved by technology

The main problems of these two methods are: (1) large investment (1500-3000 yuan per ton. day. sewage), high operating cost (08-3.0 yuan per ton. sewage)
This kind of huge investment has made some cities, especially some small and medium-sized towns or enterprises and institutions unable to afford it.
(2) Most of the on-site construction is based on civil engineering, which cannot achieve serialization, installation, and factoryization
Make it difficult for the environmental protection industry to form an industrial scale and benefits
(3) Most of them only solve the emission standards, and do not realize renewable resources
(4) Suspended substances and kicked substances in sewage are treated together with water-soluble substances, which is difficult to treat and has poor treatment effect

Embodiment Construction

[0007] The present invention will be further described below in conjunction with the accompanying drawings, the sewage is sent into the reaction tower 2 by the pump 1 after the additives, and the physicochemical reaction of the mechanism such as complex coagulation is carried out in the reaction tower, and the suspended pollutants and the colloidal state pollution are removed. thing. The sediment from the reflection tower enters the water purifying agent regenerator 3, and the regenerated water purifying agent is returned to the sewage inlet. The sewage out of the reflection tower drives the hydro-generator 4 and then enters the biological contact oxidation tank 5. In the biological contact oxidation tank, the water-soluble pollution in the sewage is biochemically treated and effectively removed. Then introduce the multi-layer filter tank 6. The blower 7 of the biological contact oxidation tank adopts the power output by the hydro-generator of the reaction tower as the power s...

Abstract

The invention provides a high-efficiency energy-saving sewage treatment method. Sewage added with a purifying agent is sent to a reaction tower through a pump; sediment out of the reaction tower enters a purifying agent regenerator; the regenerated purifying agent flows back to a sewage feeding port; the sewage out of the reaction tower drives a water wheel generator, enters a bio-contact oxidation tank, and then is led into a multi-layer filter; an air blower of the bio-contact oxidation tank adopts power output by the water wheel generator of the reaction tower as a power source; and water out of the multi-layer filter is purified recycle water. The method has the advantages of less construction investment, low running cost, good purification effect, big industrial ratio of equipment andthe like.

Description

Technical field: [0001] The present invention relates to a method for treating sewage, in particular to a method for treating sewage. Background technique: [0002] There are mainly two kinds of existing sewage treatment methods, one is physical chemical method, the other is biochemical method. The main problems of these two methods are: (1) large investment (1500-3000 yuan per ton. day. sewage), high operating cost (08-3.0 yuan per ton. sewage). This huge investment has made some cities, especially some small and medium-sized towns or enterprises and institutions unable to afford it. (2) On-site construction, which is mainly based on civil construction, cannot be serialized, installed, and factory-like. It is difficult for the environmental protection industry to form an industrial scale and benefit. (3) Most of them only meet the emission standards, and do not realize renewable resources. (4) The suspended matter, kicking matter and water-soluble matter in the sewage a...
