Problems solved by technology

The difficulty of the breakpoint chlorination method lies in the mastery of the breakpoint. When the breakpoint is exceeded, there will be Cl in the water. 2 Residue, the treatment cost of the breakpoint chlorine addition method is 37.6 yuan / kg (NH 3- N), the cost is high, the dosage of chemicals is large, and the salinity of wastewater will be increased at the same time, the effluent is difficult to meet the standard, and chloramine compounds are easy to remain in wastewater, which violates the principle of green chemistry

Abstract

The invention provides an electrochemical ammonium micro-nano reactor, a preparation method of an anode material thereof and ammonium removal application, and belongs to the technical field of sewageammonium removal. The electrochemical ammonium micro-nano reactor comprises an anode material and a cathode material, wherein the anode material and the cathode material are respectively connected with an anode and a cathode of a direct current power supply; a first support plate is provided with a first groove, and the anode material is arranged in the first groove; a second support plate is provided with a second groove, and the cathode material is arranged in the second groove. The anode material comprises an ammonium ion sieve material which exchanges ammonium ions from a water body to enrich the ammonium ions in the water body to an electrochemical anode; and a chloride ion adsorbent absorbing chloride ions in water. After being electrified, the chloride ions are oxidized into chlorine, the chlorine meets water to form active hypochlorite, and the chlorate oxidizes the ammonium ions adsorbed by the ammonium ion sieve into nitrogen. According to the invention, the ammonium ions insewage are adsorbed in large quantities, the chloride ions in water bodies are adsorbed, electrochemical chlorine production efficiency is increased, and cost is saved; the product is clean, the reaction is efficient, reusing can be realized, and the reaction process can be continuously carried out.

Description

technical field [0001] The invention relates to the technical field of ammonium removal from sewage, in particular to an electrochemical ammonium micro-nano reactor and its anode material preparation method and application of ammonium removal. Background technique [0002] For the ammonia nitrogen treatment of the actual municipal water polluted by low concentration ammonia nitrogen, the methods currently used are the ion exchange method and the breakpoint chlorination method. [0003] Ammonia nitrogen in municipal water is mainly in the form of positively charged NH 4 + The basic principle of the ion exchange method to remove ammonia nitrogen is through the exchangeable ions on the ion exchanger and the NH in the wastewater 4 + An exchange reaction occurs to achieve the purpose of removing ammonia nitrogen. The ion exchange method has a good and stable treatment effect on low-concentration ammonia nitrogen wastewater. However, once the saturated adsorption capacity of t...
