Problems solved by technology

[0041] The present invention discovers and proposes for the first time the impact of endocrine disruptors used in marine engineering construction (drilling, oil production, subsea pipeline anticorrosion pretreatment, crude oil demulsifier, drilling equipment cleaning, oil production additives, etc.) on ecology. For the impact on ecology, on the basis of studying the monitoring of the Internet of Things, an efficient and economical solution process is proposed, and efforts are made to overcome the shortcomings of traditional treatment processes such as difficult biodegradation, high treatment costs, difficulty, and low efficiency, and to achieve the removal of endocrine disrupting substances Enrichment, recycling and reuse, reducing emissions, has a unique advantage of circular economy

Abstract

The invention provides an endocrine disruptor-containing pickling wastewater treatment apparatus and a method thereof. Pickling wastewater from China National Offshore Oil Corporation mainly comprises acids, metal ions and organic matters, and the endocrine disruptor is nonylphenol polyoxyethylene ether and is a surface active substance, is a common organic matter used in the coating process of offshore oilfields, and is harmful to the ecology. The wastewater undergoes foam separation, a Fenton oxidation reaction, flocculating precipitation, A2 / O biochemical treatment, a CMF reaction and active carbon filtration to remove harmful substances in the wastewater, and the treated outlet water reaches first stage B standards of Chinese Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant, and can be used in pipeline spray cooling. The apparatus has the advantages of high automation degree, flexible adjustment of the reaction flow, and adaption to different inlet and outlet water quality requirements, and the method has the advantages of COD standard reaching discharge, wastewater treatment cost reduction, and realization of the high effectiveness and the economy of wastewater treatment.

Description

technical field [0001] The invention belongs to the technical field of environmental protection of acid treatment waste liquid, more specifically, for marine engineering associated pickling liquid, the endocrine disruptor contained in it is used as a treatment device and process method of persistent organic matter. Background technique [0002] The main methods currently available for pickling wastewater treatment are classified as follows: [0003] Sulfuric acid pickling wastewater treatment processes mainly include neutralization method, ferric sulfate method, organic solution extraction method, dialysis method, ion exchange method and other methods. The latter three methods are still in the stage of experimental research. In addition, there are iron oxide red sulfur ammonium method, wetland method and biological method. In recent years, "zero discharge" of wastewater has been mentioned more and more frequently in the industrial field, and it has also become an important...
