The invention provides soil ecological system restoring organic fertilizer which is high in content of nutrients available for crops and reasonable in nutrition collocation, is thoroughly decomposed, has a small number of foreign microbes and is high in organic matter content. The soil ecological system restoring organic fertilizer comprises organic raw materials, microbial agents and NPK, wherein the organic raw materials comprise cake fertilizer, green manure, plant protein and biochemical humic acid; the microbial agents comprise nine microbial bacteria such as nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, potassium-releasing bacteria, actinomycetes, saccharomycetes, lactic acid bacteria, photosynthetic bacteria, paenibacillus polymyxa and bacillus subtilis; the NPK accounts for 5-25% of the total fertilizer; the NPK comprises ammonium sulfate, ammonium chloride, ammonium nitrate phosphate, ammonium phosphate, potassium sulfate, potassium chloride, potassium nitrate, magnesium sulfate, zinc sulfate and borax; the organic raw materials are taken as the balance of the fertilizer.

The invention discloses a method for manufacturing ecological building blocks of a riverway protection slope from sewage plant sludge, belonging to the technical fields of resource utilization and environmental protection. The method comprises the following steps of: uniformly mixing and stirring sludge, cement, gravels, sand and water of a sewage plant; and prepressing and forming under a certain pressure and culturing under the steaming and curing condition to manufacture ecological protection slope building blocks for riverway renovation. The invention can solve the problems of sludge disposal and treatment, solves the problem of secondary pollution of heavy metals and pathogens in sludge and realizes the renewable resource recycling of the sludge. The produced ecological building blocks have the advantages of high strength and blush resistance, and N, P and K in the sludge can be used as nutrition matrixes for ecological growth, thus the ecological system of the riverway protection slope can be improved and a favorable riverway landscape is built.

The invention discloses a sediment improver for black and odorous water, which is composed of the following raw material components in percentages by weight: 20-40% of potassium ferrate, 25-35% of quicklime, 5-10% of polyaluminium chloride, 5-15% of potassium persulfate, and 15-25% of zeolite. Through the sediment improver for the black and odorous water provided by the invention, organic matterscan be completely decomposed, eutrophic substances are adsorbed and fixed, the sediment environment is completely changed, so the reproduction and growth of microorganisms and aquatic animals in waterare promoted, thereby accelerating the restoration of ecosystems.

The invention discloses an ecological system for recycling domestic sewage of an apartment. A purified water collecting device is arranged on a lower layer of the ecological system; a sewage temporary storage device is arranged on an upper layer of the ecological system; an intermediate layer of the ecological system is a purified layer; a water supplying pressure pump is arranged on the ecological system. The ecological system disclosed by the invention has the beneficial effects of simple structure, good stress performance and simplicity and convenience in processing; collection and treatment of the domestic sewage are finished, and the cost of building equipment is reduced; water resources are saved, and are sufficiently utilized; the domestic sewage can achieve the aim of recycling, and is quickly collected in a large amount; the sewage temporary storage device can be used for quickly collecting and storing the domestic sewage by a water delivery pipe; the domestic sewage is subjected to water seepage and water purification for a period of following-up time; meanwhile, a real-time monitoring system provides scientific data information for maintaining an ecological engineering system and detecting the effectiveness; the effects of efficiently utilizing the domestic sewage, reducing the water supplying pressure and saving the water resources are realized.
