Sewage purifying and treating device

Abstract

The present invention discloses a sewage purification treatment device, comprising a gas pump. The gas pump is connected with a gas storage tank; the gas storage tank is connected with a gas dissolving tank; the gas dissolving tank is connected with a purification tower through pipelines; a sewage pipe is connected with a gas pipe; a first heat pipe and a second heat pipe are arranged in the purification tower; the first heat pipe and the second heat pipe are respectively connected with a header heat pipe which is connected with a thermodynamic device; a hydraulic distributor is arranged between two mesh-like partition boards; a plurality of through holes are arranged on the pipe wall of the first heat pipe as well as of the second heat pipe. The invention ahs the advantages that the device has an extremely significant effect proved in the trials of several refinery and fertilizer enterprises, and the NH3-N, COD removal rate reaches 94 percent. Upon test, the ammonia and the nitrogen content of the treated water is respectively lower than 0.50 mg / L and COD7000mg / L, and the removal rate reaches 95.6 percent; moreover, a suction ventilator can be easily arranged on the gas exhaust position to collect NH3-N in order to make the NH3-N enter a reaction chamber to react with sulfuric acid to produce ammonium sulfate fertilizer.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a sewage purification treatment device for industrial sewage treatment. Background technique [0002] Industrial sewage pollutes the environment seriously, and causes great harm to human survival and human health. Therefore, in recent years, the state has strictly required all industries to treat sewage before discharging it. In order to solve the problem of sewage discharge reaching the standard, those skilled in the art have provided many sewage treatment methods. It can be seen from the published content that it can be roughly divided into two categories: one is relatively simple in structure, and mainly uses biochemical and chemical methods to treat sewage. Although this method reduces the discharge of harmful substances in the industry, new pollution occurs and cannot To achieve environmental protection of wastewater; the other is equipment with complex structure, which require...

It can be seen from the published content that it can be roughly divided into two categories: one is relatively simple in structure, and mainly uses biochemical and chemical methods to treat sewage. Although this method reduces the discharge of harmful substances in the industry, new pollution occurs and cannot To achieve environmental protection of wastewater; the other type is equipment with complex structure, which requires a large investment, the sewage treatment process is complicated, and the cost of sewage treatment is high, which will greatly reduce the profit of the enterprise, so it cannot be popularized and applied
