Description

生活污水处理装置Domestic sewage treatment plant

技术领域technical field

本实用新型涉及污水处理设备,具体地,涉及生活污水处理装置。The utility model relates to sewage treatment equipment, in particular to a domestic sewage treatment device.

背景技术Background technique

食堂污水的主要污染物为COD、动植物油、表面活性剂(如洗涤剂)、少量的NH3-N和TP。The main pollutants of canteen sewage are COD, animal and vegetable oils, surfactants (such as detergents), a small amount of NH3-N and TP.

目前,食堂生活污水处理甚少,主要是直接排入下水道进入污水处理厂,或者直接接暗管排出,通入地表水体,如流入湖泊、河流或小溪等。即使处理,也是进行简单的隔油处理,如利用油水分离器,进行简单的水、油和固体等分离,然后排放。At present, domestic sewage from canteens is seldom treated. It is mainly discharged directly into the sewer into the sewage treatment plant, or directly connected to the hidden pipe to discharge into surface water bodies, such as lakes, rivers or streams. Even if it is treated, it is a simple oil separation treatment, such as using an oil-water separator to perform simple separation of water, oil and solids, and then discharge.

在现有的专利文献中公开了生活污水的处理装置和方法。如:申请公布号为CN87102257的餐厅污水处理方法中一种处理高浓度有机物污水的新工艺技术,它革新生物接触氧化法,用5-10厘米粒度的煤渣填装在塔式装置内,分四层,每层间距5厘米,以好气菌、红螺菌挂膜,在气水比8-10∶1曝气量下,使污水与空气混合,经过煤渣与生物膜,停留时间在1小时内,可使COD4500毫克/升以下BOD2 000毫克/升以下的污水。又如:申请公布号:CN105712591A的发明公开了一种生活污水处理总站,它包括从左往右顺次设置的格栅渠、酸化调节池、初滤池、厌氧生物滤池、充氧池、好氧生物滤池、终滤池、植物检测池以及放流渠,厌氧生物滤池中的滤料内填装有厌氧生物载体,好氧生物滤池中的滤料内填装有好氧生物载体;每根长管上且沿长管的长度方向顺次设置有多个小孔,放流渠的侧壁上还设置有达标水排放口,所述的格栅渠与酸化调节池连通;充氧池内还固定安装有充氧泵和立柱。本发明的有益效果是:利用微生物吸附降解有机物、出水品质高、能够准确的检测出水的水质情况。Devices and methods for treating domestic sewage are disclosed in existing patent documents. For example: a new process technology for treating high-concentration organic sewage in the restaurant sewage treatment method with the application publication number CN87102257, which innovates the biological contact oxidation method, and fills the tower device with coal slag with a particle size of 5-10 cm, and divides it into four parts. Layers, with a distance of 5 cm between each layer, with aerobic bacteria and Rhodospirillum hanging on the film, under the air-water ratio of 8-10:1 aeration, the sewage is mixed with air, and the residence time is within 1 hour after passing through the cinder and biofilm. , can make the sewage below COD4500 mg/L and BOD2000 mg/L. Another example: Application Publication No.: CN105712591A The invention discloses a domestic sewage treatment terminal, which includes grille canals, acidification adjustment tanks, primary filter tanks, anaerobic biological filter tanks, and oxygenation tanks arranged in sequence from left to right , aerobic biological filter, final filter, plant detection tank and discharge channel, the filter material in the anaerobic biological filter is filled with anaerobic biological carrier, and the filter material in the aerobic biological filter is filled with good Oxygen biological carrier; each long pipe is provided with a plurality of small holes sequentially along the length direction of the long pipe, and the side wall of the release channel is also provided with a standard water discharge port, and the grid channel is connected with the acidification adjustment pool ; An oxygenation pump and a column are also fixedly installed in the oxygenation pool. The beneficial effect of the present invention is: the use of microorganisms to adsorb and degrade organic matters, the quality of effluent water is high, and the water quality of water can be accurately detected.

其中,如餐厅污水处理方法,仅提出了生物处理理论,但对装置或反应器系统涉及较少,甚至未充分考虑处理装置的制备,方法单一,无法去除大部分污染物等。一种生活污水处理总站,程序繁多,过程复杂,成本巨大,基本与城市污水处理厂相似,不适宜在中小规模污水产生量上应用。Among them, such as the restaurant sewage treatment method, only the theory of biological treatment is proposed, but little is involved in the device or reactor system, and the preparation of the treatment device is not even fully considered. The method is single and cannot remove most pollutants. A general domestic sewage treatment station has numerous procedures, complicated processes, and huge costs. It is basically similar to urban sewage treatment plants and is not suitable for application in small and medium-scale sewage production.

因此,急需要提供一种生活污水处理装置,该装置结构简单、成本很低,用于处理污水的材料便宜且易得,完全达标排放,无需再进入城市污水厂管道,直接排入河道,无任何风险。Therefore, there is an urgent need to provide a domestic sewage treatment device. The device has a simple structure and low cost. The materials used to treat sewage are cheap and easy to obtain. any risk.
