Description

Catering sewage treatment system

Technical Field

The utility model relates to a food and beverage sewage treatment field particularly, relates to a food and beverage sewage treatment system.

Background

Along with the improvement of living standard of people and the change of catering structure, the production amount of catering waste water is rapidly increased. Because the kitchen waste and the restaurant waste water are solid-liquid mixtures, the liquid kitchen waste and the solid kitchen waste are separated firstly, and then the solid and the liquid waste water are treated respectively.

Kitchen waste water, commonly known as swill, is a domestic waste formed in the process of domestic consumption of residents, is extremely easy to rot and deteriorate, emits stink, and spreads bacteria and viruses. The organic fertilizer is mainly characterized by rich organic matter content, high water content and easy decay, the properties and smell of the organic fertilizer can cause bad influence on environmental sanitation, and harmful substances such as Bulloch microorganisms and mycotoxin are easy to grow.

What harm kitchen waste water has:

1. the kitchen waste water has obvious harm and resource duality and is characterized in that:

(1) the water content is high and can reach 85 to 95 percent;

(2) high salt content, hot pepper, acetic acid, etc.;

(3) high organic matter content, protein, fiber bundle, starch, fat, etc.;

(4) rich in nitrogen, phosphorus, potassium, calcium and various trace elements;

(5) pathogenic bacteria, pathogenic microorganisms, and the like exist.

2. Because the kitchen waste wastewater contains higher organic matters, the kitchen waste wastewater is easily affected by microorganisms, the putrefaction phenomenon occurs, the putrefaction phenomenon is more serious when the kitchen waste wastewater is placed for a longer time, and the generated percolating water and foul gas breed mosquitoes and cause adverse effects on the environment.

3. The meat protein and animal fat substances in the kitchen waste wastewater are mainly from livestock and poultry providing meat food, and after the livestock directly eat the kitchen waste which is not effectively treated, homologous pollution of cannibalism easily occurs, cross infection of epidemic diseases between people and livestock is caused, the human health is harmed, and the spread of certain fatal diseases can be promoted.

4. Leachate generated during stacking of kitchen waste and restaurant wastewater enters a sewage treatment system, and the content of organic matters is increased, so that the burden of a sewage treatment plant is increased, and the operation cost is increased.

In the preferred embodiment of the present invention, the ultraviolet generator is an ultraviolet lamp 1506.

Specifically, in the present embodiment, the ultraviolet generator is an ultraviolet lamp tube, and more specifically, an electromagnetic induction rectangular ultraviolet lamp 1506.

The electromagnetic induction UVC lamp is based on a Faraday electromagnetic induction principle, adopts a structure similar to a transformer to complete the coupling of electromagnetic power of a primary winding (a coupling coil) and a secondary coil formed by a plasma loop, and generates efficient energy transfer. The UVC lamp tube with long service life and low light attenuation is formed. The penning gas composed of Hg at low pressure and quantitative Ar, Kr and other atoms in the quartz tube forms stable plasma discharge under the excitation of high-frequency electromagnetic field. When Hg atoms in a metastable state in the plasma return to a steady state, valence electrons belonging to the Hg atoms can release energy in the form of rays. Wherein 253.7nm and 185.0nm are ultraviolet rays in UVC wave band.

Electromagnetic induction UVC ultraviolet ray etc. have following advantage:

1. the filament has no electronic powder pollution, and the service life of the lamp tube is long for sixty thousand hours and is easy to operate.

The light attenuation is small. About 10% per ten thousand hours. The effective life of the lamp tube is about 6-8 times that of the conventional UVC lamp tube.

3. The lamp tube is elaborately developed for five years, can be directly lighted under water by adopting a special design, does not need a quartz protective sleeve (with the transmittance of 80 percent), and has higher ultraviolet efficiency.

4. The use, the installation and the maintenance are convenient. The initial efficiency of ultraviolet rays of the low-pressure mercury lamp is inversely proportional to the pipe diameter, namely the initial efficiency is higher as the pipe diameter is thinner, but the light attenuation is larger (the load of the inner pipe wall is larger), otherwise, the initial efficiency is low, and the light attenuation is small because the pipe diameter phi 47 of the electromagnetic induction UVC ultraviolet lamp is far larger than the wall load of the traditional lamp phi 15, so the light attenuation is small.

5. Due to the fact that the electromagnetic induction UVC ultraviolet lamp tube is high in power and concentrated in ultraviolet energy, 253.7nm can kill bacteria and viruses and microorganisms such as blue algae and green algae in water within short time, 185.0nm can photolyze COD in water, and water quality is purified.
