Embodiment 1

[0016] A kind of process of the present invention handles the eutrophication water source of waterworks, take the waterworks that daily output is 12,000 cubic water as an example, concrete process steps are as follows:

[0017] Step 1) The water from the eutrophication water source is provided with a grid made of stainless steel or PC material from the bottom of the biofilm filtration pretreatment tank with a volume of 4 × 20 × 10 cubic meters and an hourly flow rate of 500-600 tons. The water inlet enters the water for pretreatment by biofilm filtration;

[0018] Step 2) enter the first filter tank, put into the first filter tank with a specific gravity of 0.189, a single volume of 20 * 28mm spiral staggered filter material made of ABS, the upper part of the first filter tank Both the water outlet and the backwash outlet are provided with grilles made of PC material. The bottom of the first filter tank is equipped with air pipes with a spacing of 1m, and small holes with a di...

Abstract

The invention discloses a process for treating a eutrophic water source in a water plant. The process comprises the following specific steps of: feeding water from the eutrophic water source into a biological film filtering pond for pretreating; and feeding into a first sewage treating pond and a second sewage treating pond which are provided with different spiral overlapped filtering materials with different specific weights for deeply filtering. In the process for treating the eutrophic water source from the water plant, novel spiral overlapped filtering materials are adopted in a filtering step, so that the flow structure is simplified; and the process has the advantages of high water saving property, saving in space, saving in energy, easiness for managing, and the like.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a process for treating eutrophic water source of a waterworks. Background technique [0002] In the prior art, the influent water of the waterworks generally adopts three main process steps of biological pretreatment, fluidized bed biologically activated carbon filter, and sand filter to achieve the purpose of purifying water, but in fact, with the water quality The deterioration of the water quality, these three processes alone can no longer meet the water quality treatment requirements. Moreover, these three processes require a large area, complex structure, large power consumption, and high management intensity. [0003] Therefore, it is a problem to be solved in this technical field to invent a kind of treatment process of tap water with small footprint and high treatment efficiency. Contents of the invention [0004] In order to overcome the deficiencies in th...
