【摘要】：本文对含油污泥制备再生胶工业化生产过程中的产污环节和污染源进行分析,并对生产废气、废水以及噪声进行监测;根据监测结果,分别设计了污泥胶粉活化废气、炼胶和硫化车间废气、生产废水污染物处理系统;进一步监测了污染物处理之后,生产废气、废水以及噪音排放情况。油泥制备再生胶工业化生产过程中,废气污染主要来自污泥胶粉活化罐废气、导热油炉烟气、炼胶车间和硫化车间废气;废水污染主要来自污泥胶粉活化高温废气冷凝产生的含油废水;噪声主要来自炼胶机、硫化机等机器工作噪音。对生产废气、废水和噪音进行监测,结果表明:污泥胶粉活化废气、无组织排放废气、生产废水各类污染物均高于国家标准排放限值。针对污泥胶粉活化废气,设计其处理工艺为两级除尘、余热回收、氧化分解除臭、吸附;针对炼胶车间和硫化车间废气,设计其处理工艺为集气罩收集、除尘、吸附并通过15 m排气筒以有组织排放的形式排放;针对生产废水,设计其处理工艺为初步隔油、两级气浮、浮动床过滤。监测结果表明,设计的污泥胶粉活化废气处理系统对颗粒物、非甲烷总烃、臭气浓度的去除率分别为92.8%、91.4%、98.1%;炼胶车间废气处理系统对非甲烷总烃、臭气浓度的去除率分别为84.0%、94.8%;硫化车间废气处理系统对非甲烷总烃、臭气浓度的去除率分别为84.4%、95.2%;生产废水处理系统对污水悬浮物、化学需氧量、生化需氧量、氨氮、总氮、石油类的去除率分别为99.1%、99.2%、99.2%、98.8%、97.1%、99.7%。设计的污泥胶粉活化废气处理系统、炼胶车间和硫化车间废气处理系统以及废水处理系统对污染物的处理效果显著。经污染物处理系统处理后,污泥胶粉活化废气排气筒、炼胶车间废气排气筒、硫化车间废气排气筒、无组织排放废气、生产废水、厂界噪声各类污染物排放均符合相关标准,可以直接外排。
[Abstract]:In this paper, the pollution production and pollution sources in the industrial production of reclaimed rubber from oily sludge are analyzed, and the waste gas, waste water and noise are monitored, according to the monitoring results, the activated waste gas of sludge rubber powder is designed respectively. Rubber and vulcanization workshop exhaust gas, production wastewater pollutant treatment system; further monitoring of waste gas, waste water and noise emissions after pollutant treatment. Waste gas pollution mainly comes from sludge powder activated tank exhaust gas, heat conduction oil furnace flue gas, rubber refining workshop and vulcanization workshop waste gas; waste water pollution mainly comes from oily waste water produced by sludge rubber powder activation and high temperature waste gas condensation; noise mainly comes from rubber refining machine. Working noise of machines such as vulcanization machines. The results of monitoring the production exhaust gas, wastewater and noise show that the sludge rubber powder activates the waste gas and disorganizes the exhaust gas. All kinds of pollutants in production wastewater are higher than the national standard emission limit. For activated waste gas of sludge rubber powder, the treatment process is designed as two-stage dust removal, waste heat recovery, oxidation decomposition and deodorization, adsorption, waste gas from rubber refining workshop and vulcanization workshop, The treatment process is designed as collecting gas hood, collecting dust, adsorbing and discharging through 15m exhaust tube in the form of organized discharge. For the production wastewater, the treatment process is designed as preliminary oil separation, two-stage air floatation and floating bed filtration. The monitoring results show that, The removal rate of particulate matter, non-methane total hydrocarbon and odor concentration by the activated waste gas treatment system of sludge rubber powder is 92.881 / 91.4 and 98.1 respectively. The removal rates of odor concentration are 84.0% and 94.8% respectively; the removal rate of non-methane total hydrocarbon and odor concentration in waste gas treatment system of vulcanization workshop are 84.4% and 95.2%, respectively; the effluent suspended matter, chemical oxygen demand, biochemical oxygen demand, ammonia nitrogen, total nitrogen in the wastewater treatment system, The removal rates of petroleum are 99.1 and 99.2 respectively. The activated waste gas treatment system for sludge rubber powder, the waste gas treatment system for rubber mill and vulcanization workshop and the waste water treatment system designed for sludge rubber powder activation have remarkable effect on the treatment of pollutants. The activated exhaust tube of sludge rubber powder, the exhaust pipe of rubber refining workshop, the exhaust pipe of vulcanization workshop, the unorganized exhaust gas, the production wastewater and the noise of the factory all meet the relevant standards and can be discharged directly.
