Description

Intelligent modularized pilot test experimental device for industrial wastewater pretreatment

Technical Field

The utility model relates to an industrial wastewater treatment field particularly, relates to an intelligent module ization industrial wastewater preliminary treatment pilot scale experimental apparatus.

Background

With the rapid development of industry, the amount of industrial wastewater and the water quality pollution are large, which is the most important pollution source and has the following characteristics: the method has the advantages of large discharge amount, wide pollution range, complex discharge mode and large water consumption in industrial production, and a part of production water carries raw materials, intermediate products, byproducts, final products and the like. The discharge mode of industrial wastewater is complex, intermittent discharge, continuous discharge, regular discharge, irregular discharge and the like exist, and great difficulty is caused to the prevention and treatment of pollution. The pollutants are various in types and have large concentration fluctuation range. The pollutants have strong toxicity and great harm. The waste water polluted by acid and alkali has irritation and corrosiveness, while the organic oxygen-containing compounds such as aldehyde, ketone, ether and the like have reducibility, can consume dissolved oxygen in water, and leads the water to lack of oxygen to cause death of aquatic organisms. The industrial wastewater contains a large amount of nutrients such as nitrogen, phosphorus, potassium and the like, and can promote the algae to grow in a large amount to consume dissolved oxygen in water, thereby causing eutrophication pollution of the water body. The content of suspended substances in the industrial wastewater is very high, and can reach 3000mg/L, which is 10 times of that of the domestic wastewater. The migration change rules of the discharged pollutants are greatly different, the properties of various pollutants contained in the industrial wastewater are greatly different, and some of the pollutants also have stronger toxicity, larger accumulation and higher stability.

Based on the characteristics of industrial wastewater, aiming at wastewater without treatment experience and complex components, especially toxic and harmful wastewater, a process route, a dosage and operation parameters are determined through a small test and a pilot test.

The industrial wastewater has high concentration and various types of organic pollutants, is difficult to biodegrade and has toxic action on biochemical reaction, and the industrial wastewater is pretreated according to needs in order to improve the biochemical performance of the industrial wastewater and reduce the biological toxicity.

The pH adjusting tank adjusts the pH value of the wastewater by adding acid and alkali into the wastewater, and adjusts the pH value of the wastewater for the treatment requirement of the subsequent process.

The iron-carbon micro-electrolysis tower is a good process for treating waste water by using a metal corrosion principle method to form a primary battery, and is also called an internal electrolysis method, an iron scrap filtration method and the like. The micro-electrolysis technology is an ideal process for treating high-concentration organic wastewater at present, and is also called as an internal electrolysis method. Under the condition of no power supply, the micro-electrolysis material filled in the wastewater generates a 1.2V potential difference to carry out electrolysis treatment on the wastewater so as to achieve the purpose of degrading organic pollutants. The iron-carbon micro-electrolysis has the advantages of wide application range, good treatment effect, low cost, convenient operation and maintenance, no need of consuming power resources, high reaction speed, stable treatment effect, no secondary pollution, improvement on the biodegradability of wastewater, capability of achieving chemical precipitation dephosphorization, capability of removing heavy metals by reduction, capability of being used as pretreatment of biological treatment, and contribution to sludge settlement and biofilm formation. The mature industry at present has: chemical industry, pharmacy, dye, pigment, rubber auxiliary agent, phenolic resin, electroplating, circuit board, landfill leachate, printing and dyeing, coal chemical industry and the like.

The Fenton tower utilizes a Fe2+ homogeneous catalytic reaction to enable an oxidant H2O2 to be catalytically decomposed to generate OH free radical to oxidize and degrade organic matters, so that micromolecular organic matters or inorganic matters are obtained. The combination of H2O2 and Fe2+ is the Fenton reagent which has strong oxidizing ability. The method is suitable for pretreatment and advanced treatment of industrial wastewater, and can be combined with other methods to reduce the cost.

The flocculation precipitation process is a separation technique for removing suspended substances and colloids in wastewater, and is commonly used for pretreatment and primary treatment. Coagulant is added into the wastewater to destroy the stability of colloid, so that the colloid and fine suspended matters in the wastewater are gathered into floccules with separability. The precipitation is to carry out liquid-solid separation on the flocculating constituent, so that harmful substances in the wastewater are concentrated into sludge, the water quality is purified, and the sludge can be subjected to harmless treatment. The technology has the advantages of simple operation, low operation cost, high removal rate which can reach more than fifty percent, high cost performance and wide application. An effective solution to the problems in the related art has not been proposed yet.
