Mobile Pickling Waste Liquid Treatment System

Abstract

The invention discloses a movable acid pickling wastewater treatment system which comprises a movable box, and an aerated neutralization tank, an aeration device, an alkali liquor adding device, a flocculant adding device, a filter press, a clear liquid pool, a filtering device, a multi-parameter water quality testing meter and a control electrical cabinet which are arranged in the movable box, wherein the control electrical cabinet controls the operation of the aeration device, the alkali liquor adding device, the flocculant adding device, the filter press, the filtering device and the multi-parameter water quality testing meter. The movable acid pickling wastewater treatment system disclosed by the invention is strong in moving capability, and the movable box can be integrally arranged on a truck at a time by using a forklift or a hoisting machine and then are transported to needed places efficiently and fast, so that the serious risk of wastewater in the processes of transportation and storage can be lowered, and the wastewater treatment cost is reduced. Meanwhile, according to the movable acid pickling wastewater treatment system, the water quality of filtered liquid can be detected in real time by using the multi-parameter water quality testing meter, so that unqualified filtered liquid can be prevented from being discharged.

Description

technical field [0001] The invention relates to the technical field of waste liquid treatment, in particular to a mobile pickling waste liquid treatment system. Background technique [0002] In recent years, with the rapid development of China's industrial production system, pickling has penetrated into various fields such as petroleum, chemical industry, textile, food, medicine, transportation, electronics, nuclear energy, military industry, construction, and civil use. The problem of waste liquid treatment after pickling, because each pickling engineering service team is mobile construction in various places all the year round, each project produces hundreds of kilograms to hundreds of tons of pickling waste liquid, which is different from ordinary pickling waste liquid Sewage and cleaning waste liquid are very harmful to the environment and have complex components. [0003] There are also serious dangers in the transportation, storage and transportation of untreated wast...

AI Technical Summary

Problems solved by technology

[0005] 1. General sewage treatment plants can only treat domestic sewage or are not open for business (national units);

[0006] 2. Sewage treatment plants that are qualified to treat hazardous waste are often not accepted due to the fact that the annual indicators cannot be exceeded.

[0007] 3. If the cost of acceptance or treatment is as high as 3,000-10,000 yuan / ton, due to the high cost of treatment, some non-standard cleaning engineering companies risk stealing and dumping to endanger the environment, earn high profits, and seriously endanger the environment. High processing costs, high quotations and no competitiveness

[0008] 4. Since it is hazardous waste, it is necessary to find a qualified dangerous goods vehicle for transportation. There are serious dangers in the process of transportation and storage. It is more difficult to find qualified dangerous goods vehicles in remote areas

[0012] Although the waste liquid treatment devices of the above-mentioned patents have movable transportation capabilities, both of the above-mentioned two are used in the field of oilfield waste liquid treatment, and cannot treat other chemical waste liquids, especially those containing soil, waste residue, etc. Pickling waste liquid treatment; moreover, the above two methods cannot fully automatically recycle the waste liquid that still does not meet the standard after treatment, and cannot achieve the purpose of waste liquid treatment quality inspection
