Upflow Adsorption Bed Reactor for Treating Nitrogen and Phosphorus Deficient Organic Chemical Wastewater

Abstract

The invention discloses an upstream adsorption bed reactor for processing organic chemical wastewater deficient in nitrogen and phosphorus. The reactor consists of elution liquid inlets, an adsorbent inlet, a water outlet, a water penetrating plate, a reactor body, an elution liquid outlet, a water inlet, a multifunctional adsorbent and an adsorbent outlet, wherein the reactor body includes two parts: a rectangle and an inverted pyramid connected below; the elution liquid inlets and the adsorbent inlet are arranged at the top of the reactor body, and the two elution liquid inlets are embedded in the adsorbent inlet; the water penetrating plate and the multifunctional adsorbent are arranged in the reactor body, and the multifunctional adsorbent is filled on the lower part of the water penetrating plate; the adsorbent outlet is arranged at the bottom of the reactor body; the elution liquid outlet and the water inlet are positioned at two ends of a diagonal on the adsorbent outlet; and the water outlet is arranged slightly above the outside the reactor body. The upstream adsorption bed reactor has the beneficial effects of high efficiency, low cost and simplicity in operation when being used for processing organic chemical wastewater which is deficient in nitrogen and phosphorus.

Description

technical field [0001] The invention belongs to the technical field of organic wastewater treatment, and in particular relates to an upflow adsorption bed reactor for treating nitrogen and phosphorus-deficient organic chemical wastewater. Background technique [0002] Organic chemical wastewater involves many industries such as energy, minerals, and chemical industry. At present, the domestic technology for treating high-concentration organic wastewater mainly adopts biochemical methods, and the process route basically follows "physical and chemical pretreatment + A / O biochemical treatment + physical and chemical advanced treatment". As a combined water treatment technology, adsorption-biodegradation plays an important role in the treatment of sewage. At present, the most commonly used adsorption materials for adsorbing organic pollutants can be divided into physical adsorption materials, chemical adsorption materials and biological adsorption materials. Among them, physica...
