Abstract

The utility model belongs to the field of sewage treatment and discloses a domestic sewage treatment device. The device comprises a solid-liquid separator, a sedimentation tank, a first filter tank, a microorganism reaction tank and a second filter tank which are connected sequentially through pipelines, wherein the solid-liquid separator treats domestic sewage to remove large particle impurities in the domestic sewage; packing at the bottom of the sedimentation tank is river sand; packing at the bottom of the first filter tank is divided into two layers, namely, a zeolite powder layer and an activated carbon layer, sequentially from bottom to top; a valve is arranged on a pipeline between the sedimentation tank and the first filter tank; a pH value detector is arranged between the first filter tank and the microorganismreaction tank; a feeding port is formed in the upper end of the microorganism reaction tank; and packing at the bottom of the second filter tank is a cationic polyacrylamide layer, a clean water outlet pipeline is also arranged, and a plate-and-frame filter is also arranged on the pipeline.

Description

A kind of device of processing sanitary sewage

Technical field

The utility model belongs to environmental protection equipment technical field, relates to a kind of device of processing sanitary sewage.

Background technology

Sanitary wastewater is the sewage producing in human lives's process, is one of primary pollution source of water body.Mainly ight soil and wash water.The sanitary sewage amount that discharge everyone every day in city is 150-400L, and its amount has substantial connection with standard of living.In sanitary sewage, contain large amount of organic, as Mierocrystalline cellulose, starch, carbohydrate and fat protein etc.; Also often contain pathogenic bacteria, virus and parasitic ovum; Muriate, vitriol, phosphoric acid salt, supercarbonate and the sodium of inorganic salts, potassium, calcium, magnesium etc.Total feature is nitrogenous, sulfur-bearing and phosphorous height, and post-processed is more difficult.People should water conservation. and China's actual conditions are more special, and water resources occupancy volume per person is few, spatial distribution imbalance.Along with Chinese Urbanization's, industrialized acceleration, the demand gap of water resources also increases day by day.Under such background, sewage treatment industry becomes new industry, at present and tap water production, water supply, draining, middle water reuse industry in status of equal importance.

In field of Environment Protection, how sanitary wastewater is purified, and reach emission standard and recycling is the technical issues that need to address.

Utility model content

The purpose of this utility model is to make up the deficiencies in the prior art, and a kind of energy-saving and purifying urban domestic wastewater device is provided.The utility model completes by following technical solution:

Process a device for sanitary wastewater, comprise the solid-liquid separator that pipeline connects successively, settling tank, the first filtering basin, microbial reaction pond and the second filtering basin;

Described solid-liquid separator is processed sanitary sewage, removes large granule foreign in sanitary sewage;

The bottom filling of described settling tank is the river sand of 50cm thickness, and the particle diameter of river sand is 2mm;

The bottom filling of described the first filtering basin is divided into two-layer, is zeolite bisque and active carbon layer from down to up successively, and every layer thickness is 30cm;

On pipeline between described settling tank and the first filtering basin, be provided with valve, for regulating flow velocity;

Between described the first filtering basin and microbial reaction pond, be provided with pH value detector, for detection of the potential of hydrogen of current that enters microbial reaction pond;

The top in described microbial reaction pond is provided with dog-house, for dropping into acid-base modifier, also can be used as ventilating pit simultaneously;

The bottom filling of described the second filtering basin is cationic polyacrylamide layer, and thickness is 50cm, and centre is provided with pure water inlet pipeline, is provided with plate filter on pipeline, for collecting microorganism and tunning is prepared bacterial manure.

Have above-mentioned knownly to description of the present utility model, the utility model possesses following advantage:

Adopt physico-chemical process and microbial process to combine, effectively removed various impurity and the chemical substance in sanitary wastewater; For the pollutent of different sizes and kind, adopt multiple precipitation medium and filtration medium to carry out multiple Adsorption; The microorganism of collecting can be used to prepare bacterial manure, has avoided microorganism to be discharged in water body simultaneously, avoids causing secondary pollution of water.

Brief description of the drawings

Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.

Diagram is the structural representation of a kind of device of processing sanitary wastewater of the present invention.

In Fig. 1: 1 solid-liquid separator, 2 settling tanks, 3 first filtering basin, 4 microbial reaction ponds, 5 second filtering basin, 6 plate filters, 7 valves, 8pH value detector, 9 dog-houses.

Embodiment

Described solid-liquid separator is processed sanitary sewage, removes large granule foreign in sanitary sewage, comprises stone etc.

The bottom filling of described settling tank is the river sand of 50cm thickness, and the particle diameter of river sand is 2mm; Can be for some granule foreigns, such as colloid throw outs etc., adsorb and precipitate;

The bottom filling of described the first filtering basin is divided into two-layer, is zeolite bisque and active carbon layer from down to up successively, and every layer thickness is 30cm; Adopt two-layer absorption setting, its can effectively carry out different-grain diameter and kind organic compound absorption and remove;

On pipeline between described settling tank and the first filtering basin, be provided with valve, for regulating flow velocity, avoid, because current are excessive, pollute thing and adsorbing halfway defect;

The top in described microbial reaction pond is provided with dog-house, for dropping into acid-base modifier, also can be used as ventilating pit simultaneously; By dropping into acid-base modifier, make the solution in reaction tank reach the best pH that is applicable to microorganism fermentation, keep good reaction efficiency;

The bottom filling of described the second filtering basin is cationic polyacrylamide layer, and thickness is 50cm, is used for the negative charge compounds such as adsorpting pigment;

Described the second filtering basin are also provided with pure water inlet pipeline, are provided with plate filter on pipeline, for collecting microorganism and tunning is prepared bacterial manure; Maximally utilise microorganism raw material, and avoided microorganism to bring water body into, caused secondary pollution.

Microorganism in described microbial reaction pond is the bacterial classification of conventional compound (for example phenyl amines, the Phosphorus compound of nitrogen) in can degradation of sewage, for example rhodococcus, thiobacillus, genus bacillus, pseudomonas aeruginosa, nitrococcus and Paracoccus denitrificans etc., or their combination.

Although the utility model here specifically describes in conjunction with the specific embodiments, but be understandable that this is illustration instead of restriction, do not departing under the prerequisite of the spirit of the present invention that accessory claim limits, in the scope of disclosed and accompanying drawing above, it is all possible reasonably changing and revising.
