Problems solved by technology

[0002] At present, the waste liquid (a lot of oily compressor oil, heavy metals and other impurities mixed into emulsified waste liquid with different pH) is generally used in places where air compressors are generally used. The problem of environmental pollution caused by direct discharge without treatment, although some places have also adopted There are some processing methods, but most of them are digging pits underground to accumulate and then do simple collection processing
The above methods are difficult to really solve the problem, and occupy a certain land area, and will cause new pollution to the surrounding environment

Embodiment Construction

[0029] Now in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0030]As shown in Fig. 1, Fig. 2 and Fig. 3, the treatment method of the oily waste liquid of the present invention is realized in this way, the waste liquid is first passed through the decompression muffler 1 and the buffer shunt 2, and then through the small hole throttle plate 3 Make the waste liquid fall into the first separation chamber 4 in the form of droplets with very small kinetic energy. Under the action of buoyancy and specific gravity, the oil with light specific gravity rises slowly, and the water with heavy specific gravity descends slowly, and accumulates on the liquid surface of the first separation chamber 4 After the oil on the top increases, it will overflow to the oil storage bin 10, and the pre-separated water that sinks below the first separation bin 4 will be sent to the second separation bin 5 through the control of the valve. The ...

Abstract

A process for treating the sewage containing oil includes separating the oil from waste ldiquid by floatage and specific weight in the first separating cabin, separating oil from water by electric field generated by positive and negative electrode in the second separating cabin, and adding acid-alkali balancing agent and the additive able to capture oil ions and metal ions to the water. Its advantages are high effect, compact structure and no secondary pollution.

Description

Technical field: [0001] The invention relates to waste liquid treatment equipment. Background technique: [0002] At present, the waste liquid (a lot of oily compressor oil, heavy metals and other impurities mixed into emulsified waste liquid with different pH) is generally used in places where air compressors are generally used. The problem of environmental pollution caused by direct discharge without treatment, although some places have also adopted There are some processing methods, but most of them are digging pits underground to accumulate and then do simple collection. Above-mentioned method is difficult to really solve the problem, and has taken certain land area, also can cause the new pollution of its surrounding environment. Invention content: [0003] The purpose of the present invention is to provide a device that can separate the oil-containing waste liquid, and the separated water can reach the national discharge standard, and can collect the oil and other s...
