Currently, the treatment of industrial wastewater discharged into water bodies is becoming increasingly important. In most cases, water purification is accompanied by the process of its disinfection by mixing with chlorine water, which is fed into the mixing chamber of the treated effluents. A large storage tank for water is used for subsequent post-treatment. The main disadvantages of chlorine are high toxicity, allergic reactions caused by it, it forms various compounds in water, which are organochlorine, with mutagenic and carcinogenic effects. Insufficient efficiency of chlorine disinfection is also associated with causative agents of viral and parasitic diseases.
They are used for the purification of a water treatment plant, which should be determined by the following indicators of effluent pollution: composition, form and concentration, regardless of the water source (surface or underground).
The technological line of water preparation at a water supply enterprise includes such treatment methods as: cleaning on membranes, remineralization or correction of the mineral composition of water, ultraviolet disinfection, ozonation, sorption (on activated charcoal), ion exchange methods, reagent treatment, water clarification, deferrization, chlorination, etc. chlorammonization of water, etc. An alternative to chlorination technology for disinfection of treated wastewater is ultraviolet disinfection, which has a number of advantages.
Industrial wastewater is sent to treatment facilities after being freed from heavy metals at local plant sites and after being processed on filters for mechanical cleaning from various oil products and others, including suspended solids. A by-product of the treated wastewater is biomethane gas, which is formed during the fermentation of sludge and is used for the auxiliary needs of the boiler house of the treatment plant.
At industrial enterprises, a storm sewer with a Veksa treatment plant can be installed, which is equipment used for the treatment of industrial wastewater, as well as stormwater. The material for the manufacture of such equipment is glass composite, which is produced in a single housing or in two blocks, or more for the highest productivity.
