Embodiment 1

[0021] Such as figure 1 A kind of multi-stage settlement garden sewage regeneration system shown, comprises diversion ditch 1, air blower 6, sedimentation treatment tank 27, inflatable splint 7, first clapboard 8, second clapboard 9 and self-priming pump 10, inflatable splint, The first partition and the second partition are fixed in the sedimentation treatment tank and divide the inner space of the sedimentation treatment tank into a slow flow settlement zone 2, a filter zone 3, a buffer zone 4 and a flocculation settlement zone 5, and the water diversion ditch is located on the upper part of the slow flow settlement zone And connected with it, the bottom of the slow flow settlement area is provided with an upwardly inclined slow flow slope 11 near the side of the inflatable splint, the slope of the slow flow slope is 45°, the inflatable splint is fitted with the slow flow slope, and the inflatable splint is provided with a cavity. An inflatable tube 12 is provided in the cav...

Embodiment 2

[0023] The difference between this example and Example 1 is that the flocculant is made by the following method: by 1% FeCl 3 , 1% Al 2 (SO 4 ) 3 , 0.8% pullulan, 2% bentonite, and the balance is the mass percentage of water. After weighing each component, FeCl 3 with Al 2 (SO4 ) 3 Add water, stir continuously for 3 hours, then age for 2 days, then add bentonite and stir for 1 hour at a speed of 1000 r / min, and finally add pullulan and stir for 1 hour at a speed of 200 r / min, and the rest are exactly the same as in Example 1.

Embodiment 3

[0025] The difference between this example and Example 1 is that the flocculant is made by the following method: by 0.7% FeCl 3 , 0.6% Al 2 (SO 4 ) 3 , 0.7% pullulan, 1.8% bentonite, and the balance is the mass percentage of water. After weighing each component, FeCl 3 with Al 2 (SO 4 ) 3 Add in water, stir continuously for 2.5h, then age for 1.5d, then add bentonite and stir at a high speed of 800r / min for 1.5h, finally add pullulan and stir at a speed of 120r / min for 1.2h, and the rest are the same as those in the examples 1 is exactly the same.

[0026] The operating principle of the present invention is: the sewage is collected into the slow-flow settlement area through the diversion ditch, and heavy impurities such as stones in the sewage in the slow-flow settlement area will sink at the bottom under the blocking of the slow-flow slope and the action of its own gravity. The sewage overflows to the filter area through the grid holes on the inflatable splint. When th...

Abstract

The invention discloses a multistage settling and garden sewage regenerating system which comprises a flume, a blower, a precipitation treatment tank, an aeration clamping plate, a first partition board, a second partition board and a self-sucking pump, wherein the interior space of the precipitation treatment tank is divided into a subcritical flow settling region, a filtering region, a buffer region and a flocculating setting region by the aeration clamping plate, the first partition board and the second partition board, a subcritical flow slope inclining upwards is arranged at the bottom of the subcritical flow settling region, a cavity is formed inside the aeration clamping plate, an inflating pipe is arranged inside the cavity, the inflating pipe penetrates through the top of the aeration clamping plate to be connected with the blower, gate holes are formed in the two sides of the upper part of the aeration clamping plate, a composite filtering structure is arranged inside the filtering region, a flowing hole is formed in the first partition board, an overflow pipe is formed in the second partition board, the overflow pipe is positioned at the lower part of the flocculating setting region, a blow-off pipe and a water outlet pipe are arranged inside the flocculating setting region, and the water outlet pipe is connected with the self-sucking pump and connected in parallel to a flocculating agent conveying system. The multistage settling and garden sewage regenerating system provided by the invention can achieve continuous processing of garden sewage, the equipment investment is less, the running cost is low, the treatment efficiency is high, and the treatment effect is good.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multi-stage settlement garden sewage regeneration system. Background technique [0002] Ecological garden refers to the garden green space system built under the guidance of ecological principles. In this system, ecological tribes composed of trees, shrubs, herbs, vines, etc. are coordinated among the populations, and there are compound levels and suitable seasons. Color, plants with different ecological characteristics can have their own place, make full use of sunlight, air, land, nutrients, water, etc., to form a harmonious, orderly and stable community, it is the highest level of urban landscaping work, and it is the material and spiritual quality of human beings. The inevitable result of the development of civilization. [0003] In the design process of ecological gardens, sewage treatment is an important project. Fountains, landscape pools, irrigation and other...
