Problems solved by technology

However, for the scattered sewage sources, if the centralized treatment is still used to purify these sewage, more transportation costs will be incurred; Purification system or method, the initial equipment cost is also high; especially when it comes to the treatment of rural sewage, for example, rural sewage is different from dense and concentrated cities, which are generally scattered, and some places are even sparsely populated and concentrated Sewage treatment is obviously not in line with the actual situation, and the transportation cost in the early stage is high, so rural sewage often needs to be treated on site, but it is even more unrealistic to install sewage treatment equipment and equip corresponding technical operators in every place that needs to be treated. Equipment investment costs are higher

Embodiment Construction

[0028] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.

[0029] See figure 1 with figure 2 as shown, figure 1 is a schematic diagram of a sewage purification system according to an embodiment of the present invention; figure 2 yes figure 1 top view. use figure 1 with figure 2 The sewage purification system 1 of the embodiment shown includes a regulating pond 101, a filtering pond 102, an aeration pond 103 and a wetland purification pond 104 connected in sequence; the regulating pond 101 collects sewage, and controls the speed at which the sewage flows out to [1.5, 2 ] ton / day; the filter pool 102 filters the insoluble impurities and suspended solids in the sewage, and the suspended solids content in the sewage treated by the filter pool 102 is within the range of [40, 50] mg / L; oxygenation The poo...

Abstract

The invention relates to a sewage purification system and method. The sewage purification system comprises an adjusting tank, a filter tank, an aeration tank and a wetland purification tank which arecommunicated sequentially, wherein the adjusting tank collects sewage and controls the flow velocity of sewage in the range of [1.5, 2] ton per day; the filter tank filters insoluble impurities and suspended solids in sewage, and the content of suspended solids in the sewage treated by the filter tank is in the range of [40,50] mg / L; the aeration tank is used for increasing the content of dissolved oxygen in the sewage to the range of [2,3] mg / L; the wetland purification tank is used for purifying sewage through filtration by plant root systems and soil, and the content of the suspended solidsin the purified water is in the range of [5,10] mg / L, the content of total phosphorus is in the range of [0.5,1] mg / L, and the content of total nitrogen is in the range of [10,15] mg / L. according tothe sewage purification system and method, sewage can still be purified at a lower cost and better purified water is obtained.

Description

technical field [0001] The content disclosed in the present invention relates to a sewage purification system and method. Background technique [0002] Sewage purification is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. The purified water treated by the sewage purification system can be used in many fields, such as industrial water, agricultural irrigation, aquaculture, medical water, etc. [0003] At present, sewage purification technology is commonly used in a large amount of sewage that needs to be treated centrally, because sewage treatment itself requires a lot of cost, high initial investment cost, and large area. Therefore, sewage purification usually adopts centralized treatment to reduce the risk of high initial investment costs. However, for the scattered sewage sources, if the centralized treatment is still used to purify these sewage, more transportation costs will be incurred; Purificati...
