Problems solved by technology

[0005] In my country, there are no more than two ways to deal with polluted mud or water: 1. Landfill sludge, such as Shanghai Suzhou Creek sludge is landfilled in Nanhui Old Port; 2. Most cities use dehydration, sieving, and drying Or incineration, this method has high cost, high energy consumption and serious secondary pollution

[0044] see figure 1 , the biological dialysis system of this embodiment is suitable for purification pools that have been filled with sewage or sludge.

[0045] In this embodiment, two first water injection pipes 12 are inserted into the first purification tank 11 to the bottom of the pool, and the top of the first water injection pipe 12 is connected with a first water delivery pipeline 14 and connected to a water pump. The side wall is provided with several first drainage boards 13 and second drainage boards 16. The first drainage boards 13 extend toward the obliquely upward direction, that is, the direction of the sludge surface, and expose 50 cm of the sludge surface, and the second drainage boards 16 also obliquely upward. direction, that is, the direction of the sludge surface, and is completely submerged in the sludge to increase the effect of water circulation. A layer of reeds 15 is also planted on the surface of the sludge in the first purification tank 11 .

[0054] see figure 2 , the biological dialysis system of this embodiment is suitable for purification ponds of unfilled sewage or sludge.

[0055] In this embodiment, the water delivery unit extending into the second purification tank 21 includes five second water injection pipes 22 and a horizontal water delivery channel 23 laid on the bottom of the second purification tank 21 and communicating with the second water injection pipe 22. The water conveying channel 23 is made up of several horizontally arranged drainage plates; the horizontal water conveying channel 23 is provided with a first vertical drain plate 24 and a second vertical drain plate 25, and the first vertical drain plate 24 faces upwards, i.e. The direction of the sludge surface extends, and exposes 50cm of the sludge surface, and the second vertical drainage board 25 also extends upwards, that is, the direction of the sludge surface, and is completely immersed in the sludge to increase the effect of water circ...

Abstract

The invention discloses a biodialysis system which comprises a purification tank, wherein one or multiple water delivery units extend in the purification tank; each water delivery unit is provided with one or multiple water drainage devices which are communicated with the water delivery unit; each drainage device extends towards the top surface of the purification tank; and each water delivery unit is further connected with a water supply unit. According to the invention, pollutants in sewage or sludge can be subjected to physical / chemical / biological purification processes under the action of water, so that the water ecology can be restored, and the basic and important self-purification capacity and assimilative capacity of the water body can be restored and enhanced. Thus, the biodialysis system and the decontamination method have the advantages of energy saving, emission reduction, low carbon, sustainability and environment friendliness.

Description

technical field [0001] The invention relates to the technical field of water body sludge purification, in particular to a biological dialysis system and a cleaning method. Background technique [0002] With the economic development of the people in recent years, the expansion of the construction scale of many cities, the increase of population, the increase of overload of various garbage and discharges have seriously affected the quality of life and life safety of urban people, and are severely testing urban planning. , Wisdom and ability of decision makers. [0003] After polluting mud and water, it was discovered that the demolished pesticide factories, chemical fertilizer factories, pharmaceutical factories and other poisonous land problems; after years of remediation of the heavily polluted three lakes and three rivers with little effect, there were many news about the decline of water quality in the sea and estuaries. It has been reported one after another, and there...
