Abstract

The utility model of a water purifier for parks, in a lake sewage treatment equipment in city park 1, is used for the treatment of lake sewage, which is a collection of sewage from the first rain and arid rivers. In city parks, a rectangular, dividing channel with two transverse ways for forming pure water is arranged in the purified lake water which is purified by the connection structure formed by park sewage 2, cyclic lake water 3 and cyclic water from biological pipe well 4 and oxidation pipe 5, thereby connecting the oxidation pipe to one way of the diving channel, wherein the other way of the diving channel is connected with double oxidation purified water in cyclic lake 10 The oxidized sewage 7 from the diving channel, which forms residue sludge 8 after being divided and deposited, then becomes purified discharged water 9 transformed from park sewage and purified lake water in the cyclic lake.

Description

The park purifier

(1) technical field

The utility model relates to a kind of lake water purifying plant of Urban Parks, and especially park lake water utilizes the park purifier of park sewage disposal.

(2) background technology

The existing lake water of Urban Parks, mainly from rainwater and artificial recharge, because the lake, city is positioned at low river basin, the first rain sewage and the dry flow sewage of periphery all easily pollute lake water, so that long-term stagnant water is black smelly, the ecoscape of grievous injury urban environment and park lake water.

Existing lake water protection is to be formed by connecting with the discharging waters by wastewater interception pipe, sewage pumping station, processing factory site.When dry flow sewage was cleaned, lake water separated sewage; But when the rainy day, the rainwater flow is much larger than the dry flow sewage amount, and a large amount of overflow sewage pipelines of storm sewer, and in this case, the dirty shunting of rain was lost efficacy, periphery just rain sewage and dry flow sewage compile the lake, and precipitating sludge worsens and pollutes lake water.

In lake pollution was administered, a kind of sewage disposal of biological pipe well (ZL 93248145.0) was to implement the necessary circulation of park sewage disposal lake reoxygenation to purify and gas water lift power apparatus.

(3) utility model content

The purpose of this utility model provides a kind of park purifier, can be the non-irrigated flowing water source of lake, park self-cleaning with the park sewage disposal, and with the five-day BOD for the lake reoxygenation changes the water one-period, reach the radical cure lake water pollution the water purification purpose.

The purpose of this utility model is achieved in that in the Urban Parks, is connected with oxidation pipeline recirculated water by park sewage, circulation lake water, biological pipe well, and ecological shunt conduit is set, and the oxidation pipeline is connected with shunt conduit one side water; The other side of shunt conduit is then purified waste water with circulation lake reoxygenation and is connected.Because the quantity of circulating water high power of biological pipe well oxidation is in circulation lake water amount, the oxidation sewage of circulation shunting only be decontamination cycle lake water, need not returned sluge, thus greatly simplify the oxidation shunt conduit, and be the vegetable fertilizer of lake view to precipitate excess sludge.When being suitable for returned sluge biochemistry at park sewage, its shunt conduit then in the channel bottom, is set up precipitation bucket and reflux line, in the biochemical pipeline of collecting precipitation mud backflow park sewage.

Owing to adopt such scheme, self-cleaning lake water in the lake, park, and need not wastewater interception pipe and existing second pond, in biological pipe well, only adopt general pipeline open caisson, simple in structure.

(5) embodiment

In Fig. 1:

The park sewage 2 of Urban Parks 1, be recycled lake water 3 dilutions, the biological pipe well 4 of input cyclic oxidation, biological pipe well shunting oxidation pipeline 5, the oxidation sewage 7 of input shunt conduit 6 is shunted the precipitation excess sludge 8 purification lake water for the purification draining 9 of park sewage and circulation lake 10.

In Fig. 2:

Park sewage 2 is recycled the biological pipe well 4 of lake water 3 dilution inputs, be one or more pairs of gardens shape or the square or perpendicular stream of rectangle pipeline, oxidation of circulating sewage aeration and gas water lift power apparatus thereof, and through oxidation pipeline 5, shunt conduit 6, the precipitation water purification of shunting oxidation sewage 7.

In Fig. 3:

Shunt conduit 6 is a kind of elongated rectangular shape, two limit transverse structure water purifying flat flow precipitation canals, on one side continuous crossing current oxidation sewage 7, precipitation excess sludge 8; The other side then flows over continuously and concentrates the purification lake water that purifies draining 9 and circulation lake 10.

In Fig. 4:

In the horizontal bottom of water purification shunt conduit 6, be suitable for returned sluge 11, set up precipitation bucket 12 and reflux line 13, in the biochemical pipeline 15 of collecting precipitation mud 14 backflow park sewage 2.
