Resource-Saving Technology Based on Sewage Sludge

The issues of waste disposal are currently having a global technological and economic complexity. severity the environmental problem is specified by accumulation large volumes various wastes, including sewage sludge (SS). Modern technologies can provide its with benefits. SS rich source nutrients high fertilization potential. This work aims to study utilization wastewater in recycling technology for agriculture. composition urban impact on properties gray forest soil were studied. It was shown that application dose 40-60 t/ha promoted an increase content humus, mobile phosphorus exchangeable potassium decrease acidity. noted studied heavy metals upon introduction doses did not exceed approximate permissible concentration (APC) soil. results showed use as fertilizer restores balance organic matter soils improves their agroecological properties. technology, safe way into valuable complex fertilizer, contributes resource conservation.
