Abstract

The utility model provides a life sewage treating apparatus, the basic structure of the utility model comprises an oxidation pond which is provided with a water inlet and a water outlet, filler, an aeration device and a sewage draining hole, wherein, the aeration device and the sewage draining hole are arranged on the bottom of the oxidation pond. The main body portion of the oxidation pond is divide into three layers by an upper sieve plate and a lower sieve plate, a filler layer is arranged between the upper sieve plate and the lower sieve plate, the upper part of the upper sieve plate is provided with a stable water layer and a water outlet which are used for the soiless culture of plants, and the lower part of the lower sieve plate is provided with a water inlet, the aeration device and a sludge settling bucket for treating and recycling domestic sewage on site.

Description

A kind of sewage treatment unit

The utility model relates to a kind of sanitary sewage on-the-spot disposal reclamation set, particularly a kind of bio-contact oxidation technology and plant purification technology of integrating, be used for that garden crops such as greenery patches, gardens, garden flowers and trees are irrigated or the sanitary sewage on-the-spot disposal reclamation set of aqiuculrue, belong to water saving and environmental technology field.

Existing sanitary sewage on-the-spot disposal reclamation set is except that buried, all are arranged on ground, no matter its device with which kind of material is built, all be difficult to and surrounding enviroment, particularly the landscape environments such as gardens of the garden of Urban House biotope, office or school, hotel or the institutes of recuperating are coordinated mutually, their existence makes people in vision and the psychological unplessantness displeasure that produces easily; Utilize the shallow water pools such as culturing the floating plant Herba Eichhorniae that sewage is purified, have advantages such as the easy construction of construction, stable and reliable operation, saving energy consumption and working cost are cheap, but its floor space is all bigger, in densely populated Urban House biotope, it almost is impossible building large-area like this Sewage treatment systems in office or school, hotel or the rest home.

The purpose of this utility model provides a kind of compact construction, floor space is little, can combine with afforestation, coordinates mutually with surrounding enviroment, and backwater is used for that garden crops such as greenery patches, gardens, garden flowers and trees are irrigated or the sewage treatment unit of aqiuculrue.

The utility model is achieved in that its basic structure of this sewage treatment unit comprises that the oxidation pond, filler, the oxidation pond bottom that are provided with entery and delivery port are provided with quick-fried device of air and sewage draining exit, the main part of oxidation pond is separated into three layers by upper and lower sieve plate, it between the upper and lower sieve plate packing layer, upper sieve plate top is provided for the stable water layer and the water outlet of plant soil-less culturing, and following sieve plate below is provided with water-in, aerating apparatus and sludge settling bucket.

The packing layer of described sewage treatment unit is to hang to be arranged on up and down the many groups fiber bundle-like filler between the sieve plate or rubble, cinder.

The quick-fried device of air of described sewage treatment unit is to be arranged on down the aerate head of sieve plate bottom and the air pump that is attached thereto.

Rock cotton board or the plastic foam that also is provided for plant soil-less culturing in the water layer stablized on the upper sieve plate top of described sewage treatment unit, and the water outlet of stablizing the water layer side is provided with filter screen.

The utility model is owing to be provided with the plant purification layer on the basis of biological contact oxidation pond, so obviously strengthened the effect of sewage disposal, the water body of its discharging can meet irrigation of garden crops such as greenery patches, gardens, garden flowers and trees and the water quality requirement of aqiuculrue fully.Again because the utility model integrates waste disposal plant and plant growing, greening installation, so compact construction not only, floor space is little, and waste disposal plant is merged mutually with the landscape environment in biotope, garden gardens, has strengthened and has beautified effect.

Describe main contents of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is among the structural representation figure of sewage treatment unit: 1, oxidation pond body 2, purification water layer 3, water outlet 4, water outlet filter screen 5, upper sieve plate 6, filler 7, aeration head 8, water-in 9, sludge settling bucket 10, mud discharging mouth, 11, following sieve plate

What Fig. 1 provided is a kind of round shape biopurification oxidation pond, and oxidation pond body 1 top is main part, and section is rounded, rectangle or square, and its top is uncovered fully; Body bottom, pond is a sludge settling bucket 9, tapered or the bottom of a pan shape; The main part of pond body is separated into three layers by upper and lower sieve plate, is packing layer between the upper and lower sieve plate, and two sieve plates are supports of filler 6; Upper sieve plate 5 is the stable water layer that includes matrix such as the rock cotton board that is used for plant soil-less culturing or plastic foam with top, plant relies on matrix to support and absorbs nutritive substances such as consuming the moisture of stablizing water layer and nitrogen, phosphorus, potassium by root system and grows, so this stable water layer also claims the plant purification water layer.For floatability waterplant such as Herba Eichhorniaes, also can not establish matrix and directly place to stablize on the water layer and grow.The filter screen 4 that purifies 3 settings of water layer side water outlet can prevent that the floatability waterplant from dashing from the pond body with current; Following sieve plate 11 belows are water inlet and aeration layer, and water-in 8 is arranged at the top of sludge settling bucket 9, and mud discharging mouth 10 is positioned at the vertex of a cone place of below of sludge settling bucket.Planting vegetables such as Chinese celery, water spinach on purification water layer 2, its root system gathers elongation in steady water layer.

The sewage treatment unit of the present utility model use of can also contacting is the soft plastic fibrous bundle as the filler of first step biopurification oxidation pond, purifies the matrix of placing foamed polystyrene foam plastics in the water layer, wherein plants Chinese celery; The filler of second stage biopurification oxidation pond is that granularity is the rubble and the cinder of 5-6 millimeter, and rubble is layered on lower floor, and thickness is 1.5 meters, and cinder is layered on the upper strata, and thickness is 1 meter, purifies and directly cultures Herba Eichhorniae on the water layer; But this sewage treatment unit batch production production, partly be embedded in during use underground so that the management of body top, pond cultivated plant and viewing and admiring.The purifying waste water of water outlet enters the irrigation that water reservoir promptly can be used for garden and gardens flowers and plants, trees, also can directly enter the pond and be used to breed fish.
