Description

A kind of low energy consumption MBR integrated sewage treating apparatus

Technical field

This utility model belongs to sewage-treatment plant, particularly relates to a kind of low energy consumption MBR integrated sewage treating apparatus。

Background technology

Current China also has the masses of about 300,000,000 not have the water of cleaning to drink, and the drinking water of their daily life only has the surface water such as river, Lake Water, well water, in west area, even has quite a few people can only drink rainwater, snow water。It main reasons is that the pollution of water resource; current sewage discharge has been the primary pollution source of water resource; the process of sewage is the most important thing of water saving and protection of the water environment at present and in the future; separated from contaminants contained in sewage out or can be translated into harmless object by various methods by sewage disposal, so that sewage is purified。

Ozone has higher oxidability than liquid chlorine, bleaching powder, chlorine dioxide, it is possible to than chlorine, the speed of fast more than 600 times kills all antibacterials, the virus etc. that include chlorine and can not thoroughly kill；Some heavy metal ion such as oxidation precipitation such as cadmium, chromium, manganese, lead, hydrargyrum can be reached the purpose separated。But existing ozonization technology is not well developed in trade effluent field。Existing part of contaminated water treatment plant of China also begins to use ozone to process sewage, it is simply that placing several ozone distributors having fumarole bottom square or circular cesspool, not only ozone utilization rate is very low, and bactericidal effect is bad。

Additionally, existing decentralized type sewage process equipment, have only with single aerobic treatment technique, denitrogenation dephosphorizing is undesirable；The single aeration mode of some employings, energy consumption is higher；The plant treatment methods such as some employing artificial swamps, take up an area too big, and climate affects, fluctuation of service；Some device integrations are not high, poor processing effect。

Utility model content

The purpose of this utility model is in that to provide a kind of low energy consumption MBR integrated sewage treating apparatus, it is intended to solve the deficiencies in the prior art。

This utility model is achieved in that a kind of low energy consumption MBR integrated sewage treating apparatus, and this equipment includes water collect tank and process tank；

Described process tank is divided into upper strata tank body and lower floor's tank body, and described upper strata tank body is divided into water distributing area, floral region, drain district on current flow direction；Lay cobblestone bottom described floral region, described cobblestone is laid soil, planting plants in soil；It is provided with inverted siphon in described drain district；

Described lower floor tank body is divided into biological tank and MBR pond on current flow direction, and wherein, the water inlet of described inverted siphon is positioned at drain district, and described inverted siphon outlet is positioned at bottom biological tank；The water inlet that overflow outlet is MBR pond of described biological tank, is provided with biologic packing material between overflow outlet and the inverted siphon outlet of described biological tank；It is provided with MBR film in described MBR pond, is provided with aeration tube and return duct at the bottom of described MBR pond, in the access set water pot of described return duct water side；Described MBR film by pipeline with process tank outside suction pump be connected；

Being provided with suction pump in described water collect tank, described suction pump connects pipeline and is delivered in water distributing area by waste water in header tank。

Preferably, described cobble diameter is 1～5cm。

Preferably, between described water distributing area and floral region, between floral region and drain district, it is provided with barrier partitions respectively, described baffle bottom and be provided with through hole lower than cobblestone At The Height。

Compared to the shortcoming and defect of prior art, this utility model has the advantages that

(1) this utility model compact equipment, volume is little, floor space is little, and floor space therefore can be greatly decreased, and saves construction investment；

(2) this utility model organic pollutant removal rate is high, and stable effluent quality except making organic pollution be degraded, also has certain denitrogenation dephosphorizing function, is beneficial to retaining and breeding of nitrobacteria, and system nitrification efficiency is high；

(3) this utility model carries out solid-liquid separation efficiently, and its separating effect is much better than traditional sedimentation tank, and effluent quality is good, goes out aqueous suspension and turbidity close to zero, can direct reuse, it is achieved that sewage recycling。

Accompanying drawing explanation
