under longitudinal wall A8 in clarifier-tank, A8 both ends Cross section is affixed with disjunctor at a quarter in the middle part of the siding of cross wall plate A1 and A7 both ends respectively, the clarifier-tank opening cylinder at this time Inner cavity has been divided into separate tank A4, secondary settling tank conjoined vat A5 and one heavy pond conjoined vat A2, biochemical filler room A10 and secondary settling tank The several small individual cylinders of A11 and pond；Separate tank A4 is accounted in top, 2/5ths height of occupancy clarifier-tank cylinder body, biochemical filler room A10 With 1/5th height of clarifier-tank cylinder body, a heavy pond A11 occupies 2/5ths height of clarifier-tank cylinder body, and separate tank web plate A12 is Separate tank A4 bottom plates, the separate tank A4 are the separate tanks for filtering aquiculture net cage bottom sediment, and the separate tank A4 is set More than two layers 2000 height of eye filter density nets are equipped with, bottom separate tank web plate A12 sets 30mm sieve screen apertures,（Two layers of biochemical filler Room A10 is from this sieve screen apertures filler）, the net cage body bottoms pass through suction pump water supply hose 9 and mating suction pump 5 The separation of separate tank A4 level-ones is pumped into, is cleared up by the fraction collection that highly dense net is detached,（It is shown in Figure 3）After separation Water body flows into two floor biochemical filler room A10, the biochemical filler room A10 using sulphur, lime stone or pyrite, dolomite to fill out Material, for particle diameter between 3.5-6mm, laying depth is 60-80mm, reactor filler bed net plate A13 sieve screen apertures setting 3mm Rectangle mesh, it is ensured that filler particles are not lower to be leaked, and it is conjoined vat that pond A11 and A2 sinks in the filler chamber A10 lower floors one, the disjunctor Cylinder A2 is transparent open cylinder body, the minimum 150mm of width, a heavy pond glar easy to clean；Secondary settling tank conjoined vat A5 and A2 Equally transparent open cylinder body, length are clarifier-tank total lengths, and the minimum 150mm of width is open, have in clarifier-tank longitudinal wall A8 and The outer longitudinal wall A9 of clarifier-tank and A1, A7 surround the open cylinder of composition, sedimentation in secondary sedimentation tank mud easy to clean；Secondary settling tank overflows water out A14 Supernatant water out is arranged in the middle part of secondary settling tank conjoined vat A5 outer walls A9, is highly arranged under reactor filler bed net plate A13 opposite It answers at 20mm；One heavy pond L-shaped baffle pipe overflows water out A15 and is highly arranged on two layers of filler chamber A10 upper ends with respect to 4/5ths It puts；One heavy pond L-shaped baffle pipe connection water inlet A 16 is arranged on casing wall A8 with respect to heavy 2/5ths position of pond A11 upper ends, L-shaped Baffle pipe occupies in secondary settling tank, when extension valve B is closed（It is shown in Figure 1）, a heavy pond L-shaped Baffle pipe overflows water out A15 and begins with when overflowing flow such as secondary settling tank by L-shaped baffle pipe, and filler chamber A10 water has covered at this time Sulphur, lime stone or pyrite, dolomite are filler, and filler is all impregnated in water, and the water surface divides in filler chamber A10 upper ends five Everywhere, when the secondary settling tank overflows water out A14 and there are flowing out soon, 5 setting time of self-priming suction pump is to have stopped extracting net Case bottoms（It is shown in Figure 3）, all filter such as filler chamber of lower floor A10 carries out autotrophic denitrification to separate tank A4 sewage Intensive treatment strengthens absorption denitrogenation, minimum 3 hours of dephosphorization processing time, after the water process strengthens absorption 3 hours, flexible valve Door opens level-one switch, and a heavy pond clear water enters baffling mouth B11 and B4 in overlap condition by outer tube runner and flows into two Heavy pond secondary precipitation, at this time a heavy pond and secondary settling tank be in connected state, extension valve runner exit is closed, and water is not It can be flowed into outside pond from valve（It is shown in Figure 1）, it is heavy that the heavy pond precipitation water by valve B runners baffling flows at a slow speed two Pond, at this time secondary settling tank supernatant water flowed out outside clarifier-tank by unrestrained mouth of a river A14 or caged-culture waters, when the anhydrous outflows of unrestrained mouth of a river A14, When checking that a heavy pond clear water is in shape, extension valve B secondary switch is opened, valve plate B9 rests on outer tube runner at this time In the middle part of baffling mouth B4, inner sleeve runner baffling mouth B12 and B14 is Chong Die with outer tube runner baffling mouth B4 simultaneously, this state is stretched Valve is in two level unlatching, and a heavy water enters baffling mouth B11 by outer tube runner and enters secondary settling tank at this time, at this time secondary settling tank Clear water can be entered simultaneously by baffling mouth B4 outside the baffling mouth B14 inflow inner sleeve runner discharges pond in overlap condition or net Case water body（It is shown in Figure 1）, the extension valve B outer tube runners water inlet B 2, water outlet B 6 respectively disjunctor be fixed in it is vertical Wall A8 and longitudinal wall A9 lower ends, for extension valve B outer sleeve bottoms from clarifier-tank cylinder bottom A18, minimum is that 30-50mm ensures muddy water not The height that can be flowed out, during the anhydrous outflow of the extension valve B runners, one, secondary settling tank clear water it is substantially drained, close valve, it is remaining Band muddy water has connection small suction pump promotion to be back to point by the heavy pond sludge reflux mouth A19 of secondary settling tank sludge reflux mouth A17 and one From pond A4 filtration treatments again.

Aforementioned specific implementation process is water purification treatment system structure and application, aforementioned while be an aquiculture net cage Body cultured product excreta, residual bait, caged-culture waters denitrogenation, dephosphorization water process purification process；Clarifier-tank A be stereo biological filter tank from Denitrification intensive treatment reactor is supported, is chronically exposed under daylight and exposes to the sun and rain, preferably selects and relies the hard price of high temperature quality low Honest and clean high-quality PC materials, except extension valve B inner sleeves and spacer pin be can be with split in addition to, other clarifier-tank A components descriptions connect Affixed body can be the whole disjunctor of cast, and clarifier-tank A is a water process cleaning system that can independently use with other fields.
